RekaAILabs · x · 2026-07-22
Reka AI shared insights into building the data platform behind their 'Physical AI' and world model training.
- Team & Challenge: Led by Konrad Jam, a team of fewer than 100 people prepares hundreds of thousands of hours of video data for world model training, dealing with petabyte-scale data.
- Data Dictates Capability: Researchers Julian López and Fedor Zhdanov emphasize that before a single model weight is updated, it's crucial to understand the data's composition. Composition, quality, and annotation directly determine what the world model actually learns.
- Engineering Pace: To keep pace with a fast-moving research team, the data pipeline requires highly dynamic day-to-day operations.
