AI Models Can Provably Hide Arbitrary Capabilities

Ecology of AI Agents: Collaboration Creates a Population Threshold for Takeoff

Specialists Learn Faster: Knowledge Organization in Pre-training Shapes Knowledge Update Efficiency

Returning to Development States: When Full Sandbox Snapshots Help Coding Agents

DualQuant: Dual-scale Calibration-free Weight-and-Activation Quantization for LLMs
