GPT-5.4 Pro or GPT Audio Mini: which to pick
Neither model has a coding score yet, so the two cannot be ranked on coding.
Pick GPT-5.4 Pro for a larger context window (1.05M against 128K tokens).
No benchmark has tested both yet. GPT-5.4 Pro has results on WeirdML, Epoch Capabilities Index and GPQA Diamond (Epoch AI run); GPT Audio Mini has none yet. Compare them on price and context instead.

Benchmark by benchmark
Every board either model has a result on, a category to a fold; bars are each result on a 0 to 100 scale. Only one model is measured on each, so no row names a leader.
