Key point

Vercel's Builds and Functions now support Python 3.13 and 3.14.

Details

Vercel's Builds and Functions has begun supporting Python 3.13 and Python 3.14 in addition to the existing Python 3.12.

Projects that do not specify a separate version currently default to Python 3.12, but the default version is expected to switch to Python 3.14 within the next few months.

To continue using the existing Python 3.12 environment, you must specify an upper version bound in a project manifest file such as pyproject.toml or Pipfile.
