Note: You can only select or change the machine type if you are a member of an organization using Codespaces and are creating a codespace on a repository owned by that organization.
You can run your codespace on a choice of remote machine, from 2 cores to 32 cores. Each of these has a different level of resources and a different billing tier. For information, see "About billing for Codespaces."
You can choose a machine type either when you create a codespace or you can change the machine type at any time after you've created a codespace.
For information on choosing a machine type when you create a codespace, see "Creating a codespace." For information on changing the machine type within Visual Studio Code, see "Using Codespaces in Visual Studio Code."
In the top right corner of GitHub.com, click your profile photo, then click Your codespaces.
The current machine type for each of your codespaces is displayed.
Click the ellipsis (...) to the right of the codespace you want to modify.
Click Change machine type.
If multiple machine types are available for your codespace, choose the type of machine you want to use.
Note: Your choice of available machine types may be limited by a policy configured for your organization, or by a minimum machine type specification for your repository. For more information, see "Restricting access to machine types" and "Setting a minimum specification for codespace machines."
Click Update codespace.
The change will take effect the next time your codespace restarts.
If you change the machine type of a codespace you are currently using, and you want to apply the changes immediately, you can force the codespace to restart.
At the bottom left of your codespace window, click Codespaces.
From the options that are displayed at the top of the page select Codespaces: Stop Current Codespace.
After the codespace is stopped, click Restart codespace.
