Questions people ask
Which is better, GPT-4o or Nova Micro?
GPT-4o wins four of the six areas where both have results: coding, facts, long documents and following instructions. Nova Micro wins none, but costs 99% less. They are level on agents and reasoning.
Which is better for coding?
GPT-4o. It wins 2 of the 2 coding tests both models report; Nova Micro wins none.
Which is cheaper?
GPT-4o costs $5.00 per million input tokens and $15.00 per million output tokens; Nova Micro costs $0.04 and $0.14. That makes Nova Micro about 99% cheaper for the same work.
How do you compare the two?
We use the 27 benchmark tests both models have published scores on. The verdict counts the 11 tests in the eight capability areas, and a gap under one point (ten on rating-style scales) counts as a tie. The other 16 are listed but not counted, because several are summary scores or repeat a test. Each score is the one shown on the model's own page.
