gpt-35-turbo 0613 does not support chat completion

Question

Hi,
I am developing a chat completion bot, and earlier I used gpt-35-turbo 0301 to achieve this and it worked without any trouble. Now I see that only the 0613 model version is available it doesn't support completion API.
What's the alternate now?

FYI - I am using Azure AI Search as the dataset.

Thanks!

Jayesh Nathani Greetings & Welcome to Microsoft Q&A forum! Can you also share the complete error message?

GPT-3.5 Turbo is used with the Chat Completion API. GPT-3.5 Turbo version 0301 can also be used with the Completions API. GPT-3.5 Turbo versions 0613 and 1106 only support the Chat Completions API.

I would suggest you check Learn how to work with the GPT-35-Turbo and GPT-4 models for more details. Consider using "chat completions" instead of "completions" with these recent models.

As documented here Azure OpenAI Service models - Azure OpenAI | Microsoft Learn, the 0613 revision of gpt-35-turbo is only compatible with that newer chat completions operation:  "Completions" is now considered a supported but "legacy" feature for older models--and this is true for platform.openai.com in addition to Azure OpenAI.

If a you want to use the older completions operation instead of chat completions incase if you have already made significant investments into fine-tuning or ChatML prompt engineering, ytou will need to use a supported model/version as described on the matching documentation page here: Azure OpenAI Service legacy models.

Additionally, Models page of Azure OpenAI Studio shows the features supported by the Model as shown in the below screenshot.

Do let me know if that helps or have any other queries.
