Fully local multi-agent systems with LangGraph

Video Description

Following the release of OpenAI's new Agents SDK, we've seen a lot of interest in multi-agent workflows. Here, we discuss two different approaches for multi-agent systems - swarm and supervisor - and showcase two different LangGraph packages that make it easy to implement these approaches. We show that both can be run locally with Qwen2.5-14b (via Ollama), which excels at tool-calling. We also show LangGraph Studio and LangSmith traces to provide debugging and observability into these systems.
