LangChain Adds NVIDIA Nemotron 3 Ultra for Faster AI Agents

LangChainLangChain

LangChain announced immediate support for NVIDIA Nemotron 3 Ultra, an open frontier model designed for long-running AI agents. This integration makes the model's 5x faster inference and up to 30% lower cost for complex agentic tasks directly available to developers using the LangChain framework.

LangChain now supports NVIDIA Nemotron 3 Ultra out-of-the-box, a 550B Mixture-of-Experts (MoE) open model. This integration includes Day 0 support for "Deep Agents," enabling advanced autonomous capabilities within the LangChain framework. Nemotron 3 Ultra is NVIDIA's latest model for agents.

Designed for complex, multi-step agentic workflows, Nemotron 3 Ultra delivers up to 5x faster inference (running a trained AI model) and reduces the cost of agentic tasks by up to 30% compared to other open frontier models. This performance boost helps address the computational demands of autonomous AI systems.

Nemotron 3 Ultra can now be integrated directly into LangChain projects, enabling more capable and cost-effective AI agents. This framework support, part of LangChain's role in the Nemotron Coalition, aims to simplify the development and deployment of advanced agentic AI.
