Microsoft has the GPT4 weights, ChatGPT will be available in some form regardless of what happens to OpenAI.
They might have the weights, but for some reason the responses from the microsoft chat is much worse quality for me than gpt-4. Even the local 180B falcon I run locally seems to be better in most cases.
If openai goes under, I personally hope they release all the weights, source code and training data to public domain.
What's "the Microsoft chat"? I've got multiple GPT4 models deployed in Azure and I can't see a difference to vanilla OpenAI's responses.
And they just introduced their own AI chips at Ignite.
