A new way to “paint with light” to create radiant, color-changing items

A new way to “paint with light” to create radiant, color-changing items

A new study reveals that the color variability in gemstones like opal is due to their internal structure, which diffracts light differently based on the viewing angle. This insight not only enhances our understanding of gemstone aesthetics but also may improve synthetic gemstone creation, enabling more precise color manipulation in the jewelry industry.

Jet-RL: Enabling On-Policy FP8 Reinforcement Learning with Unified Training and Rollout Precision Flow

Jet-RL: Enabling On-Policy FP8 Reinforcement Learning with Unified Training and Rollout Precision Flow

Research highlights the inefficiencies of current reinforcement learning (RL) pipelines for large language models, where rollout phases consume over 70% of training time. A study reveals that the common BF16 + FP8 strategy leads to instability and accuracy loss. Introducing Jet-RL, which uses unified FP8 precision for training and rollout, improves efficiency by up to 41% and stabilizes convergence with minimal accuracy impact.
