Muse Wonder: Meta’s most capable models for personal agents

Muse Wonder is priced at $4.00 per million input tokens, $0.20 for cached input and $20.00 for output, with a 1M-token context window. Muse Wonder Full is not sold by the token. It is limited to developers on Muse Code plans costing $50 or $200 a month. Consumer access to the Muse agent app requires a $20 or $100 monthly subscription, and Meta says Wonder will soon power experiences in Muse, rolling out first to subscribers. Third-party numbers from Artificial Analysis, as relayed by a secondary report, put Wonder Full at 56 on its Intelligence Index and Wonder at 52, against 48 for Muse Spark 1.3. Meta's own model card claims benchmark scores comparable to Fable 5.1 and GPT-6 Astra. Spark was built as a lightweight, low-latency model, while the Wonder models are larger. The models handle text, images, video and audio input and output text. For founders, the split matters more than the benchmarks. The strongest Meta model sits behind a subscription wall, so startups building on the API get the second-tier model. Meta is also testing whether users will pay for agents, which makes it a competitor for consumer agent products and a possible low-cost supplier for developers who want a long-context coding model.
