Hi, as I also reported at GitHub (openai-php/client project), it would seem that requests made to the GPT-4 model are answered by GPT-3.
If I ask GPT-3.5 from openai chat panel “User
Identify yourself: AI name and version” replies: "I am ChatGPT, an AI language model developed by OpenAI. I am based on the GPT-3.5 architecture. How may I assist you today?”.
If I ask GPT-4 the same thing he replies: “I am ChatGPT, an artificial intelligence developed by OpenAI. Specifically, I am based on the GPT-4 architecture. My purpose is to provide assistance, information, and perform tasks involving natural language understanding and generation. It’s important to note that as of my training cut-off in September 2021, I am unable to access real-time data or learn new information after that date”.
The problem is that when I ask the GPT-4 model with PHP client (openai-php/client) it replies identifying itself as GPT-3. This doesn’t surprise me: because it makes the same mistakes as GPT-3.
