- Subject: Reporting
- Models affected: Muse Wonder, Muse Wonder Full, Muse Spark 1.3
- Context window: one-million-token context window
- Pricing: Muse Wonder runs $4.52 per task on the Intelligence Index, nearly three times more than Muse Spark 1.3 ($1.60). Token pricing has climbed too, with $4 per million input tokens and $20 for output, up from $1.25 and $4.25 for the predecessor.

Meta released two new frontier models, Muse Wonder and Muse Wonder Full, which score 52 and 56 points respectively on the Artificial Analysis Intelligence Index v4.3, up from 48 for their predecessor Muse Spark 1.3. The models show significant gains in agentic coding and autonomous problem-solving, with Muse Wonder Full tying Claude Code with Sonnet 5.5 on the Coding Agents Index at 68 points. However, factual knowledge remains a weak spot, with Muse Wonder Full scoring only 30 points on the AA-Omniscience knowledge test, and API pricing has increased to $4 per million input tokens and $20 per million output tokens for Muse Wonder.

## Evidence

Verbatim from https://the-decoder.com/metas-new-frontier-model-muse-wonder-full-breaks-into-the-ai-top-tier/:

> Muse Wonder Full scores 56 points on the Artificial Analysis Intelligence Index v4.3, while Muse Wonder hits 52. Its predecessor, Muse Spark 1.3 , sat at 48 points, which makes this a significant jump from what was a mid-tier model.
