04 — Questions

Which should you choose?

Which is better: Muse Wonder, GLM-5.3 or GPT-5.6 Sol?

It is close. Our weighted score puts them within 2 points (Muse Wonder 68/100, GPT-5.6 Sol 66/100, GLM-5.3 63/100), so choose by what matters most for your work: GPT-5.6 Sol for raw capability and GLM-5.3 on price. The score weighs capability 50%, price 25%, inputs & features 15%, context window 10%.

Which is cheaper, Muse Wonder, GLM-5.3 or GPT-5.6 Sol?

GLM-5.3 is cheaper at $1.40 input / $4.40 output per million tokens (official Z.AI API price). Muse Wonder costs $4.00 input / $20.00 output per million tokens (official Meta API price); GPT-5.6 Sol costs $4.00 input / $20.00 output per million tokens (official OpenAI API price). At a typical mix of three input tokens to one output token, that is $2.15 per million tokens for GLM-5.3 versus $8.00 for Muse Wonder (3.7× as much) and $8.00 for GPT-5.6 Sol (3.7× as much).

Which scores higher on benchmarks?

GPT-5.6 Sol scores higher on the Capabilities Index (ECI): GPT-5.6 Sol 162.6 (#12 of 165), Muse Wonder 161.7 (#13 of 165) and GLM-5.3 156.2 (#33 of 165). The confidence ranges of the top two overlap (159.6–166.2 vs 159.2–164.6), so treat the gap as small. On individual benchmarks: FrontierMath Tiers 1–3 — GPT-5.6 Sol 89.1%, Muse Wonder 82.1%, GLM-5.3 68.8%; OTIS Mock AIME 2024–2025 — GPT-5.6 Sol 100%, Muse Wonder 99.4%, GLM-5.3 91.1%.

Which is better for coding?

There are no published SWE-bench Verified results for Muse Wonder, GLM-5.3 and GPT-5.6 Sol yet, so there is no like-for-like coding score. On overall capability, GPT-5.6 Sol leads, which tends to carry over to coding, but test on your own codebase. All three support tool calling for agent workflows.

Which has the bigger context window?

GPT-5.6 Sol and Muse Wonder have the largest context windows (1,050,000 and 1,048,576 tokens), against 1,000,000 for GLM-5.3. Maximum output per response: Muse Wonder up to 131,072, GLM-5.3 up to 131,072, GPT-5.6 Sol up to 128,000 tokens.

Which can read images, PDFs, audio or video?

Muse Wonder accepts text, images, PDFs, audio and video; GLM-5.3 accepts text; GPT-5.6 Sol accepts text, images and PDFs. Muse Wonder handles the widest range of inputs.

Are any of these open source?

GLM-5.3 publishes its weights and can be self-hosted; Muse Wonder and GPT-5.6 Sol is proprietary.

Which is newer?

Muse Wonder is the newest, released Oct 12, 2026. GLM-5.3 came out Aug 14, 2026; GPT-5.6 Sol came out Jul 9, 2026. Knowledge cutoff: GPT-5.6 Sol Feb 16, 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.
