About
Documents the solo-plus-tools configuration Anthropic used to achieve 49% on SWE-bench Verified. Model: Claude 3.5 Sonnet (upgraded). Tools: Bash (persistent shell) and str_replace_editor (file editing). Design principle: "give as much control as possible to the language model itself, and keep the scaffolding minimal." The model determines its own workflow rather than following strict, discrete transitions. Source: Anthropic research page.
