The error you get
What OpenAI answers a call to davinci-002 once the model is gone, as recorded from real responses:
{"error":{"message":"The model `davinci-002` 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 of davinci-002
Move to gpt-5.6-terra, recommended by OpenAI. Because gpt-5.6-terra is not served on /v1/completions, move the call to Chat Completions (/v1/chat/completions) or the Responses API (/v1/responses), converting the prompt string into messages or input.
