The status page records three critical and several major incidents on the cloud agent between 22 July and 24 September 2026, and no rate limit figures or retry guidance were found in the reviewed documentation.\n\n**OpenAI Codex.** Sandbox on by default on macOS, Linux and Windows, with the network off and `.git` and `.codex` read-only. Pre-1.0 at 0.160.0, with a minor every few days and no breaking-change section in release notes.\n\n## Before you call either\n\n### Devin\n\n1. Use a `cog_` service-user key with the Member role. Legacy `apk_` keys fail against v3 and the MCP server with 401 or 403\n2. Set `max_acu_limit` on every session you create. Usage is metered by the work done and has no published unit rate\n3. Session creation is not idempotent in v3. After a timeout, list sessions by tag before creating again\n4. Enterprise keys and personal access tokens must send `X-Org-Id` to the MCP server. Organisation-scoped keys resolve it automatically\n5. Create scheduled work as an automation. POST to the schedules endpoint returns 403 for migrated organisations since 24 September 2026\n\n### OpenAI Codex\n\n1. Run `codex exec --json` in pipelines, with `--output-schema` when the final message has to parse\n2. Keep the default sandbox. `--yolo` removes both the sandbox and approvals\n3. Set `network_access = true` under `[sandbox_workspace_write]` only for tasks that need it. Network is off by default\n4. Set `[analytics] enabled = false` and `[feedback] enabled = false` in config.toml to keep usage data local\n5. Pin the npm version. A 0.x minor lands every few days\n\n## Questions\n\n### Which is better for AI agents, Devin or OpenAI Codex?\n\nOpenAI Codex scores 73 (BB) on agent readiness against Devin's 55.7 (C), and leads in every scored category.\n\n### Are Devin and OpenAI Codex open source?\n\nNo open-source release is listed for Devin. OpenAI Codex is open source (Apache-2.0 (Codex CLI, its Rust crates and the TypeScript and Python SDKs).
