Harrison Chase on better models and the agent stack, 20VC podcast

AILangChain's Harrison Chase joined Harry Stebbings on the 20VC podcast to discuss how better models change what developers build and where value sits in the agent stack. The post links to the full episode on YouTube, and an excerpt from the discussion says LangChain spends about 30% of engineering salary on coding tools, a share that fell over the last two months while token usage rose.

AILangChain's Sydney Runkle recaps a conversation between Harrison Chase and Harry Stebbings on the 20VC podcast, arguing that an agent is a model, context, and harness. She says optimizing context comes first for the highest return, followed by the harness and then the weights. She also says agent accuracy, cost, latency, and security are recurring developer concerns, and that memory remains unsolved.
