# CharXiv Extended (Mercor) leaderboard

external benchmark

> Every figure below is reproduced as its upstream source published it: nothing is modelled, estimated, interpolated or converted. `Unavailable` means no source published the value — it is never a zero. Each value carries its evidence state and the date it was observed.

CharXiv Extended — Mercor evaluation. Every model the catalog carries a published CharXiv Extended (Mercor) value for, ranked by that value.

## Benchmark record

## CharXiv Extended (Mercor) ranking

No model in the catalog has a published CharXiv Extended (Mercor) score. The benchmark is defined by CharXiv Extended evaluation results, but the catalog carries no value for it yet. An absent value is shown as absent here rather than as a zero.

Rows are ordered by the value the source published, highest first. The source does not state whether a higher value is the better result, so this document does not either: for a benchmark that measures a rate of failure, read the table from the bottom.
