一个Twitter用户分享了用Fable 5编排Opus和Codex的实战技巧，配置简单，能同时调用多个模型节省成本，适合需要深度推理+代码执行的任务。
该教程介绍如何将 Fable 5（max reasoning 模式）设为主编排器，Opus 专用于深度推理子代理，Sonnet 负责机械任务子代理，Codex 作为同行高级工程师。步骤包括在 Claude Code 中通过 /model 切换模型、用 /agents 创建两个子代理、安装 OpenAI 官方 Codex 插件并配置 /codex:setup。在 CLAUDE.md 中写入编排规则后，用特定提示词指示 Fable 5 像技术负责人一样分配任务。此工作流可节省 Fable 5 的使用次数，同时利用 Opus 和 Codex 并行处理高难度决策。

9. 用 Fable 5 作为 Opus + Codex 的编排器 x.com/diegocabezas01… Diego | AI 🚀 - e/acc @diegocabezas01 Use Fable 5 as orchestrator and Opus + Codex to execute (to save fable usage): Fable 5 (max reasoning) = orchestrator Opus = deep reasoning subagent Sonnet = mechanical work subagent Codex = peer Sr. engineer, different perspective Setup: 1. Set Fable 5 as your main model In Claude Code: /model → Fable 5 → reasoning /effort to max 2. Create 2 subagents with /agents In Claude Code: deep-reasoner → pinned to opus "Use for reasoning-heavy phases, architecture, debugging complex issues, algorithm design. Think thoroughly, return a concise conclusion the orchestrator can act on." fast-worker → pinned to sonnet "Use for mechanical tasks, boilerplate, tests, formatting, simple edits. Execute efficiently." 3. Add OpenAI's official Codex plugin (install codex cli in your computer first), In Claude Code type: /plugin marketplace add openai/codex-plugin-cc /plugin install codex @openai -codex /codex:setup 4. Drop this in your CLAUDE.md in your folder: ## Orchestration workflow You (Fable) are the orchestrator. Plan, decompose, synthesize. Reasoning-heavy phases → deep-reasoner Mechanical work → fast-worker Codex (/codex:rescue --background) is a cracked engineer on par with deep-reasoner, from a different perspective. Treat as a peer, not a reviewer. High-stakes decisions: task Opus + Codex on the same problem in parallel, synthesize the best of both, without showing either the other's answer. Keep your own context lean. 5. Then prompt Fable like a tech lead: "Goal: [what you want] Context: [files, constraints] You're the lead. Delegate reasoning to deep-reasoner, grunt work to fast-worker, fresh-perspective problems to Codex. Show me your plan first, then execute." That's it. 🔗 View Quoted Tweet 💬 1 🔄 0 ❤️ 0 👀 14 📊 1 ⚡
