Huggingface more generally, but I'd highlight https://huggingface.co/EleutherAI/gpt-j-6B , the currently largest model, which is almost as good as DaVinci in most respects.
It's not about particular models, though, but the ease of use in numerous cloud or self hosted scenarios. What's the value add for Cohere?
Oh, somehow I've missed that one. Thanks. Agreed about numerous scenarios. Personally I think there is value in managing the models since getting the multiple T/GPUs and setting up REST apis is not trivial. Serverless style GPU rental is a little tricky right now in my experience. But, HuggingFace is doing something similar and the moat isn't too wide.
Oh, and the fact that Cohere is an expensive solution for a problem that's already been solved for free by open source groups.
