### Description

Everything is working fine, but even after updating the file OpenAiGenerator the model is still working on the 4o.

hi @Outlast_Assistenza !! Welcome to our community 🤗

You will need to reindex your data.

For that, this migration guide can help:

> **[Migrate data | Weaviate](https://weaviate.io/developers/weaviate/manage-data/migrate)**
>
> Overview

You will need to create the collection with the new vectorizer/generative configuration, and then copy your data over.

Because the the vectors generated by one model are different from other models, you will need to re vectorizer everything 😬

Let me know if this helps!

THanks!
