Request custom size instead of fixed 200K

Custom sizes allow developers to customize between cost and complexity

Claude has a fixed 200k context window, you would have to use Gemini 1.5 or 2 API in order to get a larger context size. Anthropic doesn't offer a larger context size for its API, there is the Enterprise plan with 500k context window which requires you to have a minimum of 35 users, cost $60/month and cannot be access thru an API.

More information is needed about which Model and Provider you are wanting to customize the context window for. As pointed out be @JeansBois, We are unable to modify the context window size (well, we can make it smaller if you want) for 3rd party API Providers.
