Meta announced today that its AI coding tool Muse Code has officially exited Beta testing and introduced multiple new features, including cross-session messaging, workflows, and a “rewind” function in the command-line interface. Meta has also released an SDK developer preview and begun rolling out subscription plans, hoping to make it easier for users to get started.
Meta said that the production version of Muse Code can now handle more complex multi-session, multi-agent engineering tasks and supports more development approaches.
Installing Muse Code on macOS and Linux is very simple. Users only need to run the following command in a terminal:
curl -fsSL https://dev.meta.ai/install.sh | bash
After installation, users can launch the tool with the muse command and sign in with a Meta Model API account. However, Muse Code cannot run if the computer does not meet the compatibility requirements.
With this production update, Muse Code has also added cross-session messaging, allowing different sessions to communicate with each other.
Meta said that when code changes in one session may affect content being developed in another session, the first session can send the other a direct notification. If one session solves an issue that has stalled another, it can also send the answer directly, so users no longer need to manually copy and enter information between multiple terminal windows.
Another new feature is called Workflow, which allows users to coordinate large numbers of sub-agents to work together and resolve complex engineering tasks more quickly.
To use this feature, users only need to ask Muse Code to “use workflows” and set the work intensity to “ultra.” The system will then automatically trigger workflow mode more frequently.
If users want to restore the current session to an earlier point in the conversation history, they can use the Rewind feature by pressing the Esc key twice in succession.
Muse Code only allows users to rewind to system-designated safe points, and users must confirm before any completed work is undone.
Meta has also begun rolling out multiple subscription plans for developers with different usage needs.
The basic plan is called Everyday Usage and costs $5 per month (note: approximately 33.7 yuan at the current exchange rate). It is suitable for ordinary users who want to complete their first projects. The plan provides access to Muse Spark 1.2, with 10 to 50 requests available every 5 hours, including image and video uploads. Users can also use voice mode and access web search.
The High Usage plan costs $15 per month (approximately 101 yuan at the current exchange rate) and is intended for users who need stronger coding capabilities and work on relatively large projects. It includes all the features of the Everyday Usage plan and provides three times its usage allowance, including more Muse Spark 1.2 requests, more user requests, and more multimodal inputs. It also provides access to the latest models.
The top-tier Power Usage plan costs $50 per month (approximately 336.8 yuan at the current exchange rate) and is intended for users who need high-intensity AI coding workflows. It includes all the features of the High Usage plan and provides 10 times the usage allowance of the Everyday Usage plan, including a higher Muse Spark 1.2 allowance and more user requests. It also provides early access to new features and a higher file upload allowance.
