F2T: Fast Failover in LLM Training with Near-Zero Overhead State Management

Published in World Artificial Intelligence Conference Academic (WAICA), 2026

F2T leverages surplus network capacity to quickly save and load LLM training states, reducing recovery time by up to 98% and GPU utilization loss by up to 68%.

MLREF: Efficient Module Reuse for Reward Design in Reinforcement Learning via Large Language Models

Published in arXiv preprint, arXiv:2608.18827, 2026

MLREF evolves a persistent module pool for reward design in RL, reusing effective components across iterations and outperforming strong baselines by 25.2% in locomotion and 6.6% in manipulation.
