@Ziyu Zhang Welcome to Microsoft Q&A Forum, Thank you for posting your query here!
I understand that your concern is about the Azure OpenAi gpt4 chat playground is using the model gpt3.
.
Please note that I was also able to reproduce the same issue at my end with GPT4 deployment model and the OpenAI responded saying GPT3 model.
.
We collaborated with the Product Group team and have the below understanding:
- The model deployed in GPT-4 and will remain GPT-4.
- The responses we are getting about GPT-3 is a System Message.
- At the time when the model was initially trained only GPT-3 was available, so the System responds as GPT-3.
- With future model version updates this might change but for now this is expected.
.
Hope this helps. If you have any follow-up questions, please let me know. I would be happy to help.
