Fable 5.1 Is Now Available on Trevize

Fable 5.1 is now available on Trevize through Claude Code. Anthropic’s latest model is built for coding, knowledge work, and long-running problem-solving: it is better at finding root causes, verifying its work, staying readable through multi-step tasks, and producing concise, grounded answers. Anthropic estimates it costs 25% less than Fable 5 for typical token-billed workloads, with savings of up to roughly 45% for highly agentic work through lower cache-read pricing.

Start using Fable 5.1 in Trevize today. We’d love to see what you’re building with it.
