Introducing Muse Code and Muse Spark 1.2
Meta launches Muse Code and Muse Spark 1.2, a co-trained coding agent and model pair.
“Muse Spark 1.2 was extensively trained on long-horizon coding tasks, including whole-repository generation, large end-to-end projects, and auto-research.”
Meta released Muse Spark 1.2 and Muse Code, a coding-focused model and agent pair co-trained for long-horizon agentic workflows including whole-repository generation. The release features an unusual dual-pricing model: standard API access at $1.25/$4.25 per million tokens, or a deeply discounted $0.10/$0.20 if users consent to data sharing for product improvement. Simon Willison frames this as further evidence that long-sequence agentic tool calling is now the defining capability race in the LLM space.
