# curie

Calls to the model curie on OpenAI stopped working on January 4, 2024.

## The error OpenAI returns once curie is gone

HTTP 404

```json
{"error":{"message":"The model `curie` has been deprecated, learn more here: https://platform.openai.com/docs/deprecations","type":"invalid_request_error","param":null,"code":"model_not_found"}}
```

## What to use instead

Move to gpt-5.6-terra. davinci-002, named first, stopped working on 2026-09-28. OpenAI collapsed four sizes into two. There is no curie-sized base model on the platform now.
