Learn how to build and deploy custom CUDA kernels using the kernel-builder library, which streamlines the development process and ensures scalability and efficiency. The guide walks through creating a practical RGB to grayscale image conversion kernel with PyTorch, covering project structure, CUDA coding, and registration as a native PyTorch operator. It also discusses reproducibility, testing, and sharing the kernel with the community.

PyTorch has released native quantized models, including Phi4-mini-instruct and Qwen3, optimized for both server and mobile platforms using int4 and float8 quantization methods. These models offer efficient inference with minimal accuracy degradation and come with comprehensive recipes for users to apply quantization to their own models. Future updates will include new features and collaborations aimed at enhancing quantization techniques and performance.
