Residual Visual Credit Optimization: Conserved Evidence Routing for Multimodal Reinforcement Learning

Reinforcement learning with verifiable rewards scales multimodal reasoning, but an outcome reward says how much a trajectory is worth, not how that value should be spread over the decisions that produced it. We introduce Residual Visual Credit Optimization (RVCO), which treats token credit as a conserved routing proble...

Self-Evolving Memory for Generative Recommendation

A self-evolving memory paradigm for generative recommendation is proposed, aiming to enable effective evolution across heterogeneous behavioral patterns, and three key principles for effective self-evolving recommendation systems are identified, including isolated memorization, reinforced evolution, and scalable applic...

Text Has Curvature

This work argues that text does indeed have curvature, and shows how to detect it, define it, and use it, and establishes a text-native curvature paradigm, making Texture practically useful.

Knowledge Distillation During Mid-Training Favors Reasoning over Factual Recall

Switch Distillation is proposed, a simple mid-training objective that distills on tokens where the teacher is confident, using teacher predictive entropy as a lightweight routing signal, and otherwise falls back to cross-entropy, which consistently outperforms existing distillation objectives across teacher sizes.

EvoHarness-RL: Learning Self-Evolving Runtime Harness for Long-Horizon LLM Agents

EvoHarness-RL is introduced, which exposes Belief, Progress, and Experience (BPE) as policy-facing harness state and reveals two key dynamics: harness annealing, where training internalizes recurring harness-use patterns into the model policy and shifts the agent from frequent harness calls toward selective external-st...
