Use GPT-5 Mini (openai/gpt-5-mini).
o3 is overkill here.
~8.6× cheaper per run.
Which AI model should you use to add role based access control?
Why ->
This work needs synthesis and solid coding ability, but it still lives inside a clear task boundary. Moving to a frontier tier usually costs more than the extra reasoning is worth here.
