> **Note:** **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](https://vercel.com/changelog/vercel-functions-can-now-be-up-to-5-gb-in-package-size).

The [bundle size limit](https://vercel.com/docs/functions/limitations#bundle-size-limits) for [Vercel Functions](https://vercel.com/docs/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](https://vercel.com/changelog/vercel-functions-can-now-be-up-to-5-gb-in-package-size) support Python bundles up to 5GB on Fluid compute.)

Learn more in the [functions limitations documentation](https://vercel.com/docs/functions/limitations), or deploy [FastAPI](https://vercel.com/templates/python/fastapi-python-boilerplate) or [Flask](https://vercel.com/templates/python/flask-python-boilerplate) on Vercel to get started.
