TMS: Trajectory-Mixed Supervision for Reward-Free, On-Policy SFT

Rana Muhammad Shahroz Khan, Zijie Liu, Zhen Tan +2

Reinforcement Learning (RL) and Supervised Fine-Tuning (SFT) are the two dominant paradigms for enhancing Large Language Model (LLM) performance on downstream tasks. While RL gener…

Scaling Agentic Reinforcement Learning for Tool-Integrated Reasoning in VLMs

Meng Lu, Ran Xu, Yi Fang +14

While recent vision-language models (VLMs) demonstrate strong image understanding, their ability to "think with images", i.e., to reason through multi-step visual interactions, rem…

Command-V: Pasting LLM Behaviors via Activation Profiles

Barry Wang, Avi Schwarzschild, Alexander Robey +4

Retrofitting large language models (LLMs) with new behaviors typically requires full finetuning or distillation-costly steps that must be repeated for every architecture. In this w…
