Meta launched Muse Wonder on October 12, about three months after Muse Spark 1.1 opened Meta’s paid Model API. Meta says the Muse Wonder series is strong at personal and professional agent tasks, tops its internal MemoryBench memory test, and, in the Full version, leads coding benchmarks such as DeepSWE and SWE-Marathon.
Its model card lists Fable 5.1 among the comparison models, and Meta’s launch post publishes Fable 5.1 scores alongside its own. Those are strong claims, since Fable 5.1 is one of Anthropic’s top models.
Muse Wonder comes in two versions. The standard model is available through the Model API and Muse Code, Meta’s coding agent. A higher-capability version, Muse Wonder Full, is only available inside Muse Code on its top subscription plans.
Muse Wonder is available on Meta’s Model API at $4 per million input tokens and $20 per million output tokens. Anthropic released Claude Fable 5.1 in September; it costs $10 and $50 and is available through the API and Claude’s paid plans. That makes Muse Wonder 60% cheaper per token. Cached input narrows the gap: Meta charges $0.20 per million cached input tokens, against $0.25 for Fable 5.1. If it really performs at Fable’s level, that’s a big saving for teams running agents all day.

1 head-to-head on three hard agentic and memory tasks to see whether it matches Meta’s claims.
