LoongForge is Baidu's production-proven training framework derived from AIAK-Training-LLM, supporting LLMs, VLMs, diffusion, and embodied VLA models with multi-backend architecture (Megatron and torch-native). It delivers substantial throughput gains (up to 4.38× on DreamZero, 3× on Pi0.5) while keeping loss curves aligned, and ships ready-to-run recipes for 40+ models plus checkpoint conversion and data preprocessing tools.
Target audience: ML engineers and researchers training large language, vision-language, diffusion, and embodied/VLA models at scale
