CoBind: Stage-Aware Compositional Binding for Training-Free Text-to-Image Generation

CoBind is introduced, a training-free framework for stage-aware compositional binding that parses a prompt into a composition graph of entities, attributes, and relations and adapts the guidance strength according to the current satisfaction of each constraint, reducing unnecessary latent updates.

LongStraw: Long-Context RL Beyond 2M Tokens under a Fixed GPU Budget

This work presents LongStraw, an objective-aware, architecture-aware system for resident-state virtualization, response replay, and distributed-gradient execution that bounds the live training graph by the response suffix while reusing the expensive prompt computation across the complete GRPO group.
