Strengths
- ✓ 1,048,576-token window with a 943,718-token output ceiling — the largest output allowance in this hub
- ✓ Reads text, image, video, audio and files: the widest input set here, level with Gemini 3.8 Flash
- ✓ Cached reads at $0.20 per million, a twentieth of the input price, which is what a long agent run spends
Limitations
- ! At $4 / $20 per million it costs the same as Claude Opus 5.5 — the end of Meta's discount pricing, since Muse Spark 1.3 is $1.25 / $4.25
- ! Muse Wonder Full, the stronger model in the same release, is not on OpenRouter: Meta ships it to Muse Code subscribers only
- ! Artificial Analysis scores it 52 on its Intelligence Index against 58 for Claude Opus 5.5 and 53 for GPT-6 Astra (read 2026-10-14); the benchmark table in Meta's launch post is Meta's own

Head-to-head comparisons
Muse Wonder vs Claude Opus 5.5
For the first time a Meta model is not the cheap option, so the decision stops being about price and becomes about what you actually need: Muse Wonder carries a 943,718-token output ceiling and reads video and audio, which Opus 5.5 does not, while Opus 5.5 leads the independent index. If your workload is long outputs or media in, the ceiling and the modalities may matter more than six index points.
