# HLE-Diamond (web+code) leaderboard

Knowledge 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.

Humanity's Last Exam Diamond with web and code tools. Every model the catalog carries a published HLE-Diamond (web+code) value for, ranked by that value.

## Benchmark record

Accuracy on HLE-Diamond with constrained web search, page fetching, and code execution at high reasoning effort.

## HLE-Diamond (web+code) ranking

No model in the catalog has a published HLE-Diamond (web+code) score. The benchmark is defined by Introducing HLE-Diamond, 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.
