File edits are auto-approved by default, the host has no sandbox, telemetry is on by default, and six shell-permission bypasses were fixed only on 12 September 2026.\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 0.163.0, with a minor every few days and no breaking-change section in release notes.\n\n## Before you call either\n\n### Mistral Vibe CLI\n\n1. Pass `--agent` on every `-p` run (`plan` is read-only). The source default is `accept-edits`, the safety docs say auto-approve, and an experiment can switch it to `smart-approve`\n2. Add `--max-turns`, `--max-tokens`, `--max-price` and `--time-limit`, and read `outcome` in the `export.json` that `--output-dir` writes. Exit 3 means a limit or a refusal\n3. Run in a container or behind `--agent-socket` before using `--auto-approve`. Vibe has no sandbox of its own on the host\n4. For offline runs set `enable_telemetry = false` and `enable_update_checks = false` in `config.toml`. The docs' `enable_auto_update` isn't the key the code reads\n5. Use 2.25.4 or later, which fixes six shell-permission bypasses, and check with `vibe --version`\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## Questions\n\n### Which is better for AI agents, Mistral Vibe CLI or OpenAI Codex?\n\nOpenAI Codex scores 73.4 (BB) on agent readiness against Mistral Vibe CLI's 62.9 (B), and leads in 4 of 7 scored categories. Mistral Vibe CLI leads on reliability.\n\n### Are Mistral Vibe CLI and OpenAI Codex open source?\n\nYes. Mistral Vibe CLI is open source (Apache-2.0). 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).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/mistral-vibe-cli-vs-openai-codex.json, and with the fewest tokens: https://www.anchorterminal.com/compare/mistral-vibe-cli-vs-openai-codex.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"mistral-vibe-cli\", \"b\": \"openai-codex\"}`.
