Aug 5 (Reuters) - 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 monetize 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.
