Building with NVIDIA Nemotron 3 Ultra and LangChain Deep Agents Code on Baseten

This post details the integration of NVIDIA Nemotron 3 Ultra with LangChain Deep Agents Code (dcode) on Baseten. It demonstrates how model-specific harness profiles, like the one for Nemotron 3 Ultra, can be applied to achieve high agent accuracy without requiring model fine-tuning or changes to serving infrastructure. The setup involves installing LangChain dcode with Baseten support and setting the Baseten API key. A simple agent example is provided to showcase how the agent reads workflow and control documents and generates readiness memos and risk tickets using file-reading and file-writing tools.
