Dear team, can you increase the capacity of the project? Can you add a paid plan, or increase the capacity plan, so that we can have a deeper chat with the project, the current project capacity is too small, and I would like to ask you, your claude 3.5 sonnet is the version of October 22, and why o1-preview can only be used 10 times a day, which is very limited, can you improve it? Can you import the API key of the large model provider for paid users? Thank you very much for your work, and best wishes.
