https://huggingface.co/IDEA-Research/grounding-dino-tiny with ONNX weights to be compatible with Transformers.js.

Usage (Transformers.js)

If you haven't already, you can install the Transformers.js JavaScript library from NPM using:

npm i @huggingface/transformers

Example: Zero-shot object detection with onnx-community/grounding-dino-tiny-ONNX.

import { AutoModelForZeroShotObjectDetection, AutoProcessor, load_image } from "@huggingface/transformers";

// Load model and processor
const model_id = "onnx-community/grounding-dino-tiny-ONNX";
const processor = await AutoProcessor.from_pretrained(model_id);
const model = await AutoModelForZeroShotObjectDetection.from_pretrained(model_id, { dtype: "fp32" });

// Prepare image and text inputs
const image = await load_image("http://images.cocodataset.org/val2017/000000039769.jpg");
const text = "a cat."; // NB: text query needs to be lowercased + end with a dot

// Preprocess image and text
const inputs = await processor(image, text);

// Run model
const outputs = await model(inputs);

// Post-process outputs
const results = processor.post_process_grounded_object_detection(
  outputs,
  inputs.input_ids,
  {
    box_threshold: 0.3,
    text_threshold: 0.3,
    target_sizes: [image.size.reverse()],
  },
);
console.log(results);
