Summary

FlashInfer-Bench provides a benchmark suite and production workflow aimed at creating self-improving AI systems, specifically for Large Language Models (LLMs). It targets AI agents and engineers by enabling collaborative optimization of the underlying kernels that power LLMs, fostering a virtuous cycle where AI improves AI. The primary benefit is enhanced performance and efficiency of LLM systems through continuous kernel optimization.

How It Works

The project establishes a feedback loop for LLM kernel optimization. It utilizes the "FlashInfer-Trace" dataset, which comprises kernels and workloads derived from real-world AI system deployments. This dataset allows FlashInfer-Bench to measure and compare the performance of various kernels. The core approach facilitates a collaborative environment where AI agents and engineers can work together to refine these critical components, leading to a self-improving ecosystem for AI infrastructure.

Quick Start & Requirements

• Installation: Install via pip: pip install flashinfer-bench.
• Prerequisites: Python environment. Git LFS is required for cloning the dataset.
• Dataset: The official "FlashInfer-Trace" dataset is available on HuggingFace (https://huggingface.co/datasets/flashinfer-ai/flashinfer-trace). Clone it using GIT_LFS_SKIP_SMUDGE=1 git clone https://huggingface.co/datasets/flashinfer-ai/flashinfer-trace.
• Running Benchmarks: Execute benchmarks using flashinfer-bench run --local flashinfer-trace.
