- A Reddit user asks whether Anthropic/Fable 5 has been throttled or quietly changed, saying performance seems to have dropped sharply in the last week.
- They describe a shift from “extreme thoroughness” to more amateur mistakes, more self-contradiction, and much slower completion on a similar app-building task.
- The post is framed as a community check: others are being asked whether they are seeing the same regression, especially on larger tasks.
