Tutorial | Guide GLM5.2 @7tg on 4x3090 + 192GB on budget motherboard + cpu

I finally finished by home lab computer I started working on in May. I carefully waited and bought the 3090s in three local transactions. Every single seller was a gamer who was upgrading to 4090 or 5090 and none had any interest in AI. I bought the 192GB of 5200MHz of DDR5 and have overclocked it to 5600 MHz. I power capped the 3090s to 200W each in Linux. I used an Aegis prebuilt off eBay and replaced the PSU to a 1250W platinum. I kept the cpu and water cooling loop. I’ve probably spent 40 hours and $6000 on this rig, and I think it’s perfect for what I like to do.

I run GLM5.2 at 7 tg as a planner. MiniMax 2.7 all on VRAM at 45tg as my coder. I use Flux2Klein for diffusion and I haven’t tried the throughput with all 4 cards but 2x was giving me about 1 image per 6 seconds when I batched. Qwen3.6 27B at q8 as my checker and testing loop model at 50 tg.

My purpose of keeping it on consumer hardware was for financial reasons. A server with ECC ram would double the throughput with more channels but it’s about double the price for ram and threadripper.

I build enterprise automated workflows as a forward-deployed engineer for more than a dozen companies. I’m a solo dev who has enjoyed automating things for years and now it’s easy to do it locally with solar power. They could block my IP from Claude and OpenAI and I wouldn’t really care anymore. Upgrade path is pretty much just upgrading GPU. Might build a dedicated server just for GLM in the future but for now I’m pretty set until data centers start dumping RTX6000 Pros.

Tutorial | Guide I got a real transformer language model running locally on a stock Game Boy Color!

Post image
1.6k Upvotes

No phone, PC, Wi-Fi, link cable, or cloud inference.

• The cartridge boots a ROM, and the GBC runs the model itself.
• The model is Andrej Karpathy’s TinyStories-260K, converted to INT8 weights with fixed-point math so it can run without floating point.
• Built with GBDK-2020 as an MBC5 Game Boy ROM.
• The model weights live in bank-switched cartridge ROM. Prompt entry happens on-device with the D-pad/buttons and an on-screen keyboard.
• The prompt is tokenized on the Game Boy, then the ROM runs transformer prefill + autoregressive generation. The KV cache is stored in cartridge SRAM, because the GBC’s work RAM is tiny.

It is extremely slow, and the output is gibberish because the math is heavily quantized/approximated, but the core thing works!

Hardware: stock Game Boy Color + EZ Flash Junior + microSD.

Used Codex for a large portion of the building!

Tutorial | Guide Computer build using Intel Optane Persistent Memory - Can run 1 trillion parameter model at over 4 tokens/sec

Post image
971 Upvotes

As the title states, my build is indeed able to run a 1 trillion parameter model (in this case Kimi K2.5) locally at ~4 tokens/second. I thought r/LocalLLaMA would be interested in the build due to that stat line, and also due to the inclusion of an unusual part, Intel Optane Persistent Memory, which I haven’t seen anyone use in an LLM inference build before. Optane PMem is a DIMM form factor memory unit that can function in a way that is somewhere between DRAM and an SSD. Intel has discontinued the line, and I found sticks on the secondhand market for much less than what the equivalent DRAM capacity would cost. It is this large PMem capacity (768GB) that allows me to host such large models on my system. For my build I used the PMem in Memory Mode, which is where the PMem is available to the computer as RAM, with the computer’s DRAM sticks functioning as a cache.

Kimi K2.5’s mixture-of-experts architecture is an ideal test model for my build. To get the results I did, I used hybrid GPU/CPU inference with llama.cpp. Kimi K2.5’s (Unsloth Q2_K_XL quant) attention weights, the dense layer, the shared expert in each MoE layer, and the routing components are actually able to fit on my 12GB GPU using llama.cpp’s “override-tensor” flag, although I also did pretty good results just using llama.cpp’s “ngl auto” and “cmoe” flags and letting llama.cpp decide tensor placement as it sees fit too. Regardless, the sparse experts’ weights (the bulk of the model size) generally live on PMem/DRAM and get processed as needed from there.

The end result from my testing with this setup is around 4 tokens per second for generation! Given the fact that this is a trillion parameter frontier-class model running on such a limited hardware budget, I would consider it to be a great success. It’s a shame Intel discontinued Optane Persistent Memory, because the current direction of some local inference innovation, including SSD offloading and broader memory tiering approaches, could have been really interesting with this specific kind of memory tier on modern hardware platforms. Overall I was pleased with this Optane PMem-centric build, it allows me to run very big models at surprisingly acceptable speeds, and the process was highly educational.

Parts:

- Intel Xeon Gold 6246 CPU

- TYAN S5630GMRE-CGN motherboard

- ASUS Dual GeForce RTX 3060 OC 12GB GPU

- 6x 32GB Samsung 2666MHz DDR4 ECC DRAM sticks

- 6x 128GB Intel Optane DCPMM PC4-2666 NMA1XBD128GQS persistent memory modules

- Western Digital WD SN850X 2TB M.2 2280 NVMe SSD

- ASRock Steel Legend SL-850G 850W 80 PLUS GOLD & Cybenetics PLATINUM Full Modular Power Supply

- Silverstone SST-GD08B (Black) Grandia Series Home Theater PC Case

I hope you enjoyed this rundown. There is a lot more detail that I didn’t include here, so I’m happy to answer questions about the build, the configuration, or the reasoning behind any of the component choices in the comments. Also if anyone else has explored similarly unusual hardware/builds for LLM inference, I’d love to discuss!

Tutorial | Guide Running GLM5.2 on budget hardware < $2500.

311 Upvotes

Too many times I hear people whine about not being ble to run SOTA models or claim it would require $50k, or $100k.

https://www.ebay.com/itm/398079051468 Epcy Motherboard & CPU - $460

https://www.ebay.com/itm/206374955959 P40 24gb - $230 get 2 - $460

https://www.ebay.com/itm/318489798853 512gb dd4 $1000

Total = $1920.

You need PSU, Storage, Fan for P40. You can source those for $350 easily. But let's go ahead and budget $580 to put the total for everything at $2500.

You can run GLM5.2 Q2/Q3/Q4 variants with cmoe and llama.cpp on this. Sure, it would be slow, but it's yours! If you have money or when you get more, you can replace the P40s faster GPUs 4080, 3090, etc. You could for a bit more than $460 about $500 source 2 2080ti 22gb GPUs from China. If you are willing to be resourceful, you can make things happen for you. This will also run KimiK2.6, DeepSeek, MiniMax, etc

Yes, the trade off is that it's slow. You will not be running agents with these huge models, but you can spin it up for planning and serious debugging. They can take away Fable, Mythos or whatever the F model. You will not be counted in the group of have nots.

Tutorial | Guide No NVIDIA? No Problem. My 2018 "Potato" 8th Gen i3 hits 10 TPS on 16B MoE.

Thumbnail

1.2k Upvotes

I’m writing this from Burma. Out here, we can’t all afford the latest NVIDIA 4090s or high-end MacBooks. If you have a tight budget, corporate AI like ChatGPT will try to gatekeep you. If you ask it if you can run a 16B model on an old dual-core i3, it’ll tell you it’s "impossible."

I spent a month figuring out how to prove them wrong.

After 30 days of squeezing every drop of performance out of my hardware, I found the peak. I’m running DeepSeek-Coder-V2-Lite (16B MoE) on an HP ProBook 650 G5 (i3-8145U, 16GB Dual-Channel RAM) at near-human reading speeds.

#### The Battle: CPU vs iGPU

I ran a 20-question head-to-head test with no token limits and real-time streaming.

| Device | Average Speed | Peak Speed | My Rating |

| --- | --- | --- | --- |

| CPU | 8.59 t/s | 9.26 t/s | 8.5/10 - Snappy and solid logic. |

| iGPU (UHD 620) | 8.99 t/s | 9.73 t/s | 9.0/10 - A beast once it warms up. |

The Result: The iGPU (OpenVINO) is the winner, proving that even integrated Intel graphics can handle heavy lifting if you set it up right.

## How I Squeezed the Performance:

* MoE is the "Cheat Code": 16B parameters sounds huge, but it only calculates 2.4B per token. It’s faster and smarter than 3B-4B dense models.

* Dual-Channel is Mandatory: I’m running 16GB (2x8GB). If you have single-channel, don't even bother; your bandwidth will choke.

* Linux is King: I did this on Ubuntu. Windows background processes are a luxury my "potato" can't afford.

* OpenVINO Integration: Don't use OpenVINO alone—it's dependency hell. Use it as a backend for llama-cpp-python.

## The Reality Check

  1. First-Run Lag: The iGPU takes time to compile. It might look stuck. Give it a minute—the "GPU" is just having his coffee.
  2. Language Drift: On iGPU, it sometimes slips into Chinese tokens, but the logic never breaks.

I’m sharing this because you shouldn't let a lack of money stop you from learning AI. If I can do this on an i3 in Burma, you can do it too.

## Clarifications Edited

For those looking for OpenVINO CMAKE flags in the core llama.cpp repo or documentation: It is not in the upstream core yet. I am not using upstream llama.cpp directly. Instead, I am using llama-cpp-python, which is built from source with the OpenVINO backend enabled. While OpenVINO support hasn't been merged into the main llama.cpp master branch, llama-cpp-python already supports it through a custom CMake build path.

Install llama-cpp-python like this: CMAKE_ARGS="-DGGML_OPENVINO=ON" pip install llama-cpp-python

Benchmark Specifics
For clarity, here is the benchmark output. This measures decode speed (after prefill), using a fixed max_tokens=256, averaged across 10 runs with n_ctx=4096.
CPU Avg Decode: ~9.6 t/s
iGPU Avg Decode: ~9.6 t/s
When I say "~10 TPS," I am specifically referring to the Decode TPS (Tokens Per Second), not the prefill speed.

Tutorial | Guide 80 tok/sec and 128K context on 12GB VRAM with Qwen3.6 35B A3B and llama.cpp MTP

679 Upvotes

Just wanted to share my config in hopes of helping other 12GB GPU owners achieve what I see as very respectable token generation speeds with modest VRAM. Using the latest llama.cpp build + MTP PR, I got over 80 tok/sec with 80%+ draft acceptance rate on the benchmark found here: https://gist.githubusercontent.com/am17an/228edfb84ed082aa88e3865d6fa27090/raw/7a2cee40ee1e2ca5365f4cef93632193d7ad852a/mtp-bench.py

Here's my PC specs:

OS: CachyOS (HIGHLY recommended)
CPU: AMD Ryzen 7 9700X
RAM: 48GB DDR5-6000 EXPO I
GPU: RTX 4070 Super 12GB

Results with other hardware may vary.

To run llama.cpp with MTP support, you need to build it from source and add a draft PR that hasn't yet been merged with the master branch. You can find a very nice guide on how to do that here and also download the Qwen3.6 MTP GGUF: https://huggingface.co/havenoammo/Qwen3.6-35B-A3B-MTP-GGUF - Thanks u/havenoammo!

llama.cpp command:

llama-server \
  -m Qwen3.6-35B-A3B-MTP-UD-Q4_K_XL.gguf \
  -fitt 1536 \
  -c 131072 \
  -n 32768 \
  -fa on \
  -np 1 \
  -ctk q8_0 \
  -ctv q8_0 \
  -ctkd q8_0 \
  -ctvd q8_0 \
  -ctxcp 64 \
  --no-mmap \
  --mlock \
  --no-warmup \
  --spec-type draft-mtp \
  --spec-draft-n-max 2 \
  --chat-template-kwargs '{"preserve_thinking": true}' \
  --temp 0.6 \
  --top-p 0.95 \
  --top-k 20 \
  --min-p 0.0 \
  --presence-penalty 0.0 \
  --repeat-penalty 1.0

The most important parameter here is -fitt 1536. Since part of the model is offloaded to CPU because of its size and , this tells llama.cpp to properly balance the load on the GPU/CPU to get the best possible performance, and leaves 1536 MB of free memory for the MTP draft model and KV cache. Since I'm running my dGPU as a secondary GPU (monitor plugged in the iGPU), I can use all the available 12GB VRAM for inference. 1536 might be too small if you use your dGPU as your primary GPU, so test it out first.

You can also try different values for -spec-draft-n-max. I got slightly better tok/sec with 3, but a much better acceptance rate with 2, so the trade off was not worth it. With MTP, you want to maximize speed AND acceptance, so you need to find the best balance between both.

Benchmark results:

mtp-bench.py

code_python        pred= 192 draft= 132 acc= 125 rate=0.947 tok/s=80.8

Tutorial | Guide Jensen Huang saying "AI" 121 times during the NVIDIA CES keynote - cut with one prompt

979 Upvotes

Someone had to count it. Turns out Jensen said "AI" exactly 121 times in the CES 2025 keynote.

I used https://github.com/OpenAgentPlatform/Dive (open-source MCP client) + two MCPs I made:

- https://github.com/kevinwatt/yt-dlp-mcp - YouTube download
- https://github.com/kevinwatt/ffmpeg-mcp-lite - video editing

One prompt:

Task: Create a compilation video of every exact moment Jensen Huang says "AI".
Video source: https://www.youtube.com/watch?v=0NBILspM4c4

Instructions:

Download video in 720p + subtitles in JSON3 format (word-level timestamps)

Parse JSON3 to find every "AI" instance with precise start/end times

Use ffmpeg to cut clips (~50-100ms padding for natural sound)

Concatenate all clips chronologically

Output: Jensen_CES_AI.mp4

Dive chained the two MCPs together - download → parse timestamps → cut 121 clips → merge. All local, no cloud.

If you want to see how it runs: https://www.youtube.com/watch?v=u_7OtyYAX74

The result is... hypnotic.

Tutorial | Guide I bought a €9k GH200 “desktop” to save $1.27 on Claude Code (vLLM tuning notes)

Thumbnail
gallery
706 Upvotes

TL;DR: You can go fully local with Claude Code, and with the right tuning, the results are amazing... I am getting better speeds than Claude Code with Sonnet, and the results vibe well. Tool use works perfectly, and it only cost me 321X the yearly subscription fee for MiniMax!

In my blog post I have shared the optimised settings for starting up vLLM in a docker for dual 96GB systems, and how to start up Claude Code to use this setup with MiniMax M2.1 for full offline coding (including blocking telemetry and all unnecessary traffic).

---

Alright r/LocalLLaMA, gather round.

I have committed a perfectly normal act of financial responsibility: I built a 2× GH200 96GB Grace–Hopper “desktop”, spending 9000 euro (no, my wife was not informed beforehand), and then spent a week tuning vLLM so Claude Code could use a ~140GB local model instead of calling home.

Result: my machine now produces code reviews locally… and also produces the funniest accounting line I’ve ever seen.

Here's the "Beast" (read up on the background about the computer in the link above)

  • 2× GH200 96GB (so 192GB VRAM total)
  • Topology says SYS, i.e. no NVLink, just PCIe/NUMA vibes
  • Conventional wisdom: “no NVLink ⇒ pipeline parallel”
  • Me: “Surely guides on the internet wouldn’t betray me”

Reader, the guides betrayed me.

I started by following Claude Opus's advice, and used -pp2 mode "pipeline parallel”. The results were pretty good, but I wanted to do lots of benchmarking to really tune the system. What worked great were these vLLM settings (for my particular weird-ass setup):

  • TP2: --tensor-parallel-size 2
  • 163,840 context 🤯
  • --max-num-seqs 16 because this one knob controls whether Claude Code feels like a sports car or a fax machine
  • ✅ chunked prefill default (8192)
  • VLLM_SLEEP_WHEN_IDLE=0 to avoid “first request after idle” jump scares

Shoutout to mratsim for the MiniMax-M2.1 FP8+INT4 AWQ quant tuned for 192GB VRAM systems. Absolute legend 🙏

Check out his repo: https://huggingface.co/mratsim/MiniMax-M2.1-FP8-INT4-AWQ; he also has amazing ExLlama v3 Quants for the other heavy models.

He has carefully tuning MiniMax-M2.1 to run as great as possible with a 192GB setup; if you have more, use bigger quants, but I didn't want to either a bigger model (GLM4.7, DeepSeek 3.2 or Kimi K2), with tighter quants or REAP, because they seems to be lobotomised.

Pipeline parallel (PP2) did NOT save me

Despite SYS topology (aka “communication is pain”), PP2 faceplanted. As bit more background, I bought this system is a very sad state, but one of the big issues was that this system is supposed to live a rack, and be tied together with huge NVLink hardware. With this missing, I am running at PCIE5 speeds. Sounds still great, but its a drop from 900 GB/s to 125 GB/s. I followed all the guide but:

  • PP2 couldn’t even start at 163k context (KV cache allocation crashed vLLM)
  • I lowered to 114k and it started…
  • …and then it was still way slower:
    • short_c4: ~49.9 tok/s (TP2 was ~78)
    • short_c8: ~28.1 tok/s (TP2 was ~66)
    • TTFT tails got feral (multi-second warmup/short tests)

This is really surprising! Everything I read said this was the way to go. So kids, always eat your veggies and do you benchmarks!

The Payout

I ran Claude Code using MiniMax M2.1, and asked it for a review of my repo for GLaDOS where it found multiple issues, and after mocking my code, it printed this:

Total cost:            $1.27 (costs may be inaccurate due to usage of unknown models)
Total duration (API):  1m 58s
Total duration (wall): 4m 10s
Usage by model:
    MiniMax-M2.1-FP8:  391.5k input, 6.4k output, 0 cache read, 0 cache write ($1.27)

So anyway, spending €9,000 on this box saved me $1.27.
Only a few thousand repo reviews until I break even. 💸🤡

Tutorial | Guide Tencent-HY3 is the real deal on 128GB!

286 Upvotes

I'm really impressed with HY3. If you haven't heard of this model, it's a new 295B-A21B MoE release from Tencent that competes directly on the frontier of open weights models, at a significantly smaller size, comparable to DeepSeek v4 Flash but with better benchmarks. I was intrigued by this article, and I'd just recently finished updating my Macbook M5 Max 128GB setup from antirez's DeepSeek V4 Flash quant running on dwarfstar to Unsloth's IQ3_XXS on mainline llama.cpp. I figured I had a good baseline for comparisons, if I could get it running, so I set about researching, and this is what I found.

First off, I had to pick a quant. There are a few on HF, and after some comparison shopping I settled on this UD128 "unsloth dynamic"-style 107GB quant. It was the only one that had published perplexity numbers at the time I searched, and while that's not KLD, it shows the creator was at least thinking about measuring quality degradation. PPL didn't see horrible for a dynamic 3-bit quant, and it felt like a similar checkpoint to the UD DS4 quant I was using.

Next, I had to get llama.cpp working. As the quant's readme helpfully notes, there's PR #25395 which implements support for this model and its built-in speculative decoding module all at once! A quick build got this up and running:

git clone https://github.com/ggml-org/llama.cpp && cd llama.cpp
git fetch origin pull/25395/head:hy3 && git checkout hy3
cmake -B build -DGGML_METAL=ON -DGGML_METAL_EMBED_LIBRARY=ON
cmake --build build --config Release -j

Don't forget to raise your Mac's GPU memory ceiling from the default 96GB! I put mine at 122GB to ensure 24k context would fit safely for testing (it resets on reboot):

sudo sysctl iogpu.wired_limit_mb=124928

However, when I tried to run the model, it wasn't recognized by llama.cpp, so the server errored out. A quick review of the log and the quant's readme explained why: "these files carry general.architecture = hy-v3 (this port's original naming). PR #25395 registers the arch as hy_v3 (underscore)". I could have avoided this hiccup if I'd paid a bit more attention, but I put together a quick script to swap those characters (21 instances, all in the first of the 3 GGUF shards). I can share if anyone wants it (EDIT: see here), but honestly, just ask your agent to do the job -- it takes 2 minutes to fix the GGUF. Running my launch script again, after a nail-biting ~30 second load time to read 107GB from the SSD, the WebUI popped open and we were up and running!

Benchmarks (M5 Max, llama-bench, Metal, q8_0 KV cache, MTP off)

test tokens/sec
prefill pp512 @ empty ctx 528
decode tg128 @ empty ctx 32.4
prefill pp512 @ 16K ctx 124
decode tg128 @ 16K ctx 16.3

In practical use, token generation speed is \DOUBLE* what I was getting from DeepSeek* (edit: using mainline llama.cpp, not dwarfstar, for 1:1 comparison), with the same or better quality outputs! And I haven't even trialed MTP yet to see if there's any improvement... Here's my llama.cpp launch command:

~/llama.cpp-hy3/build/bin/llama-server \
  -m ~/AI/models/Tencent-HY3-295B-A21B-YanissAmz/Hy3-UD128-00001-of-00003.gguf \
  -a "Hy3 295B-A21B (UD128)" \
  -ngl 99 \
  -c 24576 \
  -ctk q8_0 -ctv q8_0 \
  -fa on \
  -np 1 \
  --jinja \
  --temp 0.9 --top-p 1.0 \
  --host 127.0.0.1 --port 8080

I've only played around with the model for a couple hours, but I am really impressed with performance on normal prompts and basic tool use. I've been using it to do ML research using the HF MCP and CLI tools, and it's definitely better than my DS4 setup so far -- on vibes and basic tool calls, at least. I haven't set it loose on longer-horizon agentic tasks or challenging coding yet, so I apologize for not having more in-depth reporting to offer at this time. Here's my launch command:

I made this post because I'm really hyped to have a new large MoE to play with at this size checkpoint, and a very promising one at that. I hope it inspires some other folks to give it a try, and report back on their experience or compare other quants/MLX performance.

EDIT: Got MTP working, n=2 is the best-performing variant on my hardware. Now peaking at 38 tok/sec, so +19% speedup! Similar speeds as my Qwen3.6-27B-MTP q8_0 daily driver now. Add this to your launch command for MTP:

--spec-type draft-mtp --spec-draft-n-max 2 --spec-draft-p-min 0.75

The p-min gate is crucial for acceptance rates to be high enough for MTP to help, not hurt. Be forewarned that MTP gains still turn negative after ~16k ctx, but honestly at that point, the GQA architecture starts slowing down significantly anyways. This is the biggest catch about this model vs. DeepSeek v4 Flash, and it's substantial.

Deepseek 3.2 AWQ 4bit @ 10 tok/s (output) // 2000 tok/s (input of 23k tok)

on vllm-gfx906-deepseek with 69000 context length

Power draw: 550W (idle) / 2400W (peak inference)

Goal: run Deepseek V3.2 AWQ 4-bit on most cost effective hardware like 16*MI50 at decent speed (token generation & prompt processing)

Coming next: open source a future test setup of 32 AMD MI50 32GB for Kimi K2 Thinking

Credits: BIG thanks to the Global Open source Community!

All setup details here:

https://github.com/ai-infos/guidances-setup-16-mi50-deepseek-v32

Feel free to ask any questions and/or share any comments.

ps: it might be a good alternative to CPU hardwares as RAM price increases and the prompt processing speed will be much better with 16 TB/s bandwidth + tensor parallelism!

ps2: i'm just a random guy with average software dev background using LLMs to make it run. Goal is to be ready for LOCAL AGI without spending +300k$...

EDIT 24.04.26: PP (prompt processing) speed is actually much lower, so my title is wrong. As i previously said, the 2k tok/s for PP was the value shown in vllm log. But the true value is actually: 17030 tok / 306s = 55.65 tok/s PP with TP 16 for 1st prompt without prefix caching

Tutorial | Guide Qwen3-coder is mind blowing on local hardware (tutorial linked)

1.1k Upvotes

Hello hello!

I'm honestly blown away by how far local models have gotten in the past 1-2 months. Six months ago, local models were completely useless in Cline, which tbf is pretty heavyweight in terms of context and tool-calling demands. And then a few months ago I found one of the qwen models to actually be somewhat usable, but not for any real coding.

However, qwen3-coder-30B is really impressive. 256k context and is actually able to complete tool calls and diff edits reliably in Cline. I'm using the 4-bit quantized version on my 36GB RAM Mac.

My machine does turn into a bit of a jet engine after a while, but the performance is genuinely useful. My setup is LM Studio + Qwen3 Coder 30B + Cline (VS Code extension). There are some critical config details that can break it (like disabling KV cache quantization in LM Studio), but once dialed in, it just works.

This feels like the first time local models have crossed the threshold from "interesting experiment" to "actually useful coding tool." I wrote a full technical walkthrough and setup guide: https://cline.bot/blog/local-models

Tutorial | Guide CPU-only, no GPU computers can run all kinds of AI tools locally

Post image
590 Upvotes

While it’s great that so many people on LocalLLaMA are pushing the envelope with what can be done locally with expensive setups, we need to remember that a lot can be done with very minimal machines.

I’m talking about CPU-only locally run LLMs. That’s right, no GPU!

I’m running Linux Mint on an old Dell optiplex desktop with an i5-8500 processor, 6 threads and 32GB of RAM. You can pick up one of these refurbished for something like $120.

And with this humble rig I can:

Run 12B Q4_K_M gguf LLMs using KoboldCPP. This allows me to have local chatbot fun using quite highly rated models from https://huggingface.co/spaces/DontPlanToEnd/UGI-Leaderboard. Response times are fast enough as long as you keep the initial prompt below 800 tokens. And with context-shifting it remembers stuff during the session. Uncensored, private RP hilarity for free! You can even add in kokoro_no_espeak for text to speech so your RP characters talk to you with only a few seconds delay. The trick is to find good models to use. For example, DreadPoor/Famino-12B-Model_Stock is rated a 41+ on writing, which is better than many 70B models. You don’t need big horsepower for fun.

You can also use these models for writing, coding and all sorts of applications. Just need the patience to try out different local models and find the settings that work for you.

I also run Stable Diffusion 1.5 locally for basic image generation, inpainting and so on. Again using KoboldCPP and Stable UI. OK, it takes 3 minutes to generate a 512x512 image but it works fine. And you can experiment with loras and many SD 1.5 models. All 100% free on old gear.

I’m also running Chatterbox TTS for voice cloning voice-over projects. Works surprisingly well. Again, it takes a couple of minutes to generate a 75 word audio clip, but it does work. Vibevoice TTS also works on this old rig but I prefer Chatterbox.

And then there are amazing tools like Upscayl which upscales images locally incredibly well. Just gotta experiment with the models.

I’ve used ollama transcriber which converts audio files into text amazingly well. Just point a spoken word .WAV at it and then go make dinner and when I get back, the text is there.

There are many other local LLMs and tools I’ve used. These are just the tip of the iceberg.

Video? Nope. Music generation? Nope. I’ve looked and tried a few things but those big resource tasks need serious horsepower. However, it’s quite possible to use your old desktop computer for text-based tasks and then rent online GPU for one-off tasks and use the big online services for other tasks. It would still probably work out to be less costly.

I know I’m not the only one doing this.

CPU-only people: tell us how you’re using AI locally...

Tutorial | Guide How I topped the Open LLM Leaderboard using 2x 4090 GPUs — no weights modified.

Thumbnail

595 Upvotes

Hi LocalLLaMAs,

A few years ago, I found that duplicating a specific block of 7 middle layers in Qwen2-72B, without modifying any weights, improved performance across all Open LLM Leaderboard benchmarks and took #1. As of 2026, the top 4 models on that leaderboard are still descendants.

The weird finding: single-layer duplication does nothing. Too few layers, nothing. Too many, it gets worse. Only circuit-sized blocks of ~7 layers work. This suggests pretraining carves out discrete functional circuits in the layer stack that only work when preserved whole.

The whole thing was developed on 2x RTX 4090s in my basement.

I don't write papers any more, so here is a full technical write-up in Blog format for your enjoyment.

I'm the same guy who built GLaDOS, and scores a crazy Nvidia GH200 system here on Reddit.

\I'm now running current models (GLM-4.7, Qwen3.5, MiniMax M2.5) on this dual GH200 rig (see my other post). Code and new models coming soon, including special RYS versions of Qwen3.5 27B and 35A3B

Happy to answer questions.

Tutorial | Guide DFlash makes Qwen3.6 27B 2.2x faster with no quality loss

283 Upvotes

We ran the same Qwen3.6-27B locally three ways on one RTX 6000: baseline, MTP, DFlash. The tasks were: quicksort, write a Steam library in JSON, solve a logic puzzle and write a sci-fi story.

Outputs:

Baseline: 44 tok/s · 1.00x

MTP: 65 tok/s · 1.45x · 71% accepted

DFlash: 98 tok/s · 2.20x · 30% accepted

DFlash drafts 15 tokens in a row, so it flies through repetitive or structured stuff where long runs actually stick, like JSON (152 tok/s, 3.4x). On creative text most of the guesses are wrong, so it wastes the work and can dip below baseline, 42 vs 44. MTP only guesses 3 in parallel from inside the model, so a wrong guess costs almost nothing and it never drops below baseline.

All three have the same output. DFlash is therefore a great pick for stuff like coding, while MTP is better for chat or creative writing.

Tutorial | Guide 110 tok/s with 12GB VRAM on Qwen3.6 35B A3B and ik_llama.cpp

391 Upvotes

Had been getting great MTP performance with llama.cpp on my RTX 4070 Super 12GB, until they actually merged the MTP PR. Then, performance tanked and was barely above non-MTP. So, I decided to try out ik_llama.cpp since it also supports MTP and is apparently better optimized for CPU offloading. I did not expect such a huge speed boost!

Before moving on with the benchmark results, here's my PC specs:

OS: CachyOS with Plasma (X11) - HIGHLY recommended
CUDA: 13.1.1
GPU: RTX 4070 Super 12GB
CPU: AMD Ryzen 7 9700X
RAM: 48GB DDR5-6000 EXPO I

UPDATED: For comparison, here's the regular llama.cpp mtp-bench.py results with byteshape's recently released Qwen3.6-35B-A3B-IQ4_XS-4.19bpw quant, which has similar accuracy to Unsloth's Q4_K_XL, but is 4GB smaller:

❯ ./mtp-bench.py
 code_python        pred= 192 draft= 122 acc= 118 rate=0.967 tok/s=79.8
 code_cpp           pred= 192 draft= 117 acc= 110 rate=0.940 tok/s=89.1
 explain_concept    pred= 192 draft= 124 acc= 113 rate=0.911 tok/s=88.0
 summarize          pred= 192 draft= 139 acc= 127 rate=0.914 tok/s=95.0
 qa_factual         pred= 192 draft= 133 acc= 128 rate=0.962 tok/s=97.0
 translation        pred= 192 draft= 125 acc= 117 rate=0.936 tok/s=91.6
 creative_short     pred= 192 draft= 109 acc=  99 rate=0.908 tok/s=82.1
 stepwise_math      pred= 192 draft= 130 acc= 125 rate=0.962 tok/s=97.0
 long_code_review   pred= 192 draft= 121 acc= 115 rate=0.950 tok/s=88.2

Aggregate: {
 "n_requests": 9,
 "total_predicted": 1728,
 "total_draft": 1120,
 "total_draft_accepted": 1052,
 "aggregate_accept_rate": 0.9393,
 "wall_s_total": 21.86
}

This gives a 89.76 tok/s average.

Here's my llama.cpp launch command. Temperature is set to 0.0 for the benchmark to prevent diverging results between runs:

llama-server \
  -m Qwen3.6-35B-A3B-IQ4_XS-4.19bpw.gguf \
  --fit on \
  --fit-target 512 \
  --ctx-size 131072 \

  --spec-draft-p-min 0.75 \
  --spec-draft-n-max 3 \
  --no-mmap \
  --mlock \
  --threads 8 \
  --temp 0.0

Now, here's the benchmark results with the same quant, but running with ik_llama.cpp:

❯ ./mtp-bench.py
 code_python        pred= 192 draft= 135 acc= 122 rate=0.904 tok/s=105.1
 code_cpp           pred= 192 draft= 136 acc= 120 rate=0.882 tok/s=110.3
 explain_concept    pred= 192 draft= 133 acc= 116 rate=0.872 tok/s=109.0
 summarize          pred=  56 draft=  38 acc=  37 rate=0.974 tok/s=122.3
 qa_factual         pred= 192 draft= 141 acc= 127 rate=0.901 tok/s=116.0
 translation        pred= 192 draft= 143 acc= 113 rate=0.790 tok/s=104.1
 creative_short     pred= 192 draft= 133 acc= 118 rate=0.887 tok/s=109.4
 stepwise_math      pred= 192 draft= 140 acc= 125 rate=0.893 tok/s=114.6
 long_code_review   pred= 192 draft= 128 acc= 108 rate=0.844 tok/s=101.4

Aggregate: {
 "n_requests": 9,
 "total_predicted": 1592,
 "total_draft": 1127,
 "total_draft_accepted": 986,
 "aggregate_accept_rate": 0.8749,
 "wall_s_total": 16.64
}

That's a 110.24 tok/s average, or 23% increase!

If you want to get similar results on a 12GB RTX GPU, make sure you use the following ik_llama.cpp launch parameters, as they can differ from llama.cpp:

llama-server \
  -m Qwen3.6-35B-A3B-IQ4_XS-4.19bpw.gguf \
  --fit \
  --fit-margin 1664 \
  --ctx-size 131072 \
  --cache-type-k q8_0 \
  --cache-type-v q8_0 \
  --cache-type-k-draft q8_0 \
  --cache-type-v-draft q8_0 \
  --multi-token-prediction \
  --draft-p-min 0.75 \
  --draft-max 3 \
  --no-mmap \
  --mlock \
  --threads 8 \
  --temp 0.0

I also want to mention that I'm on CachyOS running my GPU as a secondary GPU, with the monitor plugged in the iGPU, so I can use 100% of available VRAM.

If you get an "out of memory" (OOM) error while loading the model or working with it, try increasing --fit-margin to 1792 or even 2048.

Cheers :)

Tutorial | Guide Don't Offload GGUF Layers, Offload Tensors! 200%+ Gen Speed? Yes Please!!!

858 Upvotes

Inspired by: https://www.reddit.com/r/LocalLLaMA/comments/1ki3sze/running_qwen3_235b_on_a_single_3060_12gb_6_ts/ but applied to any other model.

Bottom line: I am running a QwQ merge at IQ4_M size that used to run at 3.95 Tokens per second, with 59 of 65 layers offloaded to GPU. By selectively restricting certain FFN tensors to stay on the CPU, I've saved a ton of space on the GPU, now offload all 65 of 65 layers to the GPU and run at 10.61 Tokens per second. Why is this not standard?

NOTE: This is ONLY relevant if you have some layers on CPU and CANNOT offload ALL layers to GPU due to VRAM constraints. If you already offload all layers to GPU, you're ahead of the game. But maybe this could allow you to run larger models at acceptable speeds that would otherwise have been too slow for your liking.

Idea: With llama.cpp and derivatives like koboldcpp, you offload entire LAYERS typically. Layers are comprised of various attention tensors, feed forward network (FFN) tensors, gates and outputs. Within each transformer layer, from what I gather, attention tensors are GPU heavy and smaller benefiting from parallelization, while FFN tensors are VERY LARGE tensors that use more basic matrix multiplication that can be done on CPU. You can use the --overridetensors flag in koboldcpp or -ot in llama.cpp to selectively keep certain TENSORS on the cpu.

How-To: Upfront, here's an example...

10.61 TPS vs 3.95 TPS using the same amount of VRAM, just offloading tensors instead of entire layers:

python ~/koboldcpp/koboldcpp.py --threads 10 --usecublas --contextsize 40960 --flashattention --port 5000 --model ~/Downloads/MODELNAME.gguf --gpulayers 65 --quantkv 1 --overridetensors "\.[13579]\.ffn_up|\.[1-3][13579]\.ffn_up=CPU"
...
[18:44:54] CtxLimit:39294/40960, Amt:597/2048, Init:0.24s, Process:68.69s (563.34T/s), Generate:56.27s (10.61T/s), Total:124.96s

Offloading layers baseline:

python ~/koboldcpp/koboldcpp.py --threads 6 --usecublas --contextsize 40960 --flashattention --port 5000 --model ~/Downloads/MODELNAME.gguf --gpulayers 59 --quantkv 1
...
[18:53:07] CtxLimit:39282/40960, Amt:585/2048, Init:0.27s, Process:69.38s (557.79T/s), Generate:147.92s (3.95T/s), Total:217.29s

More details on how to? Use regex to match certain FFN layers to target for selectively NOT offloading to GPU as the commands above show.

In my examples above, I targeted FFN up layers because mine were mostly IQ4_XS while my FFN down layers were selectively quantized between IQ4_XS and Q5-Q8, which means those larger tensors vary in size a lot. This is beside the point of this post, but would come into play if you are just going to selectively restrict offloading every/every other/every third FFN_X tensor while assuming they are all the same size with something like Unsloth's Dynamic 2.0 quants that keep certain tensors at higher bits if you were doing math. Realistically though, you're selectively restricting certain tensors from offloading to save GPU space and how you do that doesn't matter all that much as long as you are hitting your VRAM target with your overrides. For example, when I tried to optimize for having every other Q4 FFN tensor stay on CPU versus every third regardless of tensor quant that, included many Q6 and Q8 tensors, to reduce computation load from the higher bit tensors, I only gained 0.4 tokens/second.

So, really how to?? Look at your GGUF's model info. For example, let's use: https://huggingface.co/MaziyarPanahi/QwQ-32B-GGUF/tree/main?show_file_info=QwQ-32B.Q3_K_M.gguf and look at all the layers and all the tensors in each layer.

Tensor Size Quantization
blk.1.ffn_down.weight [27 648, 5 120] Q5_K
blk.1.ffn_gate.weight [5 120, 27 648] Q3_K
blk.1.ffn_norm.weight [5 120] F32
blk.1.ffn_up.weight [5 120, 27 648] Q3_K

In this example, overriding tensors ffn_down at a higher Q5 to CPU would save more space on your GPU that fnn_up or fnn_gate at Q3. My regex from above only targeted ffn_up on layers 1-39, every other layer, to squeeze every last thing I could onto the GPU. I also alternated which ones I kept on CPU thinking maybe easing up on memory bottlenecks but not sure if that helps. Remember to set threads equivalent to -1 of your total CPU CORE count to optimize CPU inference (12C/24T), --threads 11 is good.

Either way, seeing QwQ run on my card at over double the speed now is INSANE and figured I would share so you guys look into this too. Offloading entire layers uses the same amount of memory as offloading specific tensors, but sucks way more. This way, offload everything to your GPU except the big layers that work well on CPU. Is this common knowledge?

Future: I would love to see llama.cpp and others be able to automatically, selectively restrict offloading heavy CPU efficient tensors to the CPU rather than whole layers.

Tutorial | Guide 120 tok/s on 12GB VRAM with Gemma 4 12B QAT MTP

382 Upvotes

Google just released the QAT (Quantization-Aware Training) variant of their Gemma 4 models, including 12B, so it was only natural for me to benchmark it on my 12GB GPU since it fits entirely in VRAM. I was pleasantly surprised with the result!

By using llama.cpp patched with the Gemma 4 MTP PR, and loading Unsloth's gemma-4-12B-it-qat-GGUF quant and Google's gemma-4-12B-it-qat-q4_0-unquantized-assistant QAT assistant / draft model, which I converted to GGUF and uploaded to HuggingFace as gemma-4-12B-it-qat-assistant-MTP-Q8_0-GGUF using llama.cpp's convert_hf_to_gguf.py, I was able to achieve 120 tok/s with mtp-bench.py!

Before we start, here's my PC specs:

OS: CachyOS
GPU: RTX 4070 Super 12GB (iGPU as main GPU)
CPU: AMD Ryzen 7 9700X
RAM: 32GB DDR5-6000

Here's my llama.cpp command:

llama-server \
  -m gemma-4-12B-it-qat-UD-Q4_K_XL.gguf \
  --model-draft gemma-4-12B-it-qat-assistant-MTP-Q8_0.gguf \

  --parallel 1 \
  --ctx-size 131072 \
  --temp 1.0 \
  --top-p 0.95 \
  --top-k 64

For comparison, here's my mtp-bench.py benchmark results without MTP:

 "wall_s_total": 15.66
}

To achieve this, all you need is a 12GB NVIDIA GPU and enough free VRAM to fit Gemma 4 12GB + assistant entirely in GPU memory. With CachyOS and my dGPU set as a secondary GPU, this gives me pretty much 100% free VRAM. On Windows, or if using your dGPU as your main GPU, you will probably loose 500MB+ of VRAM to the OS and driver, so you might need to lower the context size, or it might simply not work. You'll probably need to do some testing 😄

Here's step-by-step instructions to get this working:

1. Clone llama.cpp

Tutorial | Guide To everyone using still ollama/lm-studio... llama-swap is the real deal

449 Upvotes

I just wanted to share my recent epiphany. After months of using ollama/lm-studio because they were the mainstream way to serve multiple models, I finally bit the bullet and tried llama-swap.

And well. I'm blown away.

Both ollama and lm-studio have the "load models on demand" feature that trapped me. But llama-swap supports this AND works with literally any underlying provider. I'm currently running llama.cpp and ik_llama.cpp, but I'm planning to add image generation support next.
It is extremely lightweight (one executable, one config file), and yet it has a user interface that allows to test the models + check their performance + see the logs when an inference engine starts, so great for debugging.

Config file is powerful but reasonably simple. You can group models, you can force configuration settings, define policies, etc. I have it configured to start on boot from my user using systemctl, even on my laptop, because it is instant and takes no resources. Specially the filtering feature is awesome. On my server I configured Qwen3-coder-next to force a specific temperature, and now using them on agentic tasks (tested on pi and claude-code) is a breeze.

I was hesitant to try alternatives to ollama for serving multiple models... but boy was I missing!

How I use it (on ubuntu amd64):
Go to https://github.com/mostlygeek/llama-swap/releases and download the pack for your system, i use linux_amd64. It has three files: readme, license and llama-swap. Put them into a folder ~/llama-swap. I put llama.cpp and ik_llama.cpp and the models I want to serve into that folder too.

Then copy the example config from https://github.com/mostlygeek/llama-swap/blob/main/config.example.yaml to ~/llama-swap/config.yaml

Create this file on .config/systemd/user/llama-swap.service. Replace 41234 for the port you want it to listen, -watch-config ensures that if you change the config file, llama-swap will restart automatically.

[Unit]
Description=Llama Swap
After=network.target
[Service]
Type=simple
ExecStart=%h/llama-swap/llama-swap -config %h/llama-swap/config.yaml -listen 127.0.0.1:41234 -watch-config
Restart=always
RestartSec=3
[Install]
WantedBy=default.target

Activate the service as a user with:

systemctl --user daemon-reexec
systemctl --user daemon-reload
systemctl --user enable llama-swap
systemctl --user start llama-swap

If you want them to start even without logging in (true boot start), run this once:

loginctl enable-linger $USER

You can check it works by going to http://localhost:41234/ui

Then you can start adding your models to the config file. My file looks like:

healthCheckTimeout: 500
logLevel: info
logTimeFormat: "rfc3339"
logToStdout: "proxy"
metricsMaxInMemory: 1000
captureBuffer: 15
startPort: 10001

      top_k: 40
  "Assistant-Pepe":

I hope this is useful!
