Steering LLMs via Scalable Interactive Oversight

Enyu Zhou, Zhiheng Xi, Long Ma +9

As Large Language Models increasingly automate complex, long-horizon tasks such as \emph{vibe coding}, a supervision gap has emerged. While models excel at execution, users often s…

CONCUR: High-Throughput Agentic Batch Inference of LLM via Congestion-Based Concurrency Control

Qiaoling Chen, Zhisheng Ye, Tian Tang +7

Batch inference for agentic workloads stresses the GPU key-value (KV) cache in a sustained and cumulative manner, often causing severe throughput degradation well before memory cap…

Nex-N1: Agentic Models Trained via a Unified Ecosystem for Large-Scale Environment Construction

AGI Team, Yuxuan Cai, Lu Chen +62

The evolution of Large Language Models (LLMs) from passive responders to autonomous agents necessitates a fundamental shift in learning paradigms -- from static imitation to incent…

ReSpec: Towards Optimizing Speculative Decoding in Reinforcement Learning Systems

Qiaoling Chen, Zijun Liu, Peng Sun +6

Adapting large language models (LLMs) via reinforcement learning (RL) is often bottlenecked by the generation stage, which can consume over 75\% of the training time. Speculative d…

BAPO: Stabilizing Off-Policy Reinforcement Learning for LLMs via Balanced Policy Optimization with Adaptive Clipping

Zhiheng Xi, Xin Guo, Yang Nan +18

Reinforcement learning (RL) has recently become the core paradigm for aligning and strengthening large language models (LLMs). Yet, applying RL in off-policy settings--where stale…

Expert-as-a-Service: Towards Efficient, Scalable, and Robust Large-scale MoE Serving

Ziming Liu, Boyu Tian, Guoteng Wang +15

Mixture-of-Experts (MoE) models challenge serving infrastructures with dynamic, sparse expert utilization, causing instability on conventional systems designed for dense architectu…
