The ChatGPT Plus version offers GPT-3.5 Turbo and GPT-4, and I was able to easily find official documentation about them.

So what are the model versions used in the free version of ChatGPT? I see it says text-davinci-002-render-sha, so is that text-davinci-002?

I checked the official ChatGPT documentation and saw different versions of the GPT-3.5 model: (https://platform.openai.com/docs/models/gpt-3-5)

I found that ChatGPT's default mode calls text-davinci-002, but actually leads to the turbo model. (https://github.com/acheong08/ChatGPT/pull/759)
