Codex · 四面开工的异步编码 agentCodex · The Async Coding Agent on Four Fronts.
Codex 不只是 ChatGPT 里写代码的地方。CLI、IDE 扩展、ChatGPT 应用、云端沙箱、GitHub code review、exec/SDK/定时任务凑在一起,是一个异步编码 agent:你定义活和验收标准,它在你不看着的地方把活干完,交回一个可以审的 diff 或 PR。这本书不列全部功能,只挑覆盖八成场景的两成核心:每一项答清楚「省什么、什么活用、什么时候不如别的工具」。差异点章讲云端 —— 怎么把一批活派进云端沙箱、并行跑、按 PR 收回;书眼是「验收」—— 怎么系统性确认 agent 交回的活真做对了,它直接接上《Agent 实战》。倒数第二章给 Plus / Pro 选型、Sol / Terra / Luna 的分工、credits 与省额度纪律,以及和 Claude Code / Cursor / Copilot / Warp 的边界。Codex isn't only where code gets written inside ChatGPT. The CLI, IDE extension, ChatGPT app, cloud sandboxes, GitHub code review, and exec/SDK/scheduled tasks add up to an async coding agent: you define the work and its acceptance criteria, it finishes the work where you aren't watching, and hands back a reviewable diff or PR. This book doesn't list every feature — it picks the 20% that covers 80% of real work, answering for each: what it saves, when to use it, and when another tool wins. The differentiating chapter covers the cloud — sending a batch of jobs into cloud sandboxes, running them in parallel, collecting them as PRs; the centerpiece is review — systematically confirming the agent's work is actually right, connecting straight into Agent in Practice. The penultimate chapter handles Plus / Pro, routing work across Sol / Terra / Luna, credits and quota discipline, and the boundary with Claude Code / Cursor / Copilot / Warp.
