Muse Wonder vs Claude Opus 5.5

Verdict

At the same list prices ($4 in, $20 out and $0.20 cached per million; Anthropic also charges $5 per million for 5-minute cache writes, which Meta does not list), Claude Opus 5.5 is the better buy on published results. It scores higher than Muse Wonder on all six Artificial Analysis benchmarks both have, from the Intelligence Index (57.6 against 52.4) to Humanity's Last Exam (61.4% against 50.1%), and Anthropic's Batch API halves its price, while Meta lists no batch discount. Muse Wonder, still in preview on Meta's API, makes sense for video or audio input or inside Meta's Muse Code.

Verdict based on published prices, limits and benchmarks, not on our own tests.

Choose Muse Wonder if

  • You send video or audio input; Claude Opus 5.5 accepts neither
  • You code in Muse Code, where every plan from $5 a month includes Muse Wonder

Choose Claude Opus 5.5 if

  • You want the higher published scores (66.0 against 63.5 on the Coding Agent Index; 59.6% against 52.0% on Terminal-Bench 4.0)
  • Your work is knowledge work (1866 against 1770 Elo on GDPval-AA)
  • You run batch jobs, since the Batch API costs half
  • You need a published output limit (128,000 tokens; Meta does not publish one for Muse Wonder)

Muse Wonder: Cached-input rates apply when part of a prompt matches a cached prefix. There is no long-context premium. Web search grounding costs $2.50 per 1,000 searches. Meta lists no batch discount, and the discounted Contributor mode is not offered for Muse Wonder on the API.

Claude Opus 5.5: Cache writes cost $5 per million tokens (5-minute cache) or $8 (1-hour cache). The Batch API costs half. There is no long-context surcharge. Fast mode costs $8 in and $40 out.

Worked example: what a month costs

We priced three monthly workloads at the standard rates. The provider does not publish these figures.

Standard API prices, no batch or priority discounts. Cached input is billed at the cache-read price; cache-write charges are not included. Reasoning models bill their thinking as output tokens.
