Claude Sonnet 4.6 Official Release: Coding, Computer Use, and Agent Benchmarks
Anthropic's release data positions Sonnet 4.6 as a lower-cost Opus-level candidate: it performs strongly on SWE-bench, OSWorld, OfficeQA, financial agents, and long contexts, but Opus 4.6 is still worth considering for extremely deep reasoning, complex search, and difficult refactoring.

The 1M context window is in beta, and long-context pricing and platform limits may differ.
OSWorld-Verified Independent Review: Claude Sonnet 4.6 Computer Use and GUI Task Deep Analysis
On the standard Ubuntu desktop benchmark suite OSWorld-Verified, Claude Sonnet 4.6 achieved a 72.5% task success rate, nearly matching flagship Opus 4.6 (72.7%), but still shows some visual localization jitter in high-frequency complex dynamic popups and multi-level right-click menu scenarios.
Evidence
Editorial analysis
Boundary
Failure modes concentrated: Main failures concentrate on: 1) minor pixel-level dropdown arrow click offset (about 35% of failures); 2) action racing ahead due to slow asynchronous network loading; 3) software shortcut conflicts not triggered.
Artificial Analysis: Sonnet 4.6 Non-Reasoning Intelligence Index 37
Artificial Analysis places Claude Sonnet 4.6 (Non-reasoning, High Effort) among comparable non-reasoning models at Intelligence Index 37, approximately 46 tok/s, input $3 / output $15 per million tokens, with a stated 1M context; the page also notes this model is deprecated, and the intelligence score no longer represents the latest Sonnet.
