Update: Vercel Functions now support Node.js and Python deployments with package sizes up to 5GB on Fluid compute through the Large Functions public beta.

The bundle size limit for Vercel Functions using the Python runtime is now 500MB, increasing the maximum uncompressed deployment bundle size from 250MB. (This 500MB limit is the standard path; Large Functions support Python bundles up to 5GB on Fluid compute.)

Learn more in the functions limitations documentation, or deploy FastAPI or Flask on Vercel to get started.
