Local Inference of LLMs on Long Contexts: A Data Systems Perspective

In this paper, we set out to study the limitations that prevent serving long-context models for single users, besides the capacity issue.

Key points

  • Large language models can solve complex problems across a variety of subjects, such as mathematics and coding.
  • The common understanding, however, is that local LLMs need compression (e.g., quantization) to run on a single GPU.
  • Rather than characterizing a single model on one GPU, we analyze how different models behave across several GPU generations.
  • Our analysis confirms that, as expected, self-attention dominates the runtime for long-context inference.
