Comparing OpenAI and Anthropic’s Data Retention Policies: How OpenAI’s Private Safety Processing and Anthropic's Enterprise Frontier Safeguards affect ZDR policies
Anyone who sends private data to an AI model or service deserves a clear answer to three questions: (i) Where do they store it? (ii) How long do they keep it? and (iii) What, if anything, will they do with it (such as train on it, show to humans, etc.)

Better Reward Models for Robots: Inside RoboReward, a family of vision-language reward models that train robots to take action
When you’re training a robot via reinforcement learning, a handcrafted reward function is labor-intensive to build but often dispenses rewards more effectively than a general-purpose reward model based on a vision-language model. Researchers built reward models that narrowed the gap.
