sample 634“GPT-5 mini is my go-to for batch processing. At $0.25/MTok it's hard to beat for simple classification tasks.”
“For well-defined tasks with clear prompts, mini performs almost as well as the full GPT-5 at a fraction of the cost.”
“Mini struggles with ambiguous instructions. Use GPT-5 or Opus for tasks that need interpretation.”
