literally couldn't get a single prompt into fable 5 so far. the safety measures make this model utterly useless for security work. it doesn't matter if it's smart if 100% of your queries go straight into a trashbin.

Many users criticized Anthropic's Fable 5 safety filters for blocking security research prompts and called recent models rubbish or trash, while a few praised older versions or expected better open-source alternatives soon.

@banteg It won't even read my tests nor look at smart contracts. It won't look at TEE code. It won't even touch any of my code because the skill files mention Ghidra

@banteg yeah but 4.7/4.8 are still extremely good at security research. they saw Mythos one shot too many systems in such a way that they're legitimately probably scared so yeah

@banteg It doesn't go to a trashbin, it goes to feed their data

Dunno if they use it for white hating in the back, would be great

@ItsMarcosDiaz @banteg "I never actually did the work or looked at the data — which is exactly what answers your two questions. That's the real audit, and I owe it to you."

4.8. So tiring. This *never* happens with Codex, or Pro.
