bump pydantic to v2

[jens-create]

Would be it be possible to bump pydantic to v2 as ray [serve] is now compatible with pydantic v2? See Ray PR.

Follow up on issue #423 and PR #429.

Hi @jens-create Thanks for bringing this up! We will definitely consider bumping up the version once they bump up the pydantic version in Ray.

Is there a follow-up on this?

Just an FYI, Ray just released their 2.9.0 version, which adds support for Pydantic >=2.5.0

Hi all,

That would be quite good to upgrade, less and less projects will expect pydantic 1.x so the pin on 1.10 on vllm is a becoming a headache.
