Meta Opens a New Door for Agent Builders
Muse Spark 1.1 arrives with a public-preview model API, long context, and an emphasis on orchestrating tool-using agents.
Summary
Muse Spark 1.1 arrives with a public-preview model API, long context, and an emphasis on orchestrating tool-using agents.
Meta introduced Muse Spark 1.1 on July 9 as a multimodal reasoning model aimed at agentic work. The company says the model can plan, delegate across parallel subagents, use computers and tools, and manage a one-million-token context window. More consequential for outside builders, Meta also opened a public preview of its Meta Model API. The performance claims remain Meta's own evaluations, but the API changes the release from a consumer-app update into a developer platform move.
