Meta Releases Muse Spark 1.1 and Opens Low-Cost Meta Model API

Meta is pivoting to selling proprietary agentic AI to undercut rivals on developer cost.

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.
