DynSTEER: Dynamic Stage-wise Trajectory Evaluation and Execution-time Review for Agents

Large language model agents are increasingly deployed for long-horizon task execution, raising a central granularity question for trajectory evaluation: whole-trajectory verification is too coarse to capture concrete failures and their associated evidence in long trajectories, while atomic-step scoring is too fine-grai...

Envs-FORGE: Frontier-Optimized Reward-Grounded Environment Synthesis for Agent RL

Envs-FORGE is presented, a prompting policy that converts verifier rewards into per-seed environment-synthesis actions and solves a per-seed mixed-integer linear program (MILP) to choose the action that conditions generation.

DataFoundry: Evolving Data Preparators via Recursive Self-Improvement

The DataFoundry is introduced, a framework for evolving data preparators through recursive self-improvement before large-scale data production, and it is found that recursively evolved preparators produce training data with higher downstream utility than baselines.

LazyTrain: Limited-resource Allocation toward Zero-waste Yield Optimization in Large Language Model Training

LazyTrain is proposed, an optimization layer over a layer-streaming executor that formulates checkpoint selection, activation placement, recomputation, and CPU-GPU-NVMe communication overlap as a mixed-integer scheduling problem, then executes the solved policy during training.
