Gemini 3.8 Flash leads on the shared-benchmark average
Ahead on 2 of 3 shared benchmarks, averaging 1.2 points higher
Summarised only from the 3 percentage-scale benchmarks scored by every selected model; details are below. A further 1 Elo/rating-scale benchmarks are left out of the average — their scale cannot be added to percentages.
“Best available” takes each model’s highest recorded non-parallel mode per benchmark, so it may combine modes into a virtual configuration that does not exist. Read it with the mode breakdown.

Benchmark-by-benchmark comparison. Changing the thinking mode or tool filters updates the chart and table below.
“Best available” picks the highest non-parallel mode separately for each benchmark. The resulting series can combine several reasoning levels and is not one reproducible runtime configuration. Choose a mode filter to compare like-for-like runs.
