Issue #, if available:
N/A

Description of changes:
Hi😀 Thanks for the useful patterns!

This commit forces the Lambda Python runtime to 3.14, but it seems the update was made without verifying that it actually works.

As a result, I get the following error:

AttributeError: type object 'Runtime' has no attribute 'PYTHON_3_14'. Did you mean: 'PYTHON_3_10'?

So I fixed it.

Check

It works good.

-d '{"prompt": "video of a car made up of fruits"}'
