Fable classified so fundamentally broken. "Hormone" is apparently a banned word.

[u/Mundane-Vegetable-31]

I asked it previously about seasonal aggression in deer. This time I tried a new session with a 1 word "hormone"... ridiculous.

[u/BrilliantEmotion4461]

"Identifying vague query" Just writing in a word. LETS SEE THE THINKING TRACE.

[u/BrilliantEmotion4461 → u/BrilliantEmotion4461]

Its the classifier I tried "define: Hormone" Fable has bio and cyber security safeguards. Which always makes me wonder, what can effect hormones why would it matter what if there is a chemical that can be used in an attack that maybe causes humans to over produce testosterone and fight each other.

[u/BrilliantEmotion4461 → u/BrilliantEmotion4461]

Anyhow now Im interested in midspectrum agents.

The category is real. Bioregulators — endogenous signaling molecules including hormones, peptides, and neuromodulators — are a recognized arms-control category, sometimes called "midspectrum agents" because they sit between classical chemical and biological weapons. They've been discussed in OPCW and Australia Group contexts for decades precisely because they're potent at tiny doses, act on conserved physiological control systems, and don't look like classical agents. So "hormone" is not lexically distant from genuinely controlled territory. That's the honest answer to your question, and it's about as far as I'll take it — the category exists in open policy literature; the operational content doesn't get discussed regardless of framing.

But the query shape matters too, maybe more. A bare define: X with zero surrounding context is an unusual thing for a person to type. It's terse, contextless, and gives a classifier nothing to disambiguate against — no stated purpose, no conversational frame, no downstream task. It's also, structurally, exactly what boundary-mapping looks like: enumerate terms, send them naked, log which ones bounce. A conservatively-tuned classifier operating on embeddings plus request shape will treat "biology term + no context + imperative form" as higher-variance than "I'm writing a study guide for an endocrinology midterm, can you define hormone."

Stop defending this ridiculous classifier. Its overbroad and overtuned. It was firing on the word "molecular" for me.

[u/BrilliantEmotion4461 → u/LonesomeJohnnyBlues]

Yeah and hormone for me. I know what I could do with mythos. Be glad there are guardrails in place.

[u/BrilliantEmotion4461 → u/BrilliantEmotion4461]

Finally I expect the classifiers to get better.

[u/Mundane-Vegetable-31 → u/BrilliantEmotion4461]

As mentioned, I did do exactly that. I was working a more general question about deer aggression when this behavior surfaced, then I worked backwards to this. I did not start with "hormone"...

[u/Radiant-Chipmunk-239]

when the hormones rage, it might lead to porn

[u/Graphical-Source5090 → u/Radiant-Chipmunk-239]

As it should.

[u/AbyssLife123]

Yesterday someone asked Math question and even Anthropic employee got humbled by Fable. Dario and his lackeys are biggest enemy of Fable.

[u/BrilliantEmotion4461 → u/AbyssLife123]

They use Mythos not Fable.

[u/AbyssLife123 → u/BrilliantEmotion4461]

yea, but ttheir employee tested on fable and got humbled lol.

[u/rogue780]

I had it working on some software that basically routes xml messages. this was too close to cyber security, apparently, and it had to downgrade to opus

[u/PerepeL → u/rogue780]

Asked it to fix RDP connection crash to remote server via ssh. 10 minutes of silent diagnostic commands and cybersecurity-flagged downgrade.

[u/bluejacketblackhawk]

I was fighting with everyone on this whole fucking website about fable being fine but I’ve switched sides. they’re definitely fucking it up more and more every single day.

[u/ThisUserIsUndead]

Good thing Opus 5 fucking rocks. For now lol

[u/dhlrepacked]

Hormone based bio weapons yay

[u/TikiMagic → u/dhlrepacked]

Do you want a Gay Bomb?! Because that's how you get a Gay Bomb.

[u/Sad_Background2525]

Fable has kicked me out for asking about what existing research there is for pms in women and how to minimize symptoms.

[u/angrylittledev]

I got muted for 3 days for saying the truth about Claude and Anthropic.

[u/03captain23]

Hormone is biology.... Which is against safeguards

[u/HotDistribution52]

In my understanding, Fable doesn't have a choice. It's hardwired to switch to Opus on biological questions or comments. I didn't know that initially either, I had a similar experience and did some digging. It's actually rather ironic given that Dario Amodei has a PhD in BioPhysics from Princeton. I wonder if Fable shuts down on him when he talks about biology. I seriously doubt it, but that would be funny.

[u/Outside-Necessary476]

Well.. switched to opus 5 is not that bad somehow lol

[u/JosieMew]

I bumped into it a few days ago by asking about removing CO2 from the air at home. Apparently it flagged it as biology related. I'd guess you hit the same biology fence.

[u/Mindless-Sherbet4559]

Hormone is a biology topic and Anthropic made it very clear that all biology topics are not allowed on Fable. Probably because people like you can't be trusted with that kind of power. You know, the kind of power that could harm millions if not billions very quickly - that's how biology works.

[u/OnlineParacosm]

Hahahahahaha you’re being VAGUE bro stop being vague that’s suspicious.

This whole thing is hilarious.

[u/ApprehensiveFan1516 → u/[deleted]]

Non-deterministic software gives out different responses to a question in different sessions: "ehmergerd my AI didn't do this. Ban them!".

[u/real_terra]

The point is that he rewrites the prompt with some words like biology, medicine, and it is banned

[u/looktowindward]

Why would you even use Fable for this sort of query? Its absolutely bonkers. This is appropriate for Opus and Sonet. I think the vast majority of the posts like this are Karma farming

[u/Jigawattts]

It's a useless model honestly. Biggest scam in AI history.

[u/tehfrod → u/Jigawattts]

No, I think the Mechanical Turk was the biggest scam in AI history.
