What is Deep Agents? An open source harness for long-running agents. When it comes to agents, the harness is what decides whether it can actually finish long, complex tasks instead of falling apart. An agent is just a model plus a harness. Deep Agents is LangChain's open-source, model-neutral harness. It gives any LLM the context management, tools, memory, subagents, sandboxes, and human-in-the-loop controls it needs to run longer and do more. In this Short, learn how: ✅ The AI harness controls what and when an agent sees ✅ Sandboxes let agents run untrusted code safely ✅ Human-in-the-loop and auth checks gate sensitive actions ✅ The filesystem is swappable across your laptop, a sandbox, or the cloud without changing any code.
