How to use dcode + Nemotron 3 Ultra

In this video, Alex Olson from the LangChain team sets up dcode (LangChain's open source, model agnostic coding agent) with Nemotron 3 Ultra served through Baseten, then put it to work on a real coding task. Along the way we cover installation, model selection, authenticating LangSmith for full tracing, and the new /goal feature, before closing with a look at how NVIDIA's NemoClaw Deep Agents Blueprint takes this same setup into a secure, governed environment for enterprise use.
