So when does Anthropic recommend Fable 5.2 and Mythos 5.2?
For most coding and knowledge-work tasks, it advises starting with Opus 5.5. Fable and Mythos are best for the most ambitious open-ended technical tasks.
Fable 5.2 can also act as an "Advisor": other models turn to it for advice on harder problems.
It can also be an "Orchestrator" that hands simpler tasks off to smaller models.
