Muse Wonder vs GPT-6 (Astra / Sol)
Last verified: October 28, 2026 · Sources: Artificial Analysis, vendor announcements
Quick verdict
Muse Wonder undercuts GPT-6 Astra by 2.5x on price — $4/$20 vs $10/$50 per 1M tokens — while offering double the default context (~1M vs 500K tokens on GPT-6.1 Sol). GPT-6 remains competitive on capability but has slipped behind Opus 5.5 head-to-head, and OpenAI is now fighting a distribution war as rivals route to Claude. Unless you are locked into the OpenAI ecosystem, Muse Wonder delivers comparable frontier-tier output at less than half the token cost — and Gemini 4 Argon undercuts both.
Side-by-side comparison
| Muse Wonder / Full | GPT-6 (Astra / Sol) | |
|---|---|---|
| Vendor | Meta | OpenAI |
| API input / output (per 1M) | $4 / $20 (2.5x cheaper) | $10 / $50 (Astra) |
| Context window | ~1M tokens | 500K default (GPT-6.1 Sol, no surcharge) |
| AA Intelligence Index v4.3 | 52 (Wonder) / 56 (Full) | Competitive, behind Opus 5.5 head-to-head |
| Position in market | New challenger (Oct 13, 2026) | Established flagship, shrinking alliance position |
| Agent features | Active Memory, Active Focus | OpenAI agent ecosystem |
| Input modalities | Text, image, video, audio, PDF | Multimodal (verify per variant) |
| Avg cost per task | $4.52 | — |

The price story
This is the most lopsided pricing matchup of the October 2026 flagship class. At $10 input / $50 output per 1M tokens, GPT-6 Astra costs 2.5x Muse Wonder for every token processed. For a workload mixing long prompts and long generations, the monthly bill difference is a rounding error away from "one model vs two models" territory. GPT-6.1 Sol's upgrade to a 500K default context (no surcharge) closed some of the context gap, but Muse Wonder still offers ~1M.
The capability story
GPT-6 is still a top-tier model — the gap to Opus 5.5 is "real but not a blowout" per October 2026 assessments. Against Muse Wonder specifically:
- Coding agents: Muse Wonder Full + Muse Code scored 68 on the coding-agent index, tied with Sonnet 5.5 + Claude Code — a strong showing for the newcomer.
- Knowledge depth: Muse Wonder's factual knowledge (AA-Omniscience 30) is its weak spot; treat any fact-heavy task with care regardless of vendor.
- Ecosystem gravity: OpenAI's developer ecosystem and tooling remain the incumbent advantage; the model-war narrative of late 2026 is that OpenAI is fighting an "entry-point war" as major platforms route to Claude instead.
Which should you choose?
| Your situation | Verdict |
|---|---|
| Cost-sensitive API volume | Muse Wonder (or Gemini 4 Argon at $2/$10) |
| Already invested in OpenAI tooling/agents | GPT-6 — switching costs beat token savings |
| Very long documents in context | Muse Wonder (~1M vs 500K) |
| Video/audio/PDF input | Muse Wonder — single-context multimodal input |
| Maximum reasoning quality, any price | Opus 5.5 (see that comparison) |
