Devin
Devin is Cognition AI's autonomous SWE agent · first to claim end-to-end ticket-to-PR automation with browser, shell, and editor access.
Devin is Cognition AI's autonomous SWE agent · first to claim end-to-end ticket-to-PR automation with browser, shell, and editor access.
Basic
Devin launched March 2024 from Cognition AI (a stealth startup that raised $196M in early rounds). It runs in a cloud sandbox with its own browser, terminal, and editor. You assign a ticket; Devin plans, edits files, runs tests, and opens a PR. Claimed 13.86% resolve rate on SWE-bench Verified at launch · the first public AI agent to break double digits unassisted.
Deep
Devin pioneered the "agent as cloud employee" pattern. Each Devin session runs in an isolated VM with persistent state · filesystem, browser history, installed packages · so multi-hour tasks survive across runs. Integration with Slack, Jira, GitHub, Linear turned it into the model for later agents (Cursor Background, OpenAI Codex). Pricing is seat-based ($500/month per seat) plus compute overage, targeting enterprise dev teams. Benchmarks improved from 13.86% (March 2024) to ~48% on SWE-bench Verified by 2026.
Expert
Devin's harness combines Claude 3.5/4 as planner with GPT-4o or Claude as executor, routed through Cognition's internal orchestration layer. Each session maintains a "scratchpad" long-term memory plus per-tool short-term context. Browser is a headless Chromium instance; shell is a Linux VM; editor is a custom VSCode fork. Cost per task runs $0.20-$5.00 depending on duration. Cognition acquired Windsurf (formerly Codeium) in 2025, absorbing its IDE product and 200+ engineers. Devin now integrates with Windsurf editor for hybrid human-agent workflows.
Devin reset industry expectations for what "agent" means · moved the conversation from chat UI to autonomous cloud workers.
