Benchmark suiteLatest source data: Oct 16, 2026Checked: October 18, 2026

Long context rankings.

A focused page for document-heavy and retrieval-heavy work. The current view uses Docs, Search, and Text Arena signals while HELM Long Context and context-window metadata are prepared as the next data layer.

Context formula

Document skill first, retrieval support second.

The context proxy blends Document Arena, Search Arena, and Text Arena scores. It does not claim a context-window size or true long-context pass rate until a dedicated source row is available.

Long-context proxy

Higher proxy index is better. HELM Long Context is shown as a planned source rather than a hidden assumption.

Benchmark guide

What the scores mean.

A quick reading key for long-context rankings, document-heavy work, retrieval signals, and planned context-window data.

Higher: context proxyHELM feed planned

What does the long-context proxy measure?

The long-context proxy blends Document Arena, Search Arena, and Text Arena scores. It is meant to surface models that appear strong on document-heavy and retrieval-heavy work while dedicated long-context benchmarks are being wired.

Does this measure context window size?

Not yet. Context window size and max output tokens need a reliable source before they become table fields. This ranking focuses on public task performance, not advertised token limits.

Why is HELM Long Context listed as planned?

HELM Long Context is the right benchmark family for more direct long-context evaluation, but it is not mixed into the score until the feed is integrated and matched cleanly to model rows.

How should I read document and search scores?

Document scores point toward long-form reading and file-style tasks. Search scores point toward retrieval-style workflows. Both are useful signals, but neither proves that a model can reliably use every token in a huge context window.
