@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.
