hanzo-ml 0.11.39

Fast multi-backend tensor & ML framework for Rust (CPU/CUDA/Metal/Vulkan/ROCm) with quantization — the compute core of the Hanzo stack.
Documentation

Hanzo ML

A fast, multi-backend tensor and machine-learning framework for Rust — the compute substrate behind Hanzo inference.

Backends

One tensor API across CPU (SIMD / MKL / Accelerate), CUDA — including unified/managed memory for NVIDIA GB10 / DGX Spark — Metal (Apple Silicon), Vulkan, and ROCm (AMD RDNA3.5 APUs).

Features

  • Quantization — the full GGUF/GGML zoo (Q/K, legacy, IQ1–4, TQ) plus GPTQ / AWQ / AFQ / MXFP4, much of it bit-exact and GPU-resident.
  • Multimodal — text, vision, audio, and 3D.
  • WebAssembly — run models in the browser.
  • Rust-native — memory-safe, zero-cost abstractions; pairs with Hanzo Engine for serving.

Quick start

use hanzo_ml::{Device, Tensor};

let device = Device::Cpu; // or Device::new_cuda(0)?, Device::new_metal(0)?
let a = Tensor::randn(0f32, 1., (2, 3), &device)?;
let b = Tensor::randn(0f32, 1., (3, 4), &device)?;
println!("{}", a.matmul(&b)?); // Tensor[[2, 4], f32]

See the repository for examples, the guide book, and the model zoo.
