NVIDIA 如何为快速交互式长上下文推理协同设计 AI 模型注意力
Co-Designing AI Model Attention for Fast, Interactive Long-Context Inference
随着智能体与长上下文工作负载普及，注意力机制在推理耗时中占比越来越大，成为主导成本。NVIDIA 提出围绕 GPU 执行方式设计模型架构，即 AI 模型协同设计，以优化长上下文推理性能。
As agentic and long-context workloads become common, the context lengths increase and attention consumes a larger share of inference time (Figure 1). Because...
As agentic and long-context workloads become common, the context lengths increase and attention consumes a larger share of inference time (Figure 1). Because attention now dominates that cost, how it is designed—not just how it is implemented—increasingly determines a model’s inference performance. Shaping model architecture around how GPUs execute it is the premise of AI model co-design.
