OpenAI’s IMO Team on Why Models Are Finally Solving Elite-Level Math

Members of the OpenAI team, Alex Wei, Sheryl Hsu, and Noam Brown, discuss their model's historic gold-medal performance at the International Mathematical Olympiad (IMO). They detail their unique approach using general-purpose reinforcement learning for hard-to-verify tasks, the model's surprising self-awareness, and the vast gap that remains between solving competition problems and achieving true mathematical research breakthroughs.

Scaling and the Road to Human-Level AI | Anthropic Co-founder Jared Kaplan

Jared Kaplan, co-founder of Anthropic, explains how the discovery of predictable, physics-like scaling laws in AI training provides a clear roadmap for progress. He details the two main phases of model training (pre-training and RL), discusses how scaling compute predictably unlocks longer-horizon task capabilities, and outlines the remaining challenges—memory, nuanced oversight, and organizational knowledge—on the path to human-level AI.

[Full Workshop] Building Metrics that actually work — David Karam, Pi Labs (fmr Google Search)

This workshop, led by former Google product directors, introduces a methodology for building reliable and tunable evaluation metrics for LLM applications. It details how to create granular 'scoring systems' that break down complex evaluations into simple, objective signals, and then use these systems for model comparison, prompt optimization, and online reinforcement learning.
