Questions people ask
Which is better, Apodex 1.1 or GPT-5.4 nano?
Apodex 1.1 wins four of the six areas where both have results: agents, reasoning, images and charts and long documents. GPT-5.4 nano wins none, but costs 56% less. They are level on coding and facts.
Which is better for coding?
Neither. They win 1 coding test each of the 2 both models report.
Which is cheaper?
Apodex 1.1 costs $0.30 per million input tokens and $3.00 per million output tokens; GPT-5.4 nano costs $0.20 and $1.25. That makes GPT-5.4 nano about 56% cheaper for the same work.
How do you compare the two?
We use the 17 benchmark tests both models have published scores on. The verdict counts the 13 tests in the eight capability areas, and a gap under one point (ten on rating-style scales) counts as a tie. The other 4 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.
