When to Build Your Own Agent Harness | Harrison Chase, LangChain

When to Build Your Own Agent Harness | Harrison Chase, LangChain

Harrison Chase, co-founder of LangChain, delves into the critical role of the 'harness' in LLM agents, explaining how it orchestrates models and context. He covers customizing harnesses with middleware and sub-agents, the trade-offs between off-the-shelf and custom solutions for in- and out-of-distribution tasks, and the importance of evaluations and observability for continuous agent improvement. The discussion culminates in the 'data flywheel' concept and the `LangSmith Engine` for automating agent intelligence through iterative refinement.

AI & Data Science Periodic Tables: How They Work Together

AI & Data Science Periodic Tables: How They Work Together

Aaron Baughman and Martin Keen present a unified framework using "periodic tables" to integrate AI and Data Science. They illustrate how elements like pipelines, embeddings, and RAG combine to build real-world AI applications, using a detailed document Q&A system example. The discussion emphasizes the critical interdependence of data science in grounding AI models and ensuring continuous improvement through an innovative feedback loop.

Why Old GPUs Keep Gaining Value

Why Old GPUs Keep Gaining Value

Steve Hou, Head of Research at Silicon Data, unpacks the data behind the AI compute market, revealing persistent tightness in GPU rentals and rising residual values, despite talk of oversupply. He discusses the methodologies behind their GPU price indices and forward curves, the evolving hardware landscape beyond Nvidia (including AMD, Cerebras, and TPUs), and trends in LLM token economics. The conversation also delves into the complex financial aspects of AI data center buildouts, the rise of specialized models, China's emerging AI hardware ecosystem, and the growing importance of power constraints and distributed AI infrastructure.

Chelsea Finn: This is the State of the Art in Robotics

Chelsea Finn: This is the State of the Art in Robotics

Chelsea Finn, co-founder of Physical Intelligence, discusses the path to building general-purpose robots that operate reliably in the real world. She details how advanced reinforcement learning with human intervention, coupled with multi-scale memory systems, significantly boosts robot autonomy and throughput. Finn argues that robotics is entering its "GPT era," moving from specialized models to powerful, out-of-the-box foundation models like their PIO7, which demonstrates strong compositional generalization across tasks, objects, and robot platforms, matching or exceeding specialist performance without fine-tuning. The talk also covers the unique challenges and opportunities in robotics data, model deployment, and career paths.

RL Environments Explained: How AI Agents Learn Real-World Work | Brendan Foody, Mercor

RL Environments Explained: How AI Agents Learn Real-World Work | Brendan Foody, Mercor

Mercor CEO Brendan Foody elucidates the concept of RL environments, essential for training advanced AI agents. He breaks down their three core components—worlds, apps, and tasks—and details Mercor's evolution from crowdsourced data to expert-driven, "agentic" data. Foody underscores the indispensable role of human experts in defining frontier tasks and creating robust verifiers, exemplified by a real legal RL environment. He shares post-training results demonstrating significant performance gains with modest compute, discusses data pricing and quality, demystifies synthetic data, and explores future directions like ultra-long-horizon tasks and virtual co-workers. The talk emphasizes that data sets are becoming a critical moat for application-layer companies, enabling them to own their intelligence.

The OWASP LLM Top 10 has a few surprises for you

The OWASP LLM Top 10 has a few surprises for you

This podcast episode breaks down the 2026 OWASP LLM Top 10, highlighting a significant rise in concern for 'Excessive Agency' over traditional prompt injection. It explores the discrepancies between practitioner fears and incident data, particularly regarding misinformation, and advocates for viewing security frameworks as tools for operationalization and cyber resilience, not just compliance. The discussion also covers CISA's new SBOM guidance, emphasizing the need to operationalize supply chain data for effective risk reduction, and shares Black Hat 2026 insights on AI agents as a new attack surface, introducing the concept of 'intent collusion' and underscoring the critical need for foundational security principles like least privilege.
