Muse Wonder vs Claude Opus 5.5: API pricing, caching, and inputs
Muse Wonder and Opus 5.5 tie on the half-cached example request. Opus lists batch prices and Wonder doesn't, which matters for overnight work. Wonder accepts text, image, video, audio and PDF input.
At standard rates Muse Wonder and Claude Opus 5.5 list the same input and output prices, $4 and $20 per million tokens, so the headline rows can't settle anything. What separates them is cache reads, batch availability and the input types each accepts. Wonder is a reasoning model for complex agentic tasks and is available through its API only. This page prices a long agent session and an overnight batch job on both, then lists what to check before you switch.

How they differ
Muse Wonder charges $4 per million input tokens, $20 per million output tokens and $0.20 for cache reads. Claude Opus 5.5 charges $4, $20 and $0.20. A request with 100,000 input tokens and 5,000 output tokens costs $0.50 on Wonder and $0.50 on Opus when nothing is cached, or $0.31 and $0.31 with half the input read from cache. Cache reads cost the same on both, so a prefix that gets reused saves the same amount on either side. An agent session of 40 turns, each with 150,000 input tokens, 3,000 output tokens and nearly all of the input cached, costs $5.88 on Wonder and $5.88 on Opus. Opus also bills cache writes, at $5 per million tokens for five minutes and $8 for one hour, and the session figure leaves them out. Batch is the next split. Opus lists batch prices and Wonder doesn't, so a nightly job of 5,000 documents at 20,000 input tokens and 1,500 output tokens each costs $275 on Opus and $550 on Wonder at standard rates. Opus lists no separate long prompt rate. The embedded calculator uses live OpenRouter rates, which can depend on provider routing.
Verdict
When the rate cards are close, let your own tasks decide. The two cost the same at every cache share, so price can't separate them and accepted results per dollar will. Two practical points follow. Wonder is API only with no published weights, so there's no hosting alternative if its price or terms change. And input types can decide the whole thing, since a pipeline that needs audio or video in one request may not have a clean path on a model that lacks them. Check what each accepts before you price anything.
Which should you pick?
Choose Muse Wonder
Pick Wonder when your agent work includes audio, video or PDF input and you'd rather send the files directly than convert them first. It's a reasoning model aimed at complex agentic tasks, with a 1,048,576 token context. It's available only through its API, and no weights are published, so you can't host it yourself. It lists no batch price right now, so overnight work pays the standard rates. Test it on the tasks where your current model needs the most retries.
Muse Wonder on OpenRouterChoose Claude Opus 5.5
Pick Opus when your tested tasks finish with fewer errors or less review on it, or when your stack and evaluations already run on Anthropic's API. Its context window is 1,000,000 tokens. It lists batch prices, which lowers the cost of work that can wait for results. Budget for cache writes at $5 per million tokens for five minutes, because a cache that expires gets billed again when it's rebuilt. Confirm its supported input types on Anthropic's pricing and model pages, since this page doesn't list them.
