State commitment learning: training language models to distinguish computation from memory

arXiv:2606. 05201v1 Announce Type: new Abstract: Reasoning language models do not distinguish tokens used for computation from tokens that constitute persistent state: once generated, all hidden thoughts remain in context and influence future predictions.

Right Makes Might: Aligning Verified Hidden States Empowers RL Reasoning

arXiv:2606. 03234v1 Announce Type: new Abstract: Reinforcement Learning from Verifiable Rewards (RLVR) has become the dominant approach for improving mathematical reasoning in large language models, yet current methods reduce each correct rollout to a single reward bit, ignoring the geometric structure shared among their hidden states.

Continual Reasoning Gym: Diagnosing and Harnessing Shared Reasoning in Continual RLVR

The paper introduces Continual Reasoning Gym, a continual reinforcement learning with verifiable rewards (RLVR) environment that sequences text and visual reasoning tasks. It finds that sequential RLVR suffers modest forgetting and underperforms multitask RLVR, but that shared reasoning structures can be leveraged. The authors propose Continual Prompt Replay (CPR), which replays previous-task prompts and regenerates responses, achieving performance comparable to multitask RLVR.

Hidden Forgetting in Continual Multimodal Learning: When Accuracy Survives but Grounding Fails

arXiv:2607. 02020v1 Announce Type: new Abstract: Multimodal large language models must continually adapt to evolving tasks and domains, yet standard continual learning metrics mainly measure whether old answers remain correct, leaving the stability of multimodal grounding largely unexamined.
