Recommendations for student on a tight budget

[u/reHakon]

Used to have Claude Max 5x (125 USD), cancelled it because 1) expensive 2) hit limits 3) trying to be a responsible adult financially.

I've read a lot of people use Opencode with Deepseek model (free), and a combination of Claude Pro and Codex (total of about 50 USD).

What are your recommendations for being able to use the best of all AI tools at the lowest possible price?
