How to use Meta Muse: step-by-step tutorial
Five to eight steps from the account to a first useful result. Where the official guide names a control, the step uses that name. Where it does not, the step stays general.
- Create a Meta Model API account with your Meta Account.
- Install Muse Code and pick a plan, or generate an API key at dev.meta.ai.
- For existing OpenAI-compatible code, change the base URL and set the model to muse-wonder-1.0.
- Check the Contributor mode setting: Meta says subscriptions default to it, trading more usage for training on your content, and you can turn it off.
- Compare the result with the job you came to do. If a label on the screen differs from this guide, follow the official source linked under the steps.
These steps follow the official guide: Muse Code plans.
