## 正文

Fable 5.1 looks like a more usable model.

And a potential daily-driver. Time will tell.

IMO, Opus 5 is probably still good enough for most tasks, while Fable 5.1 a more sophisticated coordinator amd verifier.

The bigger and more exciting parts of Fable 5.1 are:

• reduces cost by ~45% on highly agentic ones
• reduces cost by ~25% on typical workloads
• great for scientific reserch workflows
• improved token-efficiency
• better writer/prose
