This repository offers a comprehensive course and framework for building custom Large Language Model (LLM) inference solutions. It targets engineers and researchers aiming to understand and implement high-performance LLM deployment, providing a project-oriented approach with detailed code analysis and interview preparation.

How It Works

The core of the framework is built using OpenAI Triton and PyTorch, enabling GPU kernel development with a Pythonic syntax that bypasses complex CUDA C++. This approach allows for efficient operator implementation, comparable to cuBLAS for matrix multiplication, and facilitates advanced features like FlashAttention, GQA, and PageAttention. It also includes sophisticated memory management and fused operators for optimized inference.

Quick Start & Requirements

• Install/Run: Not explicitly detailed, but implies a PyTorch and Triton environment.
• Prerequisites: Python, PyTorch, OpenAI Triton, CUDA (implied for GPU acceleration).
• Resources: Requires GPU hardware for effective operation.
• Links: No direct quick-start or demo links provided in the README.

Highlighted Details
