Note: This model is packaged using reverse engineering techniques. It simulates user behavior to obtain official responses from Claude, which are then encapsulated into an API. This is not an API officially provided by Claude.
The Claude 3.5 Sonnet upgrade delivers significant improvements across benchmarks, particularly in coding and agentic tasks. It achieves 49.0% on SWE-bench Verified (up from 33.4%), outperforming all publicly available models, including specialized coding agents. It also excels in tool use, scoring 69.2% in retail and 46.0% in airline domains on TAU-bench. A major innovation is its computer use beta, enabling Claude to navigate UIs, click, type, and automate workflows—though still experimental. Early adopters like Replit and GitLab report 10% better reasoning and efficiency in multi-step coding tasks. Safety remains a priority, with joint testing by US/UK AI Safety Institutes confirming its adherence to ASL-2 risk standards.
