DSPy 3.4.0 原生支持 Jev 与 System One 模型
如果你在搭 agent 工作流，DSPy 3.4.0 已经原生支持 Jev 这类 System One 模型，还有个新的 ReAnchor 优化器可以试试。
DSPy 发布 3.4.0 版本，新增对 Jev 和 System One 模型的原生支持，可用于兼容的 signatures。该版本还引入名为 ReAnchor 的新优化器，专门用于带置信度校准的输出。dair.ai 的 Omar Khattab 社区作者分享用 Jev 搭建自定义 harness 的实践，在 guardrails、routing 和 verifiers 场景已见成效，并探索工具调用、动态工作流、MCP 加载等更多方向。
Pay attention to System One models if you are building custom harnesses and agentic workflows. Great to see DSPy integrate Jev and now support System One models for calibrating agentic workflows. I'm amazed at how naturally System One models like Jev fit into these frameworks. I am using Jev to build my own custom harnesses like here: academy.dair.ai/resources/jev-… So far, I've had great success with guardrails, routing, and verifiers. However, I am starting to see other interesting applications in other parts of the agent harness, like: > structuring skills and better optimizing them > more efficient tool calling for agents > dynamic workflows (i.e., dynamically generating harnesses with orchestrator + subagents patterns) that leverage Jev-like models for more optimally structuring outputs/information traveling between these workflows > enhance coordination between agents > dynamic and smarter loading (like tools and MCP) of system prompts, and really, all areas of context engineering that benefit from smarter and faster decision-making capabilities > RLM + System One Models And the list goes on and on. Just a wonderful time to explore new ways to work with agents. Isaac Miller 🧩 @isaacbmiller1 DSPy 3.4.0 was just released! This release includes native support for Jev and System one models inside of DSPy! Use it with compatible signatures. This release also includes a brand new optimizer, ReAnchor, specifically for calibrating outputs with confidence. 🔗 View Quoted Tweet 💬 15 🔄 7 ❤️ 49 👀 7591 📊 21 ⚡
