Context Engineering Our Way to Long-Horizon Agents: LangChain’s Harrison Chase

Context Engineering Our Way to Long-Horizon Agents: LangChain’s Harrison Chase

Harrison Chase, co-founder of LangChain, explains the evolution of AI agents from early, rigid scaffolding to modern, flexible "harnesses." He argues that "context engineering"—managing what an LLM sees—is the key to building effective long-horizon agents. Chase also explores how agent development differs from traditional software, highlighting the critical role of traces as the new source of truth and memory systems that enable agents to improve themselves over time.

Prompt Engineering for LLMs, PDL, & LangChain in Action

Martin Keen explains the evolution of prompt engineering from an art to a software engineering discipline. He introduces LangChain and Prompt Declaration Language (PDL) as tools to manage the probabilistic nature of LLMs, ensuring reliable, structured JSON output through concepts like contracts, control loops, and observability.

Underwriting Assist - A Multi Agent System // Somya Rai | Maria Zhang // Agents in Production 2025

Maria Zhang, CEO of Palona AI, and Somya Rai, Principal AI Engineer at EXL, discuss the architecture, scaling, memory management, and cost optimization of multi-agent systems in their respective domains of restaurants and insurance. They explore practical challenges, such as real-world bottlenecks and regulatory compliance, and share their technical stacks, including LangGraph, Ray, and NVIDIA platforms, for building robust and efficient agentic solutions.
