text-davinci-003 model deprecated

[DivR15]

Hello, I am building an LLM application that uses Langchain libraries. It was working fine until I tried it today and now I get this error:
openai.NotFoundError: Error code: 404 - {'error': {'message': 'The model text-davinci-003 has been deprecated, learn more here: https://platform.openai.com/docs/deprecations', 'type': 'invalid_request_error', 'param': None, 'code': 'model_not_found'}}

Does anyone know how to fix this or how I can change the model I am using?

OpenAI deprecated text-davinci-003. https://platform.openai.com/docs/deprecations

You can transition into the newer OpenAI chat models -- they'll be cheaper to use and likely similar performance if you're using function calling

@DivR15 Looking at the list of deprecations that OpenAI has published here - https://platform.openai.com/docs/deprecations/instructgpt-models , you would use a new model with the following code:

from langchain.llms import OpenAI
llm = OpenAI(model_name="gpt-3.5-turbo-instruct") 

Hope this helps.
