A Reddit thread discusses Anthropic's claim that Opus 5.5 performs at the level of Fable 5.1 on most work while costing about 40% less to run than Opus 5. The poster argues the "most work" qualifier is doing a lot of lifting, and asks the community in which tasks Fable still clearly wins — or whether everyone has already switched entirely to Opus 5.5.
