AI SDK v5 Compatibility Issue

[markacianfrani]

Using the embed and chat models on v5 of the ai sdk is throwing compatibility errors:

Error: Unsupported model version v3 for provider "github-models" and model "gpt-4o-mini". AI SDK 5 only supports models that implement specification version "v2".

Reproducible example: https://stackblitz.com/edit/stackblitz-starters-oyemu4d7?file=index.js (AI Disclosure: entirely generated)

Steps to reproduce:

• Fresh install
• AI sdk at latest (5.0.68)

Suspected root cause: the "beta" tag on the AI SDK deps is pulling the newest V3 stuff at runtime. I thought the issue was on my end because you clearly are implementing the V2 interface. I imagine something just recently changed on the ai sdk beta tag side that broke something.
