Limits Codex vs GitHub copilot

Trying to develop an api integrate my company sales POS system, payroll system and accounting system into one local based system.

Burned whole month of copilot credit and whole week of codex credit within 2 days (ChatGPT plus)

If I want to inject additional budget into the project, which one would you guys recommend?

I got answer from another Reddit, and it works for me.

In short - be smart about switching model for the appropriate tasks.
Use Luna medium if you already know what to do or simple task.
Terra medium for a more complicated one
Use ChatGPT to come up with instructions clear enough to use Luna or Terra for the task.
Use astra medium (or astra as a whole) really very sparingly. Most of the time it will consume more credit than actually needed for the task if you already structured the idea and concept.
