I haven’t hit the Fable guardrails a single time after substantial usage. And I’m working on a ML project (a game AI).

I don’t doubt people are hitting it… shrugs

It tends to bail occasionally for me once auth-related code comes into play.

Nowadays Codex handles the bulk of the implementation and Fable/Opus on the planning.

Not sure if Anthropic patched it, but early on its release the web UI Fable guardrails will trip if you mention you're a biologist.

I hit it whenever doing anything related to security. Auditing code, probing systems, investigating suspicious user activity, etc.

Yeah same. Multiple 20x max accounts, I typically hit > 50% of the fable usage limit on eace, literally never seen a guardrail. Maybe I’m boring? Maybe they have some kind of account reputation system?

Doesn't it silently downgrade to Opus for ML work?

I hit it once when I asked a question about whether butterflies remember anything from their time as caterpillars. I've never hit it for coding, but I also don't really do much related to security.

I’ve only hit it twice. First time was a code review. Fair.

2nd time was literally me being lazy and telling it to commit and open a PR.

Very strange.
