  "description" : "This `onnx-genai` resource loads and initializes an ONNX GenAI model that processors can reference.\nIt handles downloading and caching of model files, as well as loading the necessary native libraries.\n\nSee the official ONNX GenAI [github repo](https://github.com/microsoft/onnxruntime-genai) for more information.\n\n## Models\n\nSupported model architectures as of onnx-genai-0.8.3 release are: AMD OLMo, ChatGLM, DeepSeek, ERNIE 4.5,\nGemma, Granite, Llama (and derivatives), Mistral (and derivatives), Nemotron, Phi (language + vision), Qwen\n\n## Downloads\n\nThe `modelUri` can point to a location on local disk (using `file://` scheme) or on a remote storage.\nRemote storage support depends on available plugins, e.g., S3 plugin allows downloads from an S3-compatible bucket.\n\n## Files\n\nThe `modelUri` should point to a location containing the following files:\n— genai_config.json\n— model.onnx\n— model.onnx.data\n— tokenizer.json\n— tokenizer_config.json\n",
