Upgraded to Pro, and Cursor immediately hit cap!

I’m new to Cursor and having the built in Ai assist me in coding out an Arduino ESP32 project.
The current file is ~3500 lines with ~5 header files. Pretty basic as far as Arduino goes.
I just upgraded to Pro and immediately hit the cap, extended the usage/spend limit and it hit it again after just a couple of prompts.

What is going on?!

Am I using it incorrectly or ??

At this pace it would make way more sense to hire a Pro developer to finalize the code.
I have the Ai set to Agent, using Claude Sonnet 4.

This is a fairly straight forward firmware project.

Any suggestions or input are greatly appreciated!

cursor is really expensive for now. the best way would be to search the web for other ai solutions and compare them. check claude, also check codex. from my experience as a sw/hw engineer i can admit that models below opus 4.6 don’t work with C code very well. but opus 4.6 is really expensive in cursor

@Alex_Void Thanks for the reply and for the suggestion to check out Opus 4.6 - I’ll check it out.

At this point I’m cancelling my Cursor subscription and might move that over to run Opus straight out of Claude.

Otherwise, I should just look for someone to hire to just finalize the code (it’s 99% complete and needs final debug, etc.).

The joys of coding (especially when you’re not a Pro level coder LOL)

Thanks again for the tip!

friendly reminder that you can slot your API keys into Cursor to run them at cost, if preferrable

i will say that Cursor’s plans are ultimately cheaper than doing this, however.

At this point, given I’ve spent the equivalent of 2+ months of Claude Ops 4.6 running the same Ai agent in Cursor for the last 3 days.. I’m done with Cursor until either the pricing, usage or overall value are greatly improved.
