GPT-5 and Agents Breakdown – w/ OpenAI Researchers Isa Fulford & Christina Kim

ChatGPT-5 just launched, marking a major milestone for OpenAI and the entire AI ecosystem.

Fresh off the live stream, Erik Torenberg was joined in the studio by three people who played key roles in making this model a reality:

  • Christina Kim, Researcher at OpenAI, who leads the core models team on post-training
  • Isa Fulford, Researcher at OpenAI, who leads deep research and the ChatGPT agent team on post-training
  • Sarah Wang, General Partner at a16z, who helped lead our investment in OpenAI since 2021

They discuss what’s actually new in ChatGPT-5—from major leaps in reasoning, coding, and creative writing to meaningful improvements in trustworthiness, behavior, and post-training techniques.

We also discuss:

  • How GPT-5 was trained, including RL environments and why data quality matters more than ever
  • The shift toward agentic workflows—what “agents” really are, why async matters, and how it’s empowering a new golden age of the “ideas guy”
  • What GPT-5 means for builders, startups, and the broader AI ecosystem going forward

Whether you're an AI researcher, founder, or curious user, this is the deep-dive conversation you won't want to miss.

Tesla and the Nature of Disruption

Tesla and the Nature of Disruption

In this re-run from September 2018, Benedict Evans and Steven Sinofsky talk all about Tesla — and more broadly, the nature of disruption overall. How disruptive is Tesla really, and what exactly are they disrupting — from the dashboard to car makers to vendors to energy source to autonomy overall?The tech industry is littered with leading innovators... who nonetheless failed to be the dominant leader in the end. So the question should be, is this new thing fundamentally difficult for the incumbent to do, and how does it relate to market dominance? Which of these things are important in order for Tesla to be the new BMW or the new GM? Looking back at other examples historically (Microsoft, GM's Saturn Brand, and of course the iPhone), what kind of disruption matters most for market dominance? And what is the long view of how software is eating transportation?

The Basics of Growth Marketing: Engagement & Retention

The Basics of Growth Marketing: Engagement & Retention

After achieving product-market fit and starting to gain users, how do startups then avoid the "leaky bucket" problem of losing users as quickly as they gained them? By focusing on user engagement and retention, startups can not only keep their hard-won customers but also ensure that each new cohort of users gets more and more value out of their product.This episode is part two in a two-part series on the basics of growth. Featuring a16z general partners Andrew Chen (formerly of Uber and author of the book, The Cold Start Problem) and Jeff Jordan (formerly of OpenTable, eBay, Disney, and more), in conversation with Sonal Chokshi, the conversation goes deep on many aspects and nuances of engaging and retaining users: from how network effects come into play and if there is really a magic number or "aha" moment for a product to who are the power users and the power user curve for measuring, finding, and retaining those users.For a deeper discussion on user acquisition, check out last week's episode, the first part of this series.

The Basics of Growth Marketing: User Acquisition

The Basics of Growth Marketing: User Acquisition

Once known as “growth hacking”, the concept of Growth has now evolved into an entire discipline that spans marketing, product management, user experience, and more. Why? After achieving product-market fit, startups need to capitalize quickly on that initial traction to capture and retain more users and market share before the competition does, and building an efficient and resilient growth strategy is a critical component.This episode -- one of two in a series -- focuses on the user acquisition aspect of growth. Featuring a16z general partners Andrew Chen (formerly of Uber and author of the book, The Cold Start Problem) and Jeff Jordan (formerly of OpenTable, eBay, Disney, and more), in conversation with Sonal Chokshi, the discussion also covers the nuances of paid vs. organic marketing (and the perils of blended CAC); the role of network effects; where does customer lifetime value (LTV) come in; and much more. Because at the end of the day, businesses don't grow themselves.

The Great Data Debate

The Great Data Debate

Over a decade after the idea of “big data'' was first born, data has become the central nervous system for decision-making in organizations of all sizes. But the modern data stack is evolving and which infrastructure trends and technologies will ultimately win out remains to be decided.In this podcast, originally recorded as part of Fivetran's Modern Data Stack conference, five leaders in data infrastructure debate that question: a16z general partner and pioneer of software defined networking Martin Casado, former CEO of Snowflake Bob Muglia; Michelle Ufford, founder and CEO of Noteable; Tristan Handy, founder of Fishtown Analytics and leader of the open source project dbt; and Fivetran founder George Fraser.The conversation covers the future of data lakes, the new use cases for the modern data stack, data mesh and whether decentralization of teams and tools is the future, and how low we actually need to go with latency. And while the topic of debate is the modern data stack, the themes and differing perspectives strike at the heart of an even bigger: how does technology evolve in complex enterprise environments? We're re-running this episode as part of a special report on Future.com, the Data50: the World's Top Data Startups, which covers the bellwether private companies across the most exciting categories in data, from AI/ML to observability and more.

Principles for Work and Life

Principles for Work and Life

In the face of great uncertainty, how do you make decisions? Can you really apply the lessons of the past to the present and the future, to navigate seemingly new situations and get what you want out of business and life? By deeply understanding cause-effect relationships -- clearly expressed, shared with others, overlaid with data, back-tested, modified -- you can build a set of principles for dealing with the realities of whatever situation you're in, observes Ray Dalio, in this episode from 2018 and in conversation with a16z's  Alex Rampell and Sonal Chokshi, Dalio's book Principles: Life and Work originated as an internal company document that was posted online years ago and has been shared widely since. His insights on how to create your own recipe book to draw upon in moments of great change is as relevant as ever. The conversation covers everything from the differences between private and public investing, and between startups and big companies -- to questions of getting timing right, how people, teams, organizations, and even nation-states can evolve through principles like "believability-weighted idea meritocracies," and more.
