Tract is Sonos' tiny, self-contained neural-network inference engine written in Rust. It loads ONNX, TensorFlow/TFLite, and NNEF models, optimizes them, and runs them on everything from embedded ARM CPUs to GPUs and WebAssembly.

Use cases

• run onnx models in rust
• neural network inference on embedded arm devices
• run llm inference locally in rust
• speech recognition inference for wake word detection
• run stable diffusion models without python
• run machine learning models in the browser via webassembly
• deploy tensorflow lite models on edge devices

When to choose

• you need a small, self-contained inference runtime with no heavy dependencies
• you target embedded or resource-constrained hardware
• you want to ship a tiny runtime with models pre-translated to NNEF
• you need ONNX or TFLite inference in Rust or Python across many platforms

When to avoid

• you need the full training or ecosystem tooling of PyTorch or TensorFlow
• you require broad operator coverage for exotic models
• you depend on internal tract crates, which are not a stable API
