Muse Wonder vs Muse Spark Open
Muse Wonder scores higher on the Models at Work leaderboard (58 vs 54 out of 100). On independent tests alone, Muse Wonder is ahead (64 vs 42). Muse Spark Open has no list price we could verify, so the two cannot be compared on cost. On the Artificial Analysis Intelligence Index, one of the independent tests, Muse Wonder leads 44 to 25.

Choose Muse Wonder for
- Analysis of images and video
- Teams already buying from Meta
Meta charges Claude Opus 5.5's list price for a model that scores 44 on Artificial Analysis's index against Opus's 59: hard to justify unless images and video are the job.
Caveats: Meta's announcement gives no price; $4 in / $20 out per million tokens is the figure Artificial Analysis lists and TechCrunch reported. Level with Opus 5.5 on Scale's visual-reasoning test (43.7 against 44.6) but far behind on its expert-question exam (37.3 against 55.0). On Google's cloud it is labelled preview, which usually means no service guarantee. One user's test run spent $96 without finishing a task that Opus 5.5 finished for $8.44: the same list price is not the same bill. A stronger version, Muse Wonder Full, is sold only inside Meta's Muse Code subscription and is not ranked.
Choose Muse Spark Open for
- Running AI on your own servers or your AWS account
- Keeping sensitive data in-house
Meta's open model for running on your own servers: 25 on Artificial Analysis's index, level with Mistral Large 4, with no per-use price and Meta's own licence to read first.
Caveats: There is no per-use price: you pay for the hardware, and neither Meta nor AWS states what that costs. The licence is Meta's own, with a usage policy, not a standard open licence: have legal read it. It is a very large model that needs data-centre hardware. Meta's own test figures are not counted.
What people running them say
Muse Wonder: The one user report in Signals, from the r/ClaudeAI community on Reddit, is the owner of a model-testing site having it play the video game Pokemon Red: Muse Wonder cost $96.06 over six hours and ended stuck, while Opus 5.5, at the same price per token (the unit vendors bill by), won the game's first gym battle for $8.44. One uncontrolled run, so unscored.

Scores come from the Models at Work leaderboard: Score is 0 to 100 and computed, not typed. 40% is independent testing (Artificial Analysis, Arena, Scale, Epoch, Vals and others; each test is scaled against the best score on this board, and tests of real work, such as finished freelance projects or professional tasks, count double the exams). 30% is price: the vendor's list price for a typical mix of reading and writing, on a fixed scale from $0.05 to $60 per million tokens, so a model that costs a fifth as much gains real ground. 15% is what people report after running it, from Signals and linked threads. 15% is fit: how much text it can take in at once and where a business can get it (the products and clouds that carry it), with a small credit for open weights. A missing component drops out and the rest are reweighted. A model with no independent test yet is provisional and ranks below every measured one. Within three points is a tie. Vendor-published figures are labelled and never counted. Prices are vendor list prices where published; a typical mix assumes three parts reading to one part writing.
