Meta Ships Its First Coding Agent
7AUG
Meta finally entered the coding-agent race. Muse Code, a terminal agent powered by Muse Spark 1.2, plans, writes, and validates changes across big codebases. It fans work out to parallel sub-agents in isolated worktrees.
Mark Zuckerberg says the beta handles full engineering workflows. Background agents stay alive across a session, so context builds instead of resetting on every task.
Pricing follows the Muse Spark API, about $1.25 per million input tokens. Meta says Spark 1.2 scored 59% on the DeepSWE benchmark, ahead of Grok Build and Gemini Flash.
Claude Code and Codex have owned this category. Meta is late but has distribution and cheap inference. The terminal is now a four-way fight.
