04 — Questions

Which should you choose?

Which is better: Muse Wonder or GPT-6 Astra?

It is close. Our weighted score puts them within a point (Muse Wonder 68/100, GPT-6 Astra 68/100), so choose by what matters most for your work: GPT-6 Astra for raw capability and Muse Wonder on price. The score weighs capability 50%, price 25%, inputs & features 15%, context window 10%.

Which is cheaper, Muse Wonder or GPT-6 Astra?

Muse Wonder is cheaper at $4.00 input / $20.00 output per million tokens (official Meta API price). GPT-6 Astra costs $10.00 input / $50.00 output per million tokens (official OpenAI API price). At a typical mix of three input tokens to one output token, that is $8.00 per million tokens for Muse Wonder versus $20.00 for GPT-6 Astra (2.5× as much).

Which scores higher on benchmarks?

GPT-6 Astra scores higher on the Capabilities Index (ECI): GPT-6 Astra 169.1 (#1 of 165) and Muse Wonder 161.7 (#13 of 165). Their confidence ranges do not overlap (165.9–174.3 vs 159.2–164.6), so the gap is a real one. On individual benchmarks: FrontierMath Tiers 1–3 — GPT-6 Astra 93.7%, Muse Wonder 82.1%; OTIS Mock AIME 2024–2025 — GPT-6 Astra 100%, Muse Wonder 99.4%.

Which is better for coding?

There are no published SWE-bench Verified results for Muse Wonder and GPT-6 Astra yet, so there is no like-for-like coding score. On overall capability, GPT-6 Astra 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: Muse Wonder 1,048,576 and GPT-6 Astra 1,050,000 tokens. Maximum output per response: Muse Wonder up to 131,072, GPT-6 Astra up to 128,000 tokens.

Which can read images, PDFs, audio or video?

Muse Wonder accepts text, images, PDFs, audio and video; GPT-6 Astra accepts text, images and PDFs. Muse Wonder handles the widest range of inputs.

Are any of these open source?

No. Muse Wonder and GPT-6 Astra are proprietary and only available through APIs and apps.

Which is newer?

Muse Wonder is the newest, released Oct 12, 2026. GPT-6 Astra came out Sep 4, 2026. Knowledge cutoff: GPT-6 Astra 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.
