# gemini-1.5-pro-002

Calls to the model gemini-1.5-pro-002 stopped working on September 29, 2025.

## The error Gemini API returns once gemini-1.5-pro-002 is gone

Once it is closed to new API keys: HTTP 404

```json
{"error":{"code":404,"message":"This model models/gemini-1.5-pro-002 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-1.5-pro-002 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-3.8-flash. gemini-2.5-pro, also named, is closed to some callers (Google: "we are limiting access to the 2.5 models to users who have actively used them in the past." Projects that already called it keep it; new projects are told to use 3.5 Flash-Lite or 3.8 Flash.). Google now limits the 2.5 models to users who already used them, so a project that never called 2.5 Pro cannot move to it; take gemini-3.8-flash instead. 2.5 thinks before answering by default, so budget with thinkingConfig rather than 1.5-era numbers.
