Does anyone know of reliable sources that have written about the architecture of OpenAI's ChatGPT - specifically regarding the following?:
Number of hidden layers
Number of attention heads
Dimensions of its hidden layers
Sequence length in terms of number of tokens
Number of parameters in the version of the model currently free for public preview. My understanding is there are multiple versions of ChatGPT.
Please note: I'm familiar with GPT-3 already. However, I am not certain that ChatGPT's architecture is the same. Open to contrary evidence, if any.
