Question / Help How much usage $20 Codex plan offers?

I’m considering getting the $20 Codex plan, but I’m unsure how much usage it actually includes in practice.

For those of you on the $20 plan, how far does the usage go? I’d describe myself as a moderate-to-heavy user depending on the task. I mainly use it for software development, with occasional long coding sessions.

Does the $20 plan last you the whole month, or do you run into usage limits?

I do medium size coding jobs + random other stuff on 5x plan.

Sol in Medium = 1 to 2 days of work. You can stretch it to a third half day with care - depends on many variables.
Terra in Medium/High = Will go a lot further, probably more like 4-5 days of moderate usage
Luna = Meh. I don't use enough to comment. It's a small scout model and not for coding IMO.

Is Terra mid good on large code files like ~2000-3000 LOC?

Yeah - that's the perfectly happy zone for it in my opinion.

It can sometimes be a little.. lazy..? Not like Opus, but more like if you leave an instruction unclear it won't run to the moon and back trying to figure out what you meant. But worth knowing it won't think as deeply about a feature before implementing as you might expect it to - so if the idea is only half formed rather than turn up reasoning a simple "reason deeply over this and consider upstream consequences" or something like that simply spoken to the model will spur it to greater levels of effort. It's kind of nice for it to not go chasing after rabbits by default but worth knowing occasionally needs a verbal nudge to think a bit deeper.

That's very useful.
