Where AI products go next: voice, agents, and self-driving software | Tara Sesha and Nan Yu (OpenAI)

A live talk from the Lenny and Friends Summit with OpenAI's Tara Seshan and Nan Yu and host Claire Vo on building AI products when both technology and user expectations change rapidly. Topics include shipping imperfect features (the ChatGPT "toggle"), the 2 to 3 month model-capability horizon, enterprise absorption limits, single versus multi-agent design, platform layering with computer use as a fallback, working with research through evals, direct user relationships, and predictions for voice, proactive agents, and hardware.

The Defender's Window at enterprise scale with Standard Chartered

Matt Weaver from OpenAI and Reuben Athaide from Standard Chartered discuss how the bank uses OpenAI Daybreak to address the shrinking "defenders window" by focusing on contextual AI analysis of attack paths, fostering cross-functional trust, and leveraging AI for proactive, scalable security in a complex global environment.

Latch-Free Index Trees That Scale: Avoiding Thread Switches & Stalls

David Lomet presents latch-free notices as a way to make index trees scale under high contention. Notices let contending threads elect a single winner early, so that the expensive work of consolidating pages, splitting nodes, and merging nodes is done once rather than redundantly, while the notice also guards the state being replaced and routes concurrent updates. The talk covers latch-free basics with CAS, the cost of delta chains, and detailed walkthroughs of consolidation, splits, and merges in the Bw-tree.

How Jev Turns AI Into Software That Gets Things Done

Diogo Almeida, founder of TypeSafe AI, joins a16z's Ben Horowitz and Martin Casado to explore why AI is so capable yet so underused for automation. He argues that coding agents make developers faster without making software better, and introduces Jev, a primitive that embeds probabilistic, intent-aware intelligence inside programs. The conversation covers reliability as the key to programmable AI, the revival of probabilistic software, why SaaS companies are well positioned to benefit, and the long-term goal of technology that can reliably "do what I mean."

The Defender's Window: Cyber security keynote

OpenAI's cyber leadership explains why every organization needs its own 'defense factory' to turn AI-discovered vulnerabilities into verified fixes before attackers exploit them. The session covers the defenders' window, ecosystem responsibilities, GPT-6 Astra's cyber capabilities and safeguards, the Daybreak Red and Blue tiers, Codex Security workflows and CLI scaling, and OpenAI's internal continuous-defense architecture and results.
