ME AI event: LangChain and TypeSafe AI will host an in-person technical meetup on November 5 in SoMa, San Francisco, focusing on building decision models and their application in agent evaluation. The event will not be live-streamed or recorded and is open only to registered and approved attendees. The three speakers and their topics are as follows: Sydney Runkle, Product Manager at LangChain’s open-source team, will cover decision models and LangGraph, noting that most agents delegate each decision to cutting-edge large models, resulting in slow speeds and high costs; Jev from TypeSafe AI can provide calibrated probabilities for type-specific agent states and introduces a hybrid pattern of “default to low-cost models, invoke cutting-edge models only during anomalies.” Allie Laabs, Founding Developer Evangelist at TypeSafe AI, advocates understanding such models as “System One Models.” LangChain Education Engineer Seán Roche will share real-world testing of Jev as a judge: the team replayed identical agent runs through Deep Agents and LangSmith to Jev, GPT-5.6 Luna, GPT-5.6 Terra, and Claude Sonnet 4.6, comparing accuracy, consistency, latency, and cost. The agenda begins at 18:00 with welcome and refreshments and concludes at 20:30. Hosted by LangChain, which provides a model-agnostic agent framework and LangSmith for testing, deployment, and monitoring—with over 7,000 customers including Nvidia, Bridgewater, LinkedIn, Workday, Harvey, and Rippling.
