Why this number isn't obvious
Unlike most tasks, feedback is output-heavy — detailed comments can be as long as the essay — so output token price matters as much as input. That makes model choice a real trade-off between feedback quality and cost per essay at grading scale.

Frequently asked questions
Does feedback quality justify a stronger model?+
Often yes for substantive writing comments, where a flagship gives more useful, specific feedback. For mechanics-only checks, a cheaper model suffices — the calculator shows the cost gap.
Why is essay feedback output-heavy?+
Good feedback is detailed, so the model writes a lot relative to what it reads. That pushes output token cost up, unlike input-heavy tasks like summarization.
