Meta launches new AI coding tool powered by Muse Spark 1.2

Meta Platforms on Wednesday launched Muse Code, a coding tool powered by its latest AI model, Muse Spark 1.2, designed to help developers write and debug software.

The launch highlights the social media giant's push ‌into ⁠AI-powered coding ⁠tools, where it competes with Anthropic's Claude and ​OpenAI's Codex amid a broader race to monetise AI assistants.

Muse ​Code can write code and verify results, and has been trained to handle long, complex ​coding projects while also running ⁠multiple sub-agents ‌simultaneously to speed up difficult tasks, ​the ​company said.


Meta also said it trained ⁠Muse Spark 1.2 and Muse Code together to operate smoothly as a pair.

Launched ​in beta, Muse Code keeps a log of its actions, so it can pick up where it left off after a crash rather than start over, the company said.

Developers ‌can access Muse Code through a pay-as-you-go plan, with the standard tier priced ​at $1.25 per ​million input ⁠tokens and $4.25 per million output tokens.

The launch comes nearly a month after Meta introduced Muse Spark 1.1 for developer testing, with the earlier model used to generate and evaluate difficult coding challenges that helped improve Muse Spark 1.2's ability to follow complex instructions.
