Does ChatGPT have an API yet?
GPT has an API.
For example:
curl https://api.openai.com/v1/completions \
-H "Content-Type: application/json" \
-H "Authorization: Bearer $OPENAI_API_KEY" \
-d '{

Not exactly, ChatGPT was fine tuned on top of InstructGPT.
> We trained this model using Reinforcement Learning from Human Feedback (RLHF), using the same methods as InstructGPT, but with slight differences in the data collection setup.
The most up to date LLM is $0.0200/1K tokens (I believe this is tokens returned, approximately 1 word = 1 token, but not quite). I set a billing limit of $50 a month and spent a couple hours playing around this afternoon. It has cost less than $1 so far.
If you go to https://beta.openai.com/account/usage
you will see things like:
text-davinci, 5 requests
187 prompt + 218 completion = 405 tokens
