Meta Muse Code Overview: Meta's Terminal Coding Agent
Meta's Multi-Agent Coding Platform
Code Llama, Meta's original 2023 code-generation model, has been succeeded by Muse Code -- a terminal-based, multi-agent coding agent built on Meta's current Muse model family (Muse Spark, Muse Wonder) and accessed via the Meta Model API. In 2026, Muse Code coordinates multiple agents in parallel (workers, reviewers, and computer-use agents) to build, debug, and ship software directly from the command line, with a subscription-based pricing model starting at $5/month.

What Is Meta Muse Code and Why Does It Matter?
Meta Muse Code enters a terminal-agent coding space that also includes tools like OpenCode.
Meta's developer platform is now built around Muse-branded models and tools, replacing the Llama-era branding the old URL still implies. Muse Spark 1.3 is presented as the flagship model, built for long-horizon coding and agentic work, with competitive coding performance, native multimodal perception across video, images, and documents, and availability on Meta Model API and Muse Code. The page also lists Muse Spark 1.2 and 1.1, Muse Glimmer as an open-weight model for local agents on Hugging Face, Muse Image at $0.01 per image, Muse Voice Transcribe, and SAM 3.1 for prompt-based detection, segmentation, and tracking. Distribution and access paths shown include Meta Model API, Muse Code, OpenRouter, Meta AI Connectors, and Muse Connectors. Resources include documentation, cookbooks, videos, blog, GitHub, Llama GitHub, and Hugging Face. The page also promotes a Meta Global AI Developer Hackathon with $1M in prizes and a developer newsletter.
Who Should Use Meta Muse Code?
- Development teams: They can use Muse Code to automate multi-step coding tasks and improve productivity.
- Businesses with in-house development: They can benefit from Muse Code's multi-agent approach to generate and review code in multiple languages, streamlining their development processes.
- Researchers: They can utilize Muse Code for research purposes, exploring its multi-agent capabilities in various programming languages.
- Individual developers: They can use Muse Code to assist with coding tasks, especially when working on projects that require multiple programming languages.
Professional reality: Muse Code is not the right choice for developers who want a free coding assistant or who are not comfortable working from a terminal rather than an IDE.
Meta Muse Code Features That Drive Results
Muse Code: Multi-Agent Coding in Your Terminal
Muse Code is a multi-agent coding tool that runs in your terminal, built specifically for Muse Spark. It installs on Mac and Windows via a single curl command: curl -fsSL https://dev.meta.ai/install.sh | bash. Muse Code is now out of beta with new plans and features designed to help you work faster and smarter.
Run a multi-agent coding workflow directly from your terminal, purpose-built for Muse Spark.
Meta Model API: Direct, Self-Serve Access to Muse Spark
Meta Model API provides direct, self-serve and affordable access to Muse Spark. It is compatible with existing OpenAI SDK clients, so you can point your current client at Meta Model API and get your first working request in under five minutes. Muse Image is also available on Meta Model API at $0.01/image.

Muse Spark 1.3: Built for Long-Horizon Coding and Agentic Work
Muse Spark 1.3 is built for long-horizon coding and agentic work, delivering cleaner code with fewer tokens. It tracks context and prior results, works through messy or conflicting inputs, and asks for input when needed. It is tuned for long-horizon coding workflows with fewer unnecessary turns and cleaner output, and performs competitively with frontier models across several coding evals.
Handle long-horizon coding workflows with cleaner output and fewer unnecessary turns.
Native Multimodal Perception Across Video, Images and Documents
Muse Spark perceives video, images and documents, and its visual reasoning runs through a real execution environment instead of scripted steps. You can feed it a screenshot or a clip and let it build. SAM 3.1 complements this by detecting, segmenting, and tracking objects from a text prompt across image and video.
Feed a screenshot or a clip and let Muse Spark build, with visual reasoning running through a real execution environment.
Muse Glimmer: Open-Weight Model for Always-On Local Agents
Muse Glimmer is built to enable always-on, local agents and is available on Hugging Face. It targets agents that need deep access to your context, such as one that manages your schedule, drafts your replies and organizes your files.
Run always-on local agents with deep access to your context, available on Hugging Face.
OpenRouter and Connectors for Existing Workflows
OpenRouter lets you swap Muse Spark into your existing tools and workflows, similar in spirit to how Hugging Face Hub hosts Muse Glimmer's open weights. Meta AI Connectors and Muse Connectors are also available, and the cookbook includes guides for multi-agent orchestration, agent fan-out into isolated worktrees, computer use, building an autonomous GitHub bot on Meta Model API with Muse Spark and OpenCode, and search grounding for live web access via a single tool in your request.

Real-World Use Cases
For the wider AI coding landscape, see our roundup of the best AI coding tools in 2026.
Long-Horizon Coding Agents
Muse Spark 1.3 is trained for long-horizon, agentic workflows — it tracks context and prior results, works through messy or conflicting inputs, and asks for input when needed. Tuned for long-horizon coding workflows, it produces fewer unnecessary turns and cleaner output, making it a fit for building coding agents or using AI as a development partner. Developers who want a terminal-based multi-agent coding experience can pair it with Muse Code, which is built for Muse Spark on Mac and Windows.
Multi-Agent Orchestration and Fan-Out
Meta's cookbooks walk through standing up a four-profile agentic team that turns a one-line product idea into a working SaaS app, and spinning multiple subagents into isolated worktrees to tackle parallel work without mid-flight collisions. Muse Code delivers multi-agent coding directly in your terminal, built for Muse Spark. Teams already running agentic coding tools such as OpenCode can follow the GitHub agent cookbook, which builds an autonomous GitHub bot on Meta Model API with Muse Spark and OpenCode.
Multimodal Perception and Computer Use
Muse Spark natively perceives video, images and documents, and its visual reasoning runs through a real execution environment instead of scripted steps — feed it a screenshot or a clip and let it build. SAM 3.1 detects, segments, and tracks objects from a text prompt across image and video, while Muse Voice Transcribe handles speech to text with speaker diarization and turn detection. The computer use cookbook gives Muse Spark eyes and a pair of hands so it can build software the way you do.
Self-Serve API Access and Search Grounding
Meta Model API offers direct, self-serve and affordable access to Muse Spark, and the quick start gets your first working request in under five minutes by pointing an existing OpenAI SDK compatible client at the API. Muse Image is available on Meta Model API at $0.01/image — a reasoning model that plans layout before drawing, with anchored composition for consistent edits. Adding a single tool to your request gives the model live access to the web for real-time information through search grounding, and Muse Glimmer is an open-weight model built for always-on local agents, available on Hugging Face.
How to Get Started With Meta Muse Code
For the wider developer tooling landscape, see our guide to the best AI tools for developers in 2026.
Install Muse Code via the one-line command on Mac or Windows (irm https://dev.meta.ai/install.ps1 | iex on Windows).
Sign up for a Muse Code subscription plan (Everyday Usage at $5/month is the entry tier).
Run Muse Code in your terminal, letting its coordinated agents (workers, reviewers, and computer-use agents) build and debug your project.
Review each agent's actions via Muse Code's built-in auditability, then ship the result.
Is Meta Muse Code Worth It in 2026?
Muse Code is worth the investment for developers who want a fast, multi-agent coding workflow directly in their terminal, especially given its low $5/month entry tier and built-in auditability. Its multi-agent architecture (parallel workers and reviewers) and tight integration with Meta's Muse models are real strengths, but it requires a paid subscription from the start -- there is no free coding-agent tier, unlike the original free Code Llama model. Overall, Muse Code is a strong option for developers already comfortable paying for AI coding agents (comparable to Cursor or GitHub Copilot), provided its usage limits fit their workload.
