And they've hobble Fable and Opus so hard with their safety guardrails, I ask innocuous questions and tasks and they get flagged so often I gave up on it. I can get all the work I need done in GPT5.5 or 5.6 without the hassle.
I just kept a $20 plan going for use on my phone.
They also made Fable no longer ZDR for businesses which killed tons of demand for it.
I had Fable bail on me because I used the word autopilot on a project. Changed to something unrelated, and off we went.
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
I hit it whenever doing anything related to security. Auditing code, probing systems, investigating suspicious user activity, etc.
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.
Doesn't it silently downgrade to Opus for ML work?
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?
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.
It's less likely to give you pushback if you inject your own AI personality into the prompt.
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.
I found a crash in zsh and Fable refused to work after that.
