About ONNX Runtime

ONNX Runtime is unbundling its execution providers into independently shippable plugins.

ONNX Runtime is mid-transition to a plugin-based execution-provider architecture: EPs that were once compiled into the core binary now ship as separately versioned libraries that register at runtime. Recent releases pair heavy LLM-oriented kernel work (attention, quantized MatMul/MoE, KV-cache) with deep security hardening across operators.
