Meta has released Muse Spark 1.1, a multimodal reasoning model for agent-based tasks, and is launching its own developer API for the first time at prices that undercut even the previous price leader, Grok 4.5.
Meta Superintelligence Labs has unveiled Muse Spark 1.1, a multimodal reasoning model built for agent-based tasks, coding, computer use, and multimodal understanding. Meta calls it a "significant upgrade" over the original Muse Spark, which shipped in early April 2026. The model is available in "Thinking" mode in the Meta AI app and on meta.ai. Like its predecessor, Muse Spark 1.1 ships without open weights, suggesting Meta has moved on from the open-source Llama strategy that once made it a hero in the AI community.
Alongside the model, Meta is launching a public preview of the new Meta Model API, giving developers direct access for the first time. The move puts Meta squarely in a market previously held by OpenAI, Anthropic, Google, and several Chinese providers. The new image model, Muse Image, isn't available through the API yet.
Multi-agent orchestration aims to speed up complex projects
Meta says Muse Spark 1.1 is trained to orchestrate multi-agent systems. As the main agent, the model gathers context, builds a plan, and delegates execution to parallel subagents. As a subagent, it stays on task and knows when to escalate back. The model generalizes to new native tools, MCP servers, and custom skills without specific training. It actively manages its one-million-token context window, remembering actions, retrieving and compressing information from earlier work without losing critical steps, according to Meta.
