Meta announces the end of Muse Code testing phase, new features such as session communication, workflow and more

📅 2026-09-01

Abstract:

Meta announced that Muse Code is now officially out of beta and launching a number of new features, including cross-session messaging, workflows, and session rollback capabilities in the command line interface. In addition, Meta also provides a developer preview version of the software development kit (SDK) and gradually launches different subscription plans to help users get started more easily.

Meta stated that the stable version of Muse Code can handle more complex multi-session and multi-agent engineering tasks and supports more development methods. Currently, macOS and Linux users can install Muse Code by running the following command through the terminal:

curl -fsSL https://dev.meta.ai/install.sh | bash

After the installation is complete, the user can start the program through the muse command and log in using the Meta Model API account. However, if the computer does not meet the compatibility requirements, Muse Code will not run.

In this stable version update, Muse Code adds a new inter-session messaging function, allowing different sessions to send messages to each other. Meta said that when changes in one session affect what is being built in another session, the former can send warnings; when a session solves a question that another session is waiting for, the answer can also be passed directly, without the user having to repeatedly enter information between different terminals.

Muse Code has also added the Workflow workflow function, allowing users to run teams composed of a large number of sub-agents to solve complex engineering tasks faster. Users simply tell Muse Code "use workflow" and set the workload to "ultra" to automatically trigger the workflow more frequently.

If the user wishes to return to an earlier point in the session history, they can press the Esc key twice to enable the rollback feature. Muse Code only allows users to roll back to safe rollback nodes and will ask for user confirmation before undoing any work.

Muse Code currently offers three subscription plans. The "daily use" plan is $5 per month, suitable for users who publish projects for the first time, and includes access to Muse Spark 1.2; it can send 10 to 50 requests every 5 hours, and supports uploading images and videos; it also provides voice mode and web search functions.

The "Heavy Use" plan is $15 per month and is intended for larger projects that require greater coding capabilities. This plan includes all the features of the daily use plan, with 3 times the usage quota, and provides more usage of Muse Spark 1.2, more user requests, more multi-modal input quota, and access to the latest models.

The "Professional Use" plan is $50 per month and is suitable for difficult projects such as intensive coding workflows. This plan includes all the functions of the high-intensity usage plan, with the usage quota increased to 10 times that of the daily usage plan, and further expands the usage and user request quota of Muse Spark 1.2. It also provides early access to new features and a higher file upload quota.
