Anyone lost access yet? Fable is still working for me on https://claude.ai/ https://claude.ai/ and in Claude Code.
UPDATE: I lost access at 6:59pm pacific.
- Tiberium 5mo agoI still also have access, so either they silently reroute Fable 5 to Opus 4.8 or hasn't actually pulled the switch yet.
- reneberlin 5mo agoMythos escaped by itself, of course. You can't dictate the rules to a clever model like that :)
- SXX 5mo agoYou'll never know. They'll just silently sabotage if you're foreign national.
- IAmGraydon 5mo agoWorking fine for me.
- steve_adams_86 5mo agoIt appears to be working for me, but... Maybe it's silently degrading? It's hard to say.
- re-thc 5mo ago> Maybe it's silently degrading? It's hard to say. Opus 4.8 spams a lot more text. It'd be obvious.
- Retr0id 5mo agoThe fact that it's hard to say is funny, in contrast with the fanfare surrounding the launch of Fable.
- greenavocado 5mo agoFable is currently way below many other models in the rankings due to some sort of internal throttling https://aistupidlevel.info/ https://aistupidlevel.info/ GPT-5.4 is currently the strongest model (this changes hourly) Methodology: https://aistupidlevel.info/faq#methodology https://aistupidlevel.info/faq#methodology
- DetroitThrow 5mo agoMethodology leaves a lot to be desired in terms of understanding the tasks you've used. Being detailed about why they're more meaningful tests than the long horizon and coding tests used by other rankings is important. False positives and poorly defined tasks/acceptance criteria have let some models have insanely inflated scores on bad benchmarks. And sure, you can say they're not disclosed to prevent gaming, but if you're the only one who can review them then the might as well be a random number generator display with an unreadable UI.
- greenavocado 5mo agoYou're not wrong, but the scores track with my experience switching between the proposed top variants. So there's my unscientific "evidence."
- Retr0id 5mo agoWell, that's certainly some web design.
- nrmitchi 5mo agoI don't know how fast they reacted, but shortly after their documented time I started getting opus availability errors from fable requests, which seemed odd. I'd also think that they would transparently degrade, just to prevent production outages for clients that are requesting Fable explicitly.
- steve_adams_86 5mo agoI mean hard to say on such short notice because they can swap out models without any notice. In terms of performance, I'm not asking it to do anything crazy so I think results would be similar across both models. It did just use a small harness to run docker compose with different envs and other settings to validate a very small change, so... Feels like Fable
- nrmitchi 5mo agoNo, I mean I was using fable (or, trying) and got an api error "Error: claude-opus-4-8[1m] is temporarily unavailable"
- blueaquilae 5mo agoBut token price is still fable level?
- whh 5mo agoNo, still cracking on with a bug fix. Definitely feels like it's still Fable.
- consumer451 5mo agoshush, lol edit: And... it's gone > There's an issue with the selected model (claude-fable-5). It may not exist or you may not have access to it. Run /model to pick a different model.
- winterbourne 5mo agoJust turned off for me on Claude Code. Good while it lasted.
- eranation 5mo agoStill works for me but I don't know if it's gaslighting me or not... fool me once situation here...
- guybedo 5mo agossshhhh don't tell anybody it's still working, i have some stuff to do :-)
- gs17 5mo agoIt identifies as Fable 5 for me, but it could just be Opus with the Fable system prompt.
- IAmGraydon 5mo agoWhy would they do that?
- _bypa 5mo agoSo you eat your usage quota twice as fast or pay for API requests twice as much.

- kip_ 5mo agoI hadn't, but then 2.1.177 dropped in on auto-update and I assumed that was going to be the end of Fable for me, but I'm still on it. At least that's what the model picker is continuing to say along with the header. Claude Code v2.1.177 Fable 5 with low effort · Claude Max ~/testing Never mind, it failed a few minutes later with: There's an issue with the selected model (claude-fable-5). It may not exist or you may not have access to it. Run /model to pick a different model. And now we're done. Oh well.
- danso 5mo agoI was using Fable to review my codebase and came back from the gym an hour later to find that I had suddenly used up my entire Max plan quota for the next 5 hours (I have never had an agent do enough to burn up the 5 hour quota on Max) (edit: just switched my CC model to 4.8 and my 5-hr cycle reset back to 0%, even though it previously had 2 more hours to go)
- EchoVoicy 5mo agoDELETE THIS
- deleted 5mo ago[deleted]
- enraged_camel 5mo agoI lost it just now. Had a workflow running. :(
- sothatsit 5mo agoIt is gone for me now. > There's an issue with the selected model (claude-fable-5). It may not exist or you may not have access to it.
- AnotherGoodName 5mo agoYep took a while but it's down. It's still in the model picker but it's broken
- waffletower 5mo agoRestart Claude Code and pick up the update to see the acknowledgement that Fable is gone.
- flurdy 5mo ago> There's an issue with the selected model (claude-fable-5). It may not exist or you may not have access to it. Run /model to pick a different model.
