Benchmark leaderboards featuring Claude Sonnet 4
All leaderboardsClaude Sonnet 4: common questions
How much does Claude Sonnet 4 cost per 1M tokens?
No live API price is listed for Claude Sonnet 4 in the current snapshot as of 6 November 2026 because no serving endpoint is published. ModelCap shows a price only when a provider currently lists one.
What is the context window of Claude Sonnet 4?
Claude Sonnet 4 has a published context window of 200K tokens (200,000). The snapshot lists a 64,000 token catalogue-declared route output cap. OpenRouter catalogue or provider-endpoint declaration. Limits can vary by provider and prompt length; a model-wide maximum has not been independently verified. The providers table lists each endpoint's context limit.
Is Claude Sonnet 4 open-weight?
No linked weights. No downloadable model weights are linked in the current source data. This does not identify every API or chat product that offers the model.
Which benchmarks has Claude Sonnet 4 been evaluated on?
Claude Sonnet 4 has published results on 3 public boards tracked by ModelCap as of 6 November 2026: Arena text 1402 (#163 of 419), Arena coding 1474 (#121 of 414) and ARC-AGI-2 5.9% (#179 of 280). Each board page ranks every tracked model on that benchmark. The ModelCap Index scores the results its methodology admits, with published uncertainty, and shows reference boards without scoring them.
When was Claude Sonnet 4 released?
Claude Sonnet 4 first appeared in the catalogue on 22 May 2025, with a published knowledge cutoff of 2025-01-31. It has since been superseded by Claude Sonnet 5.5. Rank and price movements since then are recorded on the site's changes feed.
