Introducing Muse Code and Muse Spark 1.2

Blog · Watch/Read

  • Simon Willison frames Meta’s release of Muse Spark 1.2 and Muse Code as further evidence that “long-sequence agentic tool calling” is the most important characteristic for current AI models.
  • Muse Spark 1.2 is a coding-focused update, co-trained with Muse Code, demonstrating improvements in code generation, complex debugging, and handling “long-horizon coding tasks” like whole-repository generation.
  • Meta offers a significantly discounted model ID, muse-spark-1.2-contributor ($0.10/$0.20 per million tokens), for users who agree to let Meta use their data to improve products, a detail Simon added to llm-prices.com.
