Muse Spark 1.1

The first upgrade to Meta Superintelligence Labs' Muse Spark line: multimodal reasoning with major gains in tool use, computer use, and coding; 1M-token context (up from 260K); and parallel subagent orchestration. AA Intelligence Index 51 (v4.1, xhigh) — #18 overall, an 8-point jump over the original Spark's 43, drawing even with GPT-5.4. Launched alongside the Meta Model API, Meta's first paid model API ($1.25/$4.25 per MTok, $0.15 cache hits), and Thinking mode in the Meta AI app. Proprietary, like the rest of the Muse line.
