Overview
- Meta announced Muse Spark 1.1 on Thursday, making the model available in a U.S. public preview through the new Meta Model API.
- The company published pricing that gives new API accounts $20 in free credits then charges $1.25 per million input tokens and $4.25 per million output tokens.
- Meta says Muse Spark 1.1 is optimized for agentic tasks, tool use and coding, and can handle long-running workflows with a 1 million‑token context window.
- The company released internal benchmark results showing Muse Spark 1.1 outperforming Anthropic’s Opus 4.8 and OpenAI’s GPT‑5.5 on several agentic tests, a claim that arrives as competitors also roll out new frontier models.
- Executives framed the launch as a shift from open-source experiments toward monetized, in‑house models to reduce third‑party costs and attract developers with lower prices, a change that could intensify price competition and lower costs for firms that build AI into their products.
