I want to recompile a Rust project to be f32 instead of f64.
Am I better off buying 1 month of Codex, Claude, or Antigravity?
I want to have the agent continuesly recompile and fix compile errors on loop until all the bugs from switching to f32 are gone.
If I'm not mistaken Codex is free until April 2nd with the previous generous rate limits (while paying customers get 2x).
Literally just find and replace
find and replace is step 1 that generates all the compile errors I want it to loop through
I'm wanting to do it on an entire programming language made in rust: https://github.com/uiua-lang/uiua
Because there are no float32 array languages in existence today
Why do you want a float32 array language? Anyway the free glm4.6 model that is opencode defaults to should be fine. Why pay for something to do this.
Doesn't matter which one. All of them can do things like this now, given a good enough feedback loop. Which your problem has.
All of them can do it but Codex has the least frustrating usage limits.
When using it in VSCode? The browser system running its own container seems like it would be the most demanding on their resources. The stand-alone client is Mac-only but I don't know if it makes a difference.
My goal is to do it within the usage I get from a $20 monthly plan.
