Meta Platforms on Wednesday introduced Muse Code, a new developer tool powered by its latest AI engine, Muse Spark 1.2. The company said the product is intended to assist developers with writing and debugging software and has been optimized to handle extended, complex coding efforts.
Meta described Muse Code as capable of producing code and verifying outcomes. The company said the tool has been trained to take on long-running projects and to coordinate multiple concurrent sub-agents to accelerate the resolution of difficult tasks. Meta added that Muse Spark 1.2 and Muse Code were trained together so they operate as an integrated pair.
The company launched Muse Code in beta and highlighted a continuity feature: the tool keeps a log of its actions. That log allows Muse Code to resume work from its last point if a crash occurs rather than restarting the entire process, Meta said.
Access for developers is via a pay-as-you-go plan. Meta listed the standard tier at $1.25 per million input tokens and $4.25 per million output tokens. The pricing model applies to usage of Muse Code as provided at launch.
Meta noted the release follows an earlier developer testing phase for Muse Spark 1.1, which the company introduced nearly a month prior to this launch. Meta said the previous model, Muse Spark 1.1, was used to generate and evaluate challenging coding problems that contributed to improving Muse Spark 1.2's ability to follow complex instructions.
The introduction of Muse Code places Meta in competition with other AI-driven coding systems, including Anthropic's Claude and OpenAI's Codex, as companies pursue ways to commercialize AI assistant technologies for software development.
Context and implications
By pairing Muse Spark 1.2 with Muse Code, Meta is positioning the two as a combined solution for coding workflows that require both generation and verification across extended tasks. The continuity logging and multi-agent capabilities are presented as features to handle interruptions and parallelize work, respectively. The pay-as-you-go pricing gives developers an on-demand option to access these capabilities.
Summary
- Muse Code, powered by Muse Spark 1.2, is designed for writing, verifying and debugging software.
- The tool supports long, complex projects and can run multiple sub-agents in parallel to speed up difficult tasks.
- Muse Code is available in beta on a pay-as-you-go plan with specified per-million token rates.
