Three production coding agents, five real tasks measured by time, tokens, and PR quality. No marketing — the actual measurement.
GitHub Copilot Workspace, in technical preview since April 2024, proposes task-oriented development: describe the problem in a GitHub issue and the AI reads the codebase, generates an editable multi-file plan, and implements it. It competes with Cursor Composer, though with more latency; its edge is native integration with PRs, issues, and GitHub history.
GitHub Copilot is a coding assistant from GitHub and OpenAI that suggests code in real time inside the editor, trained on billions of lines of public code. It speeds up repetitive tasks such as tests, boilerplate, and documentation, but its suggestions always need human review before reaching production.
GitHub Copilot is an AI-powered coding assistant that suggests code as you type, built into VS Code, JetBrains, and Neovim. It speeds up repetitive tasks and API exploration, but it also generates plausible code with real errors: studies document security vulnerabilities in a meaningful share of its suggestions, so every suggestion still needs human review.
