New Claude model - Fable

Ben's Bites · 1 month ago

Anthropic released Fable, a new Claude model described as a safer version of the unreleased Mythos model, which performs better than Opus 4.8 on benchmarks and is priced at 2x the cost of Opus. Fable is available only until June 22nd in Claude subscription plans before transitioning to paid credits, and the model shows particular strength in spawning multiple subagents while maintaining context. The release sparked controversy over Anthropic's policy to restrict the model's use for ML/AI work, which the company partially walked back after backlash.
