Poetiq is a new startup founded by former DeepMind researchers that recently achieved a major jump on the ARC-AGI and Humanity's Last Exam benchmark by layering a recursive self-improvement system on top of existing models. In this episode of Lightcone, Poetiq's Founder & CEO Ian Fischer joined us to discuss how small teams can build “reasoning harnesses” that outperform base models, what that means for startups and why automating prompt engineering may be one of the most powerful levers in AI today.Chapters:00:00 – Intro00:40 – What Is Poetiq?01:07 – Recursive Self-Improvement Explained02:07 – The Fine-Tuning Trap02:59 – “Stilts” for LLMs03:14 – Recursive Self-Improvement vs. Fine-Tuning05:05 – Taking the Top Spot on ARC-AGI06:37 – Beating Claude on Humanity’s Last Exam08:40 – How the Meta-System Works10:26 – Beyond RL: A New S-Curve11:32 – Automating Prompt Engineering13:37 – From 5% to 95% Performance14:50 – Early Access & Putting Your Agent on Stilts16:17 – From YC Founder to DeepMind Researcher18:29 – Advice for Engineers in the AI EraApply to Y Combinator: https://www.ycombinator.com/applyWork at a startup: https://www.ycombinator.com/jobs


Behind every successful startup is a story, and the Y Combinator Startup Podcast is where those stories are told in full. This isn't about polished theory; it's the raw, practical conversation happening between founders who have been in the trenches and the Y Combinator partners who advise them. You'll hear directly from people who have navigated the chaotic journey from a flicker of an idea to building a company that scales, discussing not just their victories but, more importantly, the hard lessons and tactical decisions that aren't found in any textbook. Each episode feels like a candid office-hours session, stripping away the hype to focus on the real work of making something people actually want. For anyone curious about the mechanics of building a technology company-the early uncertainties, the pivotal moments, and the relentless focus on execution-this podcast offers an unfiltered look at the craft. Tune in for genuine insights from the frontlines, where the focus remains squarely on the art and science of building things that matter.
