Product docs

  • Codex source coverage is explicit, but plan access, connector permissions, repository policy, and generated-change review should be verified before production use.
  • Codex is the OpenAI and ChatGPT-native delegated coding agent with cloud task, app, IDE extension, CLI, web, GitHub, Slack, Linear, AGENTS.md, permissions, MCP, and automation surfaces. Claude Code is the Anthropic terminal-first coding agent for local developer workflows, MCP, CI, and PR automation.
  • Gemini CLI is best treated as a terminal-first Gemini pilot with explicit auth, quota, sandbox, telemetry, MCP, and shell-command governance. Codex is best treated as a ChatGPT-connected coding agent with web, CLI, IDE, app, GitHub, workspace-control, RBAC, compliance, and usage-limit governance.
  • Use Codex vs Cursor when the buyer is deciding between delegating coding tasks through OpenAI/ChatGPT-native agent surfaces and standardizing an IDE-first AI coding environment for daily repository work.
  • Codex plan availability, agentic usage limits, workspace controls, and data-training behavior should be verified against the buyer's actual ChatGPT plan and workspace settings before a team rollout.
