Hi Vercel team,

I'm trying to deploy a FastAPI backend using TensorFlow 2.21.0 on my free Hobby account.

My deployment fails with this error:

1
Error: Total bundle size (2004.81 MB) exceeds the maximum function size (500 MB).

Project configuration:

• Framework: FastAPI
• Python: 3.12
• Vercel CLI: 62.7.0
• Fluid Compute: Enabled
• Plan: Hobby
• Project root: deploy/mobilenet
• Dependencies include TensorFlow, Keras, FastAPI and Pillow.

I read about the Large Functions beta supporting Python bundles up to 5 GB and automatic enrollment for new projects.

However, my newly created project still enforces the 500 MB limit.

I also tried adding VERCEL_SUPPORT_LARGE_FUNCTIONS=1, but Vercel displayed the value as system-managed and would not let me edit it.

My questions:

1. Is the 5 GB Large Functions beta available on the Hobby plan?
2. If yes, why is my project still limited to 500 MB?
3. Is there a setting or supported configuration required to enable it?
4. Can this be resolved without upgrading to Pro?

I'm working on a personal machine-learning portfolio project and would like to remain on the free plan.

Thanks for your help!
