Meta's Muse Wonder Full hits 56 points on Artificial Analysis index

3 Key Points

What happened
Meta released Muse Wonder in two variants. Muse Wonder Full scores 56 points on the Artificial Analysis Intelligence Index v4.3, up from predecessor Muse Spark 1.3's 48 points. On Terminal-Bench 4.0, agentic performance rose from 33 to 57 percent.
Why it matters
The jump from 48 to 56 points moves Meta from a mid-tier position among frontier developers into the top three on six out of ten benchmarks — a recovery for a company that had a weaker stretch with its open models.

WHO IT HITSMeta's API customers and coding-tool users get a two-variant frontier model with sharply better agentic and coding scores, though the higher per-task cost lands on teams running large coding or agent workloads.

Context & Analysis

Meta's release of Muse Wonder in two variants is the company's first frontier model since a stretch in which its open Llama models lost ground to competitors. The benchmark spread tells the story: coding and math improved sharply — Muse Wonder Full solves 94 out of 100 problems on ProofBench, up from 58, and hits 68 points on the Coding Agents Index, tying Claude Code with Sonnet 5.5. But factual knowledge remains thin, with Muse Wonder Full managing only 30 points on the AA-Omniscience test, well behind Claude Opus 5.5, GPT-6 Astra, and Gemini 4 Argon. Low hallucination rates partly compensate; Muse Wonder Full cut its hallucination rate from 33 to 23 percent. On cost, Artificial Analysis puts Muse Wonder at $4.52 per task — below Claude Fable 5.1 and Claude Opus 5.5 but above GPT-6 Astra, Gemini 4 Argon, and GPT-6.1 Sol.
