LoongForge is an open‑source, Megatron‑based multimodal training framework that unifies LLM, VLM, VLA and diffusion models, runs seamlessly on NVIDIA GPUs and Baidu Kunlun XPU, and delivers 15%‑45% end‑to‑end training acceleration while scaling linearly on thousands of cards.
The open‑source GLM‑5.1 model, adapted to Baidu Baige's Kunlun XPU via the vLLM‑Kunlun Plugin, delivers record‑breaking SWE‑bench scores, eight‑hour autonomous coding, long‑context handling up to 64K tokens, and scalable deployment across tens of thousands of chips, showcasing end‑to‑end AI acceleration.
This article details the technical challenges of adapting the open‑source vLLM inference framework to Baidu's Kunlun XPU, outlines four major performance bottlenecks, and presents a multi‑dimensional optimization roadmap—including custom plugins, operator fusion, INT8 quantization, and CUDA‑Graph techniques—that together boost throughput by up to 8% and narrow the gap with leading GPU hardware.
Baidu Baige built a full‑stack quantization pipeline that integrates model‑level, framework‑level, and hardware‑level optimizations on the Kunlun XPU platform, enabling FP16/BF16 large models to be compressed to 25‑50% of their original size while boosting inference speed by 30‑50% and dramatically reducing memory consumption for enterprise deployments.
This article explains how Baidu's new GLM-5 large model is adapted to the Kunlun P800 XPU, detailing the async reinforcement learning framework Slime, optimization techniques like INT8 quantization and tensor‑parallelism, and provides step‑by‑step deployment commands using the open‑source vLLM‑Kunlun plugin.
Within two days, Baidu’s Baige and Kunlun Chip teams adapted the 309‑billion‑parameter MiMo Flash V2 model—featuring a hybrid SWA+Sink and Full Attention mechanism—to run efficiently on the Kunlun P800 XPU using the vLLM‑Kunlun Plugin, achieving lossless performance comparable to GPU inference.
The vLLM‑Kunlun Plugin, jointly released by Baidu Baige and Kunlun Chip, provides a high‑performance, zero‑intrusion solution for deploying open‑source large language models on domestic Kunlun XPU hardware, includes fused operators, precision‑validation and profiling tools, and supports over twenty mainstream and multimodal models.
