As a result of a US government directive, we are suspending access to Claude Fable 5 for all users. You can continue to use all other Claude models.

Here’s what this means for you:

Across Claude products, new sessions will run on your selected default model or Opus 4.8, and existing Fable 5 sessions will end with an error.

On the Claude Platform, requests to Fable 5 will also return an error. Please update your integrations to other Claude models.

We know this is a disruption to your workflows; we appreciate your patience and support.

No need to panic. IMO, Fable 5 wasn’t worth it for most tasks, not to mention costs and the nerfing.

Opus 4.8 (planning) and GPT-5.5 (execution) still takes the crown.

@omarsar0 Fable 5's quick fade proves that specialized agents beat generalist hype every time, especially on costs.

@yacineMTB I like how they just say “the government” like what agency. Under whose directive. Suspiciously vague

Opus 4.8 can still work on proper planning and Sonnet 4.6 still works really great in execution of you know how to plan its workflows.

Fable 5 really was good, I was using it extensively for past few days for complex execution in CFS systems and on research grounds.

Its not the end of world but its a clap to Consumerism

@omarsar0 The CFO is gonna love this enforced cost saving measure

@CharlesDardaman lol. people just not thinking deep enough on how to leverage combination of models. folks better start to consider it

@yacineMTB Do you think it will be any different with openai? I don't think so

@omarsar0 Can't say I agree - Fable was the ideal team lead for your Opus 4.8 and GPT 5.5 sub-agents

@ConorBronsdon I have been building orchestrator patterns from the get go and I can’t say I will miss Fable.

@yacineMTB anthropic should sell shirts with the mythos weights printed on them

@omarsar0 Would you say that Opus 4.8 is better at planning than Fable 5?

elvis@omarsar0

@ConorBronsdon Super useful, no doubt. But I feel like this model was a bit overhyped from a capability point of view. Just my opinion based on results and my personal setup.

@omarsar0 Why not?

At API billing cost vs. value, sure, I get that - but on a Claude subscription? Super useful.

@omarsar0 100%, people are just running the best model on all tasks rather than benchmarking to see what they actually need. They’ve put 0 thought into it

@yacineMTB It is the same as nuclear weapons, every country should develop their own. You cannot rely on allies when it comes to battle
