Meta's Muse Spark 1.1 Ships a 1M-Token Agentic Model Alongside Meta's First Paid Developer API

AIapps·high signal

Meta released Muse Spark 1.1, a 1M-token-context agentic model reported to rival GPT-5.5 and Opus 4.8 on agentic evals, and — notably — launched it with Meta's first-ever paid developer API in public preview, including computer-use capabilities. This marks a strategic pivot from Meta's open-weight-only posture toward a monetized developer platform. For builders it opens a new agentic API option with computer use, though pricing and rate limits are still preview-stage and should be verified before adoption.
