17 GPT 5.4 vs GPT 5.2 Which is Stronger First the conclusion, although GPT 5.2 is already good enough, this GPT 5.4 is different, some strange places got stronger First let's check my personal ranking board, see the scores: Runner-up, also awesome, shows it's in the same tier as 5.3-codex, clearly far ahead of all others Next focus on differences, first difference is it can output progress of intermediate small tasks in segments, humans don't just watch anxiously Even because it reports diligently, you'll feel GPT 5.4 is faster than previous GPT versions, takes less time. But I actually calculated the time, found not much improvement, it's an illusion from diligent reporting, humans fall for this 😂
