We introduce ZServe, an adaptive framework designed to optimize the deployment of large language models (LLMs) in production environments. ZServe tackles critical challenges in LLMs serving with three key innovations: (1) Resource-aware Parameter Mining, which automatically identifies optimal hardware configurations for various accelerators, eliminating the need for manual tuning while maximizing performance; (2) Task-aware Dynamic Reconfiguration, which seamlessly switches between SLO-centric and throughput-centric serving modes based on real-time workload characteristics without service disruption; and (3) A Unified Monitoring and Scaling Interface, which simplifies deployment management across heterogeneous infrastructures. In contrast to static frameworks like RayServe and Xinference, ZServe introduces dynamic runtime adaptation, leveraging novel queue handoff and memory-efficient state migration to switch serving modes without dropping in-flight requests. Experimental results with LLMs from 7B to 70B parameters show that ZServe achieves up to 45% higher throughput during peak periods while preserving latency targets during moderate traffic, demonstrating scalability across single-node and multi-node deployments.
Code sandboxes have emerged as a critical infrastructure for advancing the coding capabilities of large language models, providing verifiable feedback for both RL training and evaluation. However, existing systems fail to provide accurate verification and efficiency under high-concurrency workloads. We present ScaleBox, a high-fidelity and scalable system designed to address these limitations in large-scale code training. ScaleBox introduces automated special-judge generation and management, fine-grained parallel execution across test cases with seamless multi-node coordination, and a configuration-driven evaluation suite for reproducible benchmarking. A series of experiments demonstrates that ScaleBox significantly enhances code verification accuracy and efficiency. Our further RLVR experiments show that ScaleBox substantially improves both performance on LiveCodeBench and training stability, significantly outperforming heuristic-matching baselines. By providing a reliable and high-throughput infrastructure, ScaleBox facilitates more effective research and development in large-scale code training.
