Gpt4 is locked behind a pay wall, and there are a lot of companies that offer twicked versions for specific uses for a price.
Considering the server space, filtering, and training this thing takes, asking for some fee is almost a given.
On the other hand you have the HuggingFace models that try to create an open source space for AI and I really hope that goes well!
