@jess_weng18Beyond Simple Agents: Building with LangChain Deep Agents
A lightning lesson with The Gen Academy. Covers what sets Deep Agents apart, how the harness handles long-running work, managing context with memory and summarization, and delegating to subagents.

In this talk I covered 4 context engineering techniques with the deep agents harness (summarization, subagents, offloading and long-term memory) and how a model-agnostic harness keeps memory intact across models.
