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. 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.
