# Generative AI with ONNX Runtime

_Note: this API is in preview and is subject to change._

Run generative AI models with ONNX Runtime. Source code: https://github.com/microsoft/onnxruntime-genai 

This library provides the generative AI loop for ONNX models, including inference with ONNX Runtime, logits processing, search and sampling, and KV cache management.

Users can call a high level `generate()` method, or run each iteration of the model in a loop, generating one token at a time, and optionally updating generation parameters inside the loop.

It has support for greedy/beam search and TopP, TopK sampling to generate token sequences and built-in logits processing like repetition penalties. You can also easily add custom scoring.
