04 — Questions

Which should you choose?

Which is better: GPT-6.1 Sol or Muse Wonder?

GPT-6.1 Sol is the better all-round choice, scoring 72/100 against Muse Wonder (68). It leads on capability and price. Muse Wonder wins on inputs & features. The score weighs capability 50%, price 25%, inputs & features 15%, context window 10%.

Which is cheaper, GPT-6.1 Sol or Muse Wonder?

GPT-6.1 Sol is cheaper at $2.00 input / $10.00 output per million tokens (official OpenAI API price). Muse Wonder costs $4.00 input / $20.00 output per million tokens (official Meta API price). At a typical mix of three input tokens to one output token, that is $4.00 per million tokens for GPT-6.1 Sol versus $8.00 for Muse Wonder (2× as much).

Which scores higher on benchmarks?

GPT-6.1 Sol scores higher on the Capabilities Index (ECI): GPT-6.1 Sol 167.8 (#4 of 165) and Muse Wonder 161.7 (#13 of 165). The confidence ranges of the top two overlap (164.3–172.5 vs 159.2–164.6), so treat the gap as small. On individual benchmarks: FrontierMath Tiers 1–3 — GPT-6.1 Sol 93.7%, Muse Wonder 82.1%; OTIS Mock AIME 2024–2025 — GPT-6.1 Sol 100%, Muse Wonder 99.4%.

Which is better for coding?

There are no published SWE-bench Verified results for GPT-6.1 Sol and Muse Wonder yet, so there is no like-for-like coding score. On overall capability, GPT-6.1 Sol leads, which tends to carry over to coding, but test on your own codebase. Both support tool calling for agent workflows.

Which has the bigger context window?

Their context windows are effectively the same size: GPT-6.1 Sol 1,050,000 and Muse Wonder 1,048,576 tokens. Maximum output per response: GPT-6.1 Sol up to 128,000, Muse Wonder up to 131,072 tokens.

Which can read images, PDFs, audio or video?

GPT-6.1 Sol accepts text, images and PDFs; Muse Wonder accepts text, images, PDFs, audio and video. Muse Wonder handles the widest range of inputs.

Are any of these open source?

No. GPT-6.1 Sol and Muse Wonder are proprietary and only available through APIs and apps.

Which is newer?

Muse Wonder is the newest, released Oct 12, 2026. GPT-6.1 Sol came out Sep 29, 2026. Knowledge cutoff: GPT-6.1 Sol Apr 30, 2026.

How do you decide the winner?

Each model gets a 0–100 score on capability (50%, independent benchmark results); price (25%, blended price per million tokens (3 input : 1 output), log scale); inputs & features (15%, image, PDF, audio and video input, tool calling, structured output and reasoning); context window (10%, maximum tokens per request, log scale). Dimensions missing for any model are dropped and the remaining weights rescaled, so every model is judged on the same evidence. Specs and prices come from public model listings and the labs’ own API pages; capability scores come from independent benchmark runs. Data updated Nov 2, 2026.
