EXPLANATION Checked Sep 23, 2026

GPT-4 System Developer Keynote & Real-Time Multimodal Demonstrations

Conducted the historic live technical demonstration of GPT-4, parsing a handwritten website mockup sketched on a napkin into functional HTML/JavaScript code in real time, and debugging complex tax calculations across a 16-page IRS document.

Model & Execution Context:GPT-4 multimodal vision checkpoint with 32k context window and zero-shot visual reasoning.

Scope & Limitations

Handwritten input legibility and complex nested mathematical tables require multiple-pass validation.

RESEARCH Checked Sep 23, 2026

Dota 2 with Large Scale Deep Reinforcement Learning (OpenAI Five)

Led the engineering and systems team that built OpenAI Five, scaling Proximal Policy Optimization (PPO) across 128,000 CPU cores and 256 GPUs playing 180 years of game simulation daily, defeating reigning world champion esports team OG.

Model & Execution Context:4,096-unit single-layer LSTM processing continuous state-action spaces with 20,000-step time horizons.

Scope & Limitations

Required heavy reward engineering and hero draft restrictions to converge on winning policies in complex game spaces.
