You can just go on AWS bedrock and use the thinking claude 3.7. You can tune the output size. I doubt you would spend 200 bucks a month in AWS on bedrock even with daily use of claude.

But I agree with the general point that using the API (with different providers) will have better uptime and that it will almost certainly be cheaper.
I can _easily_ burn $20/hour of credits in Cline/RooCode. Before switching to Cursor, full-time software dev could easily burn $100+/week.
