There's an ongoing debate about whether AI scaling laws will hold or hit a wall in the near future. However, what's clear now is today's models already have the power to increase productivity in ways that would have been unimaginable even a few years ago. In this episode of the Lightcone, we dig into the results of a recent o1 hackathon hosted by YC to find out what can be unlocked when founders leverage a SOTA reasoning model.

Earlier this month, OpenAI raised the largest venture round ever at $6.6 billion. The company’s CFO says AI is now at the point where orders of magnitude matter and the next generation of models will be capital intensive. In this episode of the Lightcone, the hosts consider what a world with ultra-intelligent models would look like, and what potential unlocks could be made possible.

With rapid advancements in LLMs, AI can now follow prompts to generate code and build functional custom software. So, how does the tech landscape change when coding becomes accessible to everyone? In this episode of Lightcone, we sat down with Amjad Masad, CEO of Replit—an AI-powered platform for software development and deployment—to explore how anyone can now tap into the power of coding.

As LLMs continue to improve, it's clear that vertical AI agents are key to the next generation of billion-dollar SaaS opportunities. In this episode of the Lightcone, we sat down with Jake Heller, the co-founder and CEO of Castext— which sold to Thomson Reuters for $650 million in 2023— to discuss what it takes to build a successful vertical AI company.

Suhail Doshi, a YC alumni who previously founded Mixpanel and Mighty, has created a state-of-the-art (SOTA) AI image diffusion model with Playground. The app allows you to talk to it like a graphic designer and helps you create imagery and text for a wide variety of use cases. In this episode of Lightcone, Suhail sits down with the hosts to talk about his experience building Playground with his team and what it takes to make a SOTA model. Try Playground:...

It’s the first guest episode of Lightcone! The hosts sit down with Paul Buchheit, one of Google’s earliest employees, the creator of Gmail and current YC Group Partner. (He also came up with Google’s famous tagline “Don’t be evil.”) This discussion covers a wide range of topics including the future of AGI, the early days of OpenAI and the crucial importance of open source models.

As AI continues to evolve and advance, a line of thinking has emerged that humans will no longer need to learn how to write code in the future. If so, could this mean that a staff of ten or less could create a unicorn? The hosts of Lightcone analyze this prediction and discuss whether it has merit.

There's been a lot of news lately about the updates to some of the largest foundational AI models. But what does this mean for startups? How will future product releases from the AI giants effect the companies built on top of them? The hosts of Lightcone discuss how founders can take advantage of these developments and avoid being steamrolled by the competition.

Last month, YC hosted Startup School East, a one-day event in Boston for university students. As part of the event, the Lightcone Podcast did their first live stage recording specifically tailored for the students.

YC has become a surprising force in the hard tech world, funding startups building physical products from satellites to rockets to electric planes. In this episode of Lightcone, we go behind the scenes to explore how YC advises founders on their ambitious startups. We also take a look at a number of YC's hard tech companies and how they got started with little time or money.

If you read articles about companies like OpenAI and Anthropic training foundation models, it would be natural to assume that if you don’t have a billion dollars or the resources of a large company, you can’t train your own foundational models. But the opposite is true. In this episode of the Lightcone Podcast, we discuss the strategies to build a foundational model from scratch in less than 3 months with examples of YC companies doing just that. We also get an exclusive look at Open AI's...
