Lineage

The sequence follows explicit supersedes links. Each score is estimated for that model; a relative can inform a sparse estimate but never sets a floor, so a newer release can score below an earlier one. Scores and prices remain blank when the corresponding public row or first-party rate is unavailable.

How to read this profile

The visual layer above carries the decisions. These notes preserve the model, ranking, coverage, and family context behind the numbers.

Claude Sonnet 5 ranks #34 of 215 on the public leaderboard with a score of 63.83/100. Its source-verified position is #23 of 81.

Claude Sonnet 5 is a proprietary model with a 1M context window. It uses an explicit reasoning mode, which can improve complex problem solving while adding latency and token use.

Official exact-value snapshot from Anthropic's June 30, 2026 Claude Sonnet 5 launch post and system card, with HLE-Verified and LABBench2 comparison rows from Google's Gemini 3.8 Flash model card. We map exact rows that align with existing keys and keep the two Google comparison results display-only. Cost-performance curves and safety-only measurements remain out of scored fields.

Its explicit predecessor is Claude Sonnet 4.6. 44 of 917 tracked benchmark slots currently have displayable evidence. Missing categories stay blank.

Its strongest eligible category is Agentic at #22, while its lowest eligible position is Knowledge at #43. particularly useful for coding agents, browser research, and computer-use workflows.

Last updated November 13, 2026. Runtime fields remain blank until a sourced snapshot exists.

Deployment options

Self-host and provider-specific paths stay separate from benchmark evidence so operating constraints are visible before a score becomes the whole decision.

Questions

How does Claude Sonnet 5 perform overall in AI benchmarks?

Claude Sonnet 5 ranks #34 out of 215 models on the public BenchAlign leaderboard, with a score of 63.83/100. Its evidence status is Supported, and this profile shows 44 source-displayable benchmark rows. The label describes evidence depth, not a provider quality claim; inspect category rows before choosing a workload.

Is Claude Sonnet 5 good for knowledge and understanding?

Claude Sonnet 5 ranks #43 out of 180 eligible models for knowledge and understanding, with a public category score of 61.8/100. Higher-ranked alternatives are available for workloads where this category decides the choice. Check the underlying rows before treating the aggregate as a workload guarantee.

Is Claude Sonnet 5 good for coding and programming?

Claude Sonnet 5 ranks #40 out of 162 eligible models for coding and programming, with a public category score of 51.7/100. Higher-ranked alternatives are available for workloads where this category decides the choice. Check the underlying rows before treating the aggregate as a workload guarantee.

Is Claude Sonnet 5 good for mathematics?

Claude Sonnet 5 has source-displayable benchmark coverage for mathematics, but the public category table does not assign it a rank there. The individual rows remain available for inspection. A missing category position means the evidence threshold was not met; it does not convert the model's unmeasured work into a zero.

Is Claude Sonnet 5 good for agentic tool use and computer tasks?

Claude Sonnet 5 ranks #22 out of 135 eligible models for agentic tool use and computer tasks, with a public category score of 62.5/100. Higher-ranked alternatives are available for workloads where this category decides the choice. Check the underlying rows before treating the aggregate as a workload guarantee.

Is Claude Sonnet 5 good for multimodal and grounded tasks?

Claude Sonnet 5 ranks #34 out of 67 eligible models for multimodal and grounded tasks, with a public category score of 60.4/100. Higher-ranked alternatives are available for workloads where this category decides the choice. Check the underlying rows before treating the aggregate as a workload guarantee.

Does Claude Sonnet 5 have full benchmark coverage on BenchLM?

No. Claude Sonnet 5 currently has 63 source-displayable rows. The profile exposes published, non-generated evidence and leaves missing categories blank until an exact evaluation is available. Coverage describes how much was measured; it is not a penalty added to an individual benchmark result.

What is the context window size of Claude Sonnet 5?

Claude Sonnet 5 has a documented context window of 1M. That figure is the maximum combined prompt and retained-conversation space reported for this exact model; it is not the maximum output length. The profile keeps output limits separate because providers often publish those limits independently.
