NVIDIA 和 LangChain 搞了个开源智能体，用 Nemotron 3 Ultra 跑 Deep Agents，性能比肩闭源但成本只要 4 块多，比最接近的对手便宜 10 倍。搞 AI agent 的值得看看。
NVIDIA AI 与 LangChain 联合推出基于 Nemotron 3 Ultra 的 Deep Agents 开源智能体框架。该 agent 在评测中取得 0.86 聚合分数，推理成本仅 4.48 美元。而性能最接近的闭源模型成本为 43.48 美元，实现了 10 倍的成本降低。框架完全开放可定制，开发者可直接使用。

Excited to see this out in the open. We've been working with @LangChain to tune their Deep Agents harness for Nemotron 3 Ultra. The result is a fully open, customizable agent that delivers frontier performance at a fraction of the cost of leading closed models. LangChain @LangChain We tuned the harness for @NVIDIAAI Nemotron 3 Ultra. Benchmark-leading performance. 10x lower inference costs. ✅ An aggregate score of 0.86 at a cost of $4.48 ✅ The closest-performing model: $43.48 langchain.com/blog/langchain… 🔗 View Quoted Tweet 💬 12 🔄 10 ❤️ 65 👀 6251 📊 16 ⚡
