elvis@omarsar0 · XElvis Saravia（DAIR.AI）耗时6个月构建自有的 agent orchestrator（编排器），具备编排、路由、动态工件/工作流、验证器、agent 后端切换、自动化、技能及 MCP 工具等功能。这些能力在本周的 Fable 事件中成为最佳防御。他年初即主张“拥有自己的 agent orchestrator”，反对者认为维护成本高且不可持续，但他认为锁定特定工具或模型供应商损失更大。通过挖掘 agent 会话递归构建和测试新想法（包括自主循环、持续学习/记忆系统），他已无法回到仅提供固定功能的供应商。他强调必须控制成本、决策和上下文管理，否则无法进入递归自我改进 AI 领域。
I spent the last 6 months building my own harness and orchestrator.
I built it to allow me to experiment on the frontier of ideas.
Little did I know that the orchestration， the harness， routing capabilities， dynamic artifacts/workflows， verifiers， ability to switch/route between agent backends， automations， the skills， and the MCP tools would be the absolute best defense for what happened with Fable this week.
The argument folks made when I was talking about "owning the agent orchestrator" at the beginning of the year is that this is just high maintenance， too costly， and is unsustainable. It might still feel like it to many. But there is too much to lose if you decide to lock yourself in with a specific tool or model provider.
