Muse Spark 1.3
Muse Spark · Released 2026-09-02
Meta's 2 Sep 2026 Muse Spark refresh. Live AA Intelligence Index v4.2 is 53 at max effort. Same AA list as 1.2: $1.25 / $4.25 per 1M tokens, 1M context, text / image / video input. Ships in Muse Code and the Meta Model API.
Current Meta frontier for agentic coding and long-horizon tool use. Prefer sourced AA ledger rows over launch DeepSWE / vendor tables. Vals has no model page as of 5 Sep 2026.

Editor's note
Recorded from Meta's 2 Sep 2026 research-blog launch and the live AA model page (v4.2 max-effort index 53, $1.25 / $4.25, 190.1 t/s, TTFT 18.69s). Vals model URL 404s as of 5 Sep 2026. Meta-reported DeepSWE and efficiency claims (~20% fewer tool calls, ~25% fewer tokens vs 1.2) stay vendor-cited. Editorial depth still needs a desk pass.Benchmark placements
