Meta upgrades Muse Spark for long-horizon coding without raising API prices

Meta is upgrading its Muse Spark family with a new model aimed at long-horizon coding tasks and agentic software development while keeping its standard API pricing unchanged, giving development teams access to improved capabilities without paying more per token. The new Muse Spark 1.3 model claims to complete coding tasks using about 25% fewer tokens and 20% fewer tool calls than its predecessor, potentially giving development teams more efficient AI-assisted coding at the same per-token price,
