A new initiative called Ruitong has been launched to address the issue of accuracy drift in large language models (LLMs) when migrated across different hardware. While latency and cost are well-understood, the impact on model output has been largely unmeasured. Ruitong aims to provide a standardized, reproducible accuracy delta table to quantify these changes, enabling companies to better assess model performance when switching between hardware vendors or precisions. Initial findings indicate that even minor precision changes can lead to different outputs, though end-to-end functional equivalence gates often still pass. AI
