Python 3.13 and 3.14 are now available
By Steven Van ·
Vercel Functions and Builds add Python 3.13 and 3.14 support, with the default set to switch from 3.12 to 3.14 in the coming months.
Vercel's Python runtime now supports Python 3.13 and 3.14 for Builds and Functions, alongside the previously supported Python 3.12.
Projects without a specified Python version still default to 3.12, but Vercel says that default will switch to 3.14 in the coming months. To keep using 3.12 once that happens, set an upper bound in your project's pyproject.toml or Pipfile, as described in the Python runtime documentation.
