Cost

Price per million tokens

No public API price. The weights are published, so the only cost is the hardware you run it on.

Published scores

Benchmarks

Figures published by DeepSeek or taken from a public leaderboard. Row last checked 2026-10.

Every reported test

No published benchmark scores yetIts maker has not published benchmark figures for this model, and nothing has been estimated in their place.

Where these numbers come from

Every score on this page is a published figure, taken from the model's own card, system card, technical report or release post, or from a public leaderboard. CorX Labs did not run these evaluations. Most are self-reported by the lab that built the model, which means they were produced under that lab's own choice of prompt, scaffold and number of attempts — so treat them as a starting point for a shortlist, not as a settled ranking.

A score someone other than the model's maker measured is marked Independent and names its measurer. Those are the stronger numbers on this page — an outside harness has no reason to flatter anyone — and there are not many of them.

Where a figure has not been published, the cell reads Not reported rather than an estimate. Nothing here is inferred, interpolated or guessed. Each model records the month its row was last checked. Full method and caveats.
