Imagine watching a person ride a skateboard past your field of view. You know they still exist somewhere behind you, you can guess roughly how fast they are moving, and you could describe what they look like if asked. This is visu... ai Sep 18 An Empirical Study of Harness Design for Coding Agents Why the Wrapper Around the Model Matters More Than You Think When we talk about autonomous coding agents, the conversation usually centers on the model itself: which foundation model, how many parameters, what training data. But t... ai Sep 18 RetireOPD: Self-Retiring On-Policy Distillation for Agentic Reinforcement Learning When Your Teacher Becomes the Constraint Training language model agents on multi-turn tasks with reinforcement learning has a fundamental sparse-reward problem. An agent interacts with an environment over many steps, but receives... ai Sep 18 RAFT: A Stateful Retrieval-Augmented Framework for Troubleshooting Agents Why Troubleshooting Agents Need Stateful Retrieval, Not Static Document Lookup Enterprise customer support tickets do not resolve in a single shot. They unfold across stages: a symptom report, hypothesis formation, iterative log i... ai Sep 18 Should This Case Be Adapted? Prediction Fragmentation Controls Test-Time Adaptation The Hidden Problem With Test-Time Adaptation When a medical image segmentation model encounters a new scan from a different hospital or scanner, test-time adaptation (TTA) can help recover accuracy lost to distribution shift. The... ai Sep 17 PrismML hopes its tiny LLM will change how we all use AI A $22.25 million seed round does not normally move the needle in AI. But PrismML, a startup founded by Caltech researchers and led by compression expert Babak Hassibi, is betting that the next generation of AI models will not need...
