Summary
Meta released Muse Spark 1.1, a multimodal reasoning model built for agentic work with a 1M-token context window and gains in tool use, computer use, and coding, and opened its first paid Meta Model API in public preview at $1.25 per million input and $4.25 per million output tokens.
What changed
On July 9, 2026 Meta's Superintelligence Labs shipped Muse Spark 1.1 with free consumer access at meta.ai plus a new paid Meta Model API in public preview (with $20 in starter credits), positioning it against GPT-5.5, Claude Opus 4.8, and Gemini 3.1 Pro.
Why it matters
Standing up a metered, paid developer API is a strategic shift for Meta, whose model distribution has centered on open weights; charging for a hosted frontier-tier agentic model puts it directly into the commercial API market against OpenAI, Anthropic, and Google. Aggressive per-token pricing targets developers building agents and computer-use workflows.
