Which machine runs the model you want, how fast, and what it costs. Every figure is a real measurement with a named source and a date.

What should I buy?

Uses measured runs where they exist; unmeasured picks are marked as an estimate. Full ranking on the advisor.

Decode is token generation — the speed you feel while an answer streams. Prefill is prompt processing — the wait before it starts.

How the evidence accumulated

Every measured record, stacked by how well corroborated it is, cumulative by the month the benchmark was run. Estimates are excluded: they are generated rather than measured and carry no date of their own.

Read the shape with care. The taller months are partly a record of which sources have been mined rather than of when the world ran more benchmarks, and a run only enters here once someone finds and verifies it — so the right-hand edge understates recent months and will keep filling in.
