Personally I find its math abilities really high (in the ballpark of gpt4-turbo and claude opus). By math I mean like undergrad math (Calc I, intro algebra)
Most speculations so far are that this is a preview of the latest model from OpenAI. But there's not much supportive evidence other than it identifies as "based on GPT-4" and seems to be at least as good.
Basically just search Twitter for `gpt2-chatbot` to follow the rumour mill, or go to https://chat.lmsys.org/ and choose `gpt2-chatbot` from the dropdown to test it sourself.
