Muse Spark 1.2
Muse Spark 1.2 is Meta’s coding-focused model update designed to power Muse Code and improve software engineering workflows. The model is built for code generation, complex debugging, codebase understanding, long-horizon development tasks, and end-to-end developer workflows. Muse Spark 1.2 was co-trained with Muse Code to improve performance inside the terminal coding agent environment. It supports planning, goal conditioning, context compaction, subagent coordination, and iterative coding workflows across large repositories. The model was trained with expanded coding compute, diverse development environments, self-improvement loops, and long-running engineering tasks. Built for AI developers and software teams, Muse Spark 1.2 helps agents plan, write, validate, debug, and optimize code with greater autonomy.

Muse Code
Muse Code is Meta’s terminal coding agent, powered by Muse Spark 1.2, for handling complex software engineering tasks across large repositories. The agent can plan changes, write code, validate results, and coordinate multiple persistent subagents during development sessions. Muse Code uses async background agents that stay active throughout a session to reduce repeated information gathering and help complete multi-step tasks with less steering. Its runtime uses a local event log that records model calls, tool runs, approvals, and edits so sessions can be replayed and resumed after failures. Muse Code includes bundled skills such as /plan for approval-gated planning, /grill for stress-testing plans, and /goal for working toward completion. Built for AI developers and software teams, Muse Code helps automate coding workflows, long-running engineering tasks, debugging, and repository-level development.

Muse
Muse is an innovative AI model developed by Sudowrite, a Los Angeles-based startup, specifically designed for fiction writers. Unlike general-purpose AI tools, Muse focuses exclusively on crafting narrative-driven prose, offering advanced storytelling capabilities and the ability to generate chapter-length content with a high degree of creativity and coherence. Trained with insights from over 20,000 authors, Muse aims to produce unique, evocative writing free of clichés, embracing the full spectrum of human experience, including complex characters, morally gray scenarios, and vivid descriptions, without filters or forced happy endings. Integrated into Sudowrite’s platform, it serves as a collaborative partner for authors, enhancing their creative process with features like gripping openings, believable dialogue, and substantial text generation, all while maintaining the writer’s individual style.
