ONNX neural network inference engine

An 8M-parameter English text-to-speech model distilled from Kokoro-82M. 9 MB, runs 18x real time on one CPU thread.

Multilingual neural TTS (6 languages: JA/EN/ZH/ES/FR/PT, code supports SV) — C++, C#, Rust, Go, Python, npm (WASM). VITS + Prosody, streaming, CUDA/CoreML/DirectML. pip install piper-plus | npm install piper-plus | cargo install piper-plus-cli

Run open decision models locally: pull and serve Laya, decider, NLI and GLiClass behind a TypeSafe-compatible API. Ollama for decision models.

Local code search combining BM25, vector similarity, and cross-encoder reranking. Parses 60+ languages with tree-sitter, runs entirely offline, and returns structured results with file paths, line ranges, and symbol metadata. Built in Rust.

Peak compute, memory bandwidth and latency of CPUs, GPUs and NPUs: the same tests through every API that reaches a device. Command line and app for Windows, macOS, Linux and Android

An open-source project for Windows developers to learn how to add AI with local models and APIs to Windows apps.

Ultralytics YOLOv5 in PyTorch for object detection, instance segmentation, classification, training, and export.

Fast and accurate AI powered file content types detection

An OBS plugin for removing background in portrait images (video), making it easy to replace the background when recording or streaming.

Open-source, offline voice-to-text for macOS. Hold a hotkey, speak, text appears. Private on-device dictation with multiple speech engines.

ONNX Optimizer

AI-powered desktop app for stunning image transformations

Learn to sing the songs you love. A free, open-source singing trainer for Mac that listens to the music you play.

MuJoco Simulation on WebAssembly with Neural networks

GUI for upscaling and interpolating videos with ONNX models on Windows and Linux, using TensorRT, TensorRT-RTX or DirectML

Long-term memory for any AI agent. One Rust binary, offline, 98.2% recall@5 on LongMemEval-S. Self-host free or use Uteke Cloud.

Knowledge Management for Humans and Agents

AMD MIVisionX is a computer vision toolkit built around a highly optimized, conformant open-source implementation of the Khronos OpenVX™ 1.3.2 specification. As of the 4.0.0 release, MIVisionX ships three components: the AMD OpenVX™ engine, the AMD RPP OpenVX extension, and the RunVX graph executor — across CPU, HIP, and OpenCL backends.

ONNX Runtime Server: The ONNX Runtime Server is a server that provides TCP and HTTP/HTTPS REST APIs for ONNX inference.
