Meta launches Muse Spark 1.1; opens paid Model API with $1.25/$4.25 per token pricing
Meta released Muse Spark 1.1 on July 9, 2026 alongside public preview of the Meta Model API, marking Meta's first closed-weight, paid frontier model and departure from its open-source Llama philosophy. The multimodal reasoning model targets agentic coding and tool-use workflows, featuring a 1-million-token context window with active memory compaction. Pricing: $1.25 per million input tokens, $4.25 per million output tokens, with $20 in free credits at signup.
Muse Spark 1.1 competes directly with OpenAI's GPT-5.6 and Anthropic's Claude Opus 4.8 on specific benchmarks. On agentic tasks—MCP Atlas, JobBench, Humanity's Last Exam with tools—Meta reports leading numbers (88.1, 54.7, 62.1 respectively vs. Opus 4.8's 48.4, 57.9). On coding (SWE-Bench Pro), Muse Spark 1.1 scores 61.5 vs. Opus 4.8's 69.2—still a strong improvement from the original Muse Spark's 10.0. The model handles text, images, video, PDF, and audio; supports multi-agent orchestration; and can delegate tasks to subagents or act as a subordinate.
Meta CEO Mark Zuckerberg posted on X for the first time in three years to declare: 'Our focus is on delivering strong agentic and multimodal models at very low cost.' For architects: Meta is positioning Muse Spark 1.1 as competitive with Claude Code and Anthropic's tooling on enterprise codebases. The pricing sits between low-cost (GPT-5 mini, Claude Haiku) and premium (Claude Sonnet). Developers should compare latency, context efficiency, and multi-agent delegation capabilities against existing vendors before committing; $20 credits allow sandbox testing before production deployment.
