In plain English

Triton is a programming language and compiler for writing highly efficient custom operations for deep learning, particularly the kind that run on GPUs. When training or running AI models, much of the heavy computation happens in custom mathematical kernels (small, highly optimized programs that run on GPU hardware). Writing these in CUDA (NVIDIA's low-level GPU programming language) requires deep hardware expertise. Triton aims to offer a higher-level, more productive alternative while still producing fast code, described as offering higher productivity than CUDA but higher flexibility than other specialized languages. Triton uses MLIR (a compiler infrastructure framework) and LLVM internally to transform Python-like kernel code into GPU machine code. It is tightly integrated with the AI/ML ecosystem and is a key component powering PyTorch's compiled execution path (torch.compile). You would use Triton if you are a machine learning researcher or engineer who needs to write custom GPU kernels for performance-critical model components, but wants to work at a higher level of abstraction than raw CUDA. It installs via pip for CPython 3.10 through 3.14.
