Model card
Claude Sonnet 5 is the latest model in Anthropic's Sonnet family: the most agentic Sonnet model yet. It can make plans, use tools like browsers and terminals and run autonomously at a level that, only months earlier, required larger and more expensive models. It is an upgrade to Claude Sonnet 4.6, bringing near-Opus intelligence at Sonnet pricing for coding, agents and everyday professional work.
Anthropic's launch materials compare Sonnet 5 against Sonnet 4.6 and the more generally capable Opus 4.8: Sonnet 5 is a strict improvement over Sonnet 4.6 across effort levels and offers a much wider range of cost-performance options, matching Opus 4.8's capability on some tasks at higher effort.
Capabilities
- Effort settings: adjustable reasoning effort trades intelligence for speed and cost per task. Sonnet 5 is substantially more cost-efficient at medium effort than its predecessor.
- Long context: a 1M-token context window.
- Multimodal input: text and image input, with text output.
- Tool use and agents: plans, browses, runs terminals and works autonomously on multi-step tasks.
- Prompt caching and batch processing: Anthropic advertises up to 90% cost savings with prompt caching and 50% with batch processing on its own API.
Benchmark results
Results reported in the Claude Sonnet 5 system card and Anthropic's launch materials, alongside the two reference models from Anthropic's own comparison.
| Benchmark | Claude Sonnet 5 | Claude Sonnet 4.6 | Claude Opus 4.8 |
|---|---|---|---|
| SWE-bench Verified | 85.2% | 79.6% | 88.6% |
| SWE-bench Pro | 63.2% | 58.1% | 69.2% |
| Terminal-Bench 2.1 | 80.4% | 67.0% | 82.7% |
| FrontierCode 1.1 Main | 38.8% | n/a | n/a |
| Humanity's Last Exam (no tools) | 43.2% | 34.6% | 49.8% |
| Humanity's Last Exam (with tools) | 57.4% | 46.8% | 57.9% |
| BrowseComp (single agent, max effort) | 84.7% | n/a | n/a |
| BrowseComp (multi-agent, max effort) | 86.6% | n/a | n/a |
| OSWorld-Verified (computer use) | 81.2% | 78.5% | 83.4% |
| GDPval-AA v2 (knowledge work) | 1618 Elo | 1395 Elo | 1615 Elo |
| HealthBench Professional | 57.8% | n/a | 56.9% |
| CharXiv Reasoning (with tools) | 88.3% | n/a | n/a |
Notes on the numbers, as reported:
- On Humanity's Last Exam with tools enabled, the gap to Opus 4.8 nearly disappears (57.4% vs 57.9%).
- On GDPval-AA v2, Sonnet 5 is the first Sonnet model to outscore the concurrent Opus flagship on any benchmark in Anthropic's comparison (1618 vs 1615 Elo).
- On OSWorld-Verified, Sonnet 5 at its highest effort lands 2.2 points behind Opus 4.8 and well ahead of Sonnet 4.6.
- Anthropic led the launch with SWE-bench Pro (a deliberately harder, more contamination-resistant variant than the older SWE-bench Verified) where Sonnet 5 improved from 58.1% to 63.2% over Sonnet 4.6.
Safety and evaluations
Anthropic's pre-deployment evaluation of Sonnet 5 is documented in the Claude Sonnet 5 System Card, produced with external experts. Across a broad suite of internal and third-party benchmarks, Anthropic reports clear gains over Claude Sonnet 4.6 in coding, agentic search, multimodal reasoning and professional-task performance, with the model trailing Anthropic's Opus and Mythos-class models in almost all cases. The system card covers capabilities (coding, agentic search, multimodal reasoning, real-world professional tasks, healthcare, multilingual performance and life sciences) alongside alignment and safeguards evaluations in depth.
