Pre-1.0 at 0.163.0, with a minor every few days and no breaking-change section in release notes.\n\n**Warp (Warp Agent CLI and the Oz Agent API).** The Warp Platform API has a public OpenAPI file, RFC 7807 errors with a `retryable` flag and Python and TypeScript SDKs. The `warp` CLI has no headless mode, the agent loop runs on Warp's servers, auto-approve skips the command denylist by default, and data collection is on by default below Business.\n\n## Before you call either\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, which has the network off. `--yolo` removes both the sandbox and approvals\n3. Replace `gpt-5.5` with `gpt-6.1-sol` in saved configs, custom agents and scripts under ChatGPT sign-in. GPT-5.5 retired there on 14 October 2026\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### Warp (Warp Agent CLI and the Oz Agent API)\n\n1. For unattended work, call `POST https://app.warp.dev/api/v1/agent/runs` with `Authorization: Bearer $WARP_API_KEY`. The `warp` CLI is interactive only\n2. Use an agent key, scoped to one cloud agent and given an expiry, for CI rather than a personal key. Keys are created in the Oz web app or the Warp app\n3. Set `auto_approve_bypasses_command_denylist = false` under `[agents.warp_agent.other]` before starting `warp --auto-approve`\n4. Read `code` and `retryable` in error bodies. A 429 `resource_unavailable` means capacity is full and the platform retries the task itself\n5. Pin a version with `WARP_TUI_VERSION` at install, or set `general.autoupdate_enabled = false`, because script installs update themselves in the background\n\n## Questions\n\n### Which is better for AI agents, OpenAI Codex or Warp (Warp Agent CLI and the Oz Agent API)?\n\nOpenAI Codex scores 73.4 (BB) on agent readiness against Warp (Warp Agent CLI and the Oz Agent API)'s 59.8 (C), and leads in every scored category.\n\n### Are OpenAI Codex and Warp (Warp Agent CLI and the Oz Agent API) open source?\n\nYes. OpenAI Codex is open source (Apache-2.0 (Codex CLI, its Rust crates and the TypeScript and Python SDKs). Codex cloud is a hosted service under OpenAI's terms). Warp (Warp Agent CLI and the Oz Agent API) is open source (Mixed. The client, including the `warp` and `oz` binaries, is AGPL-3.0 with the `warpui_core` and `warpui` crates under MIT.
