Zhenan Fan contributed to the inclusionAI/AReaL repository by developing and enhancing advanced machine learning infrastructure over five months. He implemented LoRA-based disk-backed weight updates and robust vision-language model training on Ascend NPUs, focusing on scalable, distributed workflows and memory efficiency. Using Python and Ray, Zhenan integrated multi-node scheduling, improved reinforcement learning with on-policy knowledge distillation, and refactored backend servers for smoother live model updates. His work included technical documentation, API development, and memory management, resulting in more adaptable model deployments, faster ML iterations, and improved reliability. The depth of his contributions addressed both system scalability and developer usability.
March 2026 monthly summary for inclusionAI/AReaL focused on delivering high-impact features, stabilizing live inferences during model updates, and aligning documentation for production readiness. Key work spanned reinforcement learning improvements, server reliability enhancements for weight updates, and updated deployment documentation. Key outcomes include: - On-policy Knowledge Distillation in Reinforcement Learning: Enabled a student RL model to learn from a teacher while exploring its own policy, with configurable distillation loss weights and integration of teacher log probabilities into training. This improves sample efficiency and policy fidelity in dynamic environments. - Stability enhancement during weight updates: Refactored areal_vllm_server to replace abort_all_req with pause_generation, enabling smoother in-flight request handling and cache management during weight updates, reducing latency spikes and improving user experience. - NPU v1.0.1 documentation update: Updated documentation to reflect version 1.0.1, including changes to CANN version and AReaL images, supporting clearer deployment guidance for customers and internal teams.
