# gemini-embedding-exp

Calls to the model gemini-embedding-exp stopped working on October 30, 2025.

## The error Gemini API returns once gemini-embedding-exp is gone

Once it is closed to new API keys: HTTP 404

```json
{"error":{"code":404,"message":"This model models/gemini-embedding-exp is no longer available to new users. Please update your code to use a newer model for the latest features and improvements.","status":"NOT_FOUND"}}
```

Once it is shut down: HTTP 404

```json
{"error":{"code":404,"message":"models/gemini-embedding-exp is not found for API version v1beta, or is not supported for generateContent. Call ModelService.ListModels to see the list of available models and their supported methods.","status":"NOT_FOUND"}}
```

## What to use instead

Move to gemini-embedding-2, recommended by Google.

Embeddings from another model are not comparable with this one's: vectors the code stores must all be computed again with the new model.
