Meta's Muse Wonder: API price and specs

Meta released Muse Wonder on October 12, 2026. It is available now through Meta’s self-serve, pay-per-token API under the model ID muse-wonder-1.0, and Meta labels it a preview. Below are the prices and limits on Meta’s own pages as we read them on October 17, 2026.

Price

Per 1M tokens	Standard price
Input	$4.00
Cached input	$0.20
Output	$20.00

• The price is the same at any prompt length: Meta charges no long-context premium.
• Web search grounding costs $2.50 per 1,000 searches on top.
• Meta’s cheaper Contributor mode, where Meta may train on your content, isn’t offered for Muse Wonder. At the standard price your content isn’t used to train Meta’s models.
• Meta lists no batch price.

Claude Opus 5.5 costs the same: $4 input and $20 output per million tokens. Meta’s other API model, Muse Spark 1.3, costs $1.25 input and $4.25 output. The chart at the end of this post sets Muse Wonder against the highest-priced API model of each maker whose prices we track.

Muse Wonder Full is not on the API

The stronger version, Muse Wonder Full (muse-wonder-full-1.0), has no token price. It comes only with a Muse Code subscription: Power Usage at $50 a month or Maximum Usage at $200 a month.

Leaderboard rank

On the LMArena text leaderboard on October 17, 2026, Muse Wonder (Max) was #2 with a score of 1509 (±11) from 3,247 votes. Allowing for that margin, its rank could be anywhere from 1 to 11. Claude Opus 5.5, at the same price, was #3 with 1508. The Muse Wonder entry is the max-effort setting and has few votes so far, so its rank can still move.

Who can sign up

Anyone 18 or older in a supported country can open an account with an email address or phone number, or with Facebook, Google or GitHub. You add a card and pay for what you use: Meta charges the card when your usage reaches a threshold and on the 1st of each month. Meta publishes no list of countries; it says the API works in “most countries and territories where Meta AI is available and billing is supported”.
