+# LLMDet (tiny variant)
+[LLMDet](https://arxiv.org/abs/2501.18954) model was proposed in [LLMDet: Learning Strong Open-Vocabulary Object Detectors under the Supervision of Large Language Models
+](https://arxiv.org/abs/2501.18954) by Shenghao Fu, Qize Yang, Qijie Mo, Junkai Yan, Xihan Wei, Jingke Meng, Xiaohua Xie, Wei-Shi Zheng.
+LLMDet improves upon the [MM Grounding DINO](https://huggingface.co/docs/transformers/model_doc/mm-grounding-dino) and [Grounding DINO](https://huggingface.co/docs/transformers/model_doc/grounding-dino) by co-training the model with a large language model by generating detailed image-level captions.
+You can find all the LLMDet checkpoints under the [LLMDet](https://huggingface.co/collections/rziga/llmdet-68398b294d9866c16046dcdd) collection. Note that these checkpoints are inference only -- they do not include LLM which was used for training. The inference is identical to that of [MM Grounding DINO](https://huggingface.co/docs/transformers/model_doc/mm-grounding-dino).
+## Intended uses
+You can use the raw model for zero-shot object detection.
+Here's how to use the model for zero-shot object detection:
+```py
+import torch
+from transformers import AutoModelForZeroShotObjectDetection, AutoProcessor
+from transformers.image_utils import load_image
+# Prepare processor and model
+model_id = "rziga/llmdet_tiny"
+device = "cuda" if torch.cuda.is_available() else "cpu"
+processor = AutoProcessor.from_pretrained(model_id)
+model = AutoModelForZeroShotObjectDetection.from_pretrained(model_id).to(device)
+# Prepare inputs
+image_url = "http://images.cocodataset.org/val2017/000000039769.jpg"
+image = load_image(image_url)
+text_labels = [["a cat", "a remote control"]]
+inputs = processor(images=image, text=text_labels, return_tensors="pt").to(device)
+# Run inference
+with torch.no_grad():
+    outputs = model(**inputs)
+# Postprocess outputs
+results = processor.post_process_grounded_object_detection(
+    outputs,
+    threshold=0.4,
+    target_sizes=[(image.height, image.width)]
+)
+# Retrieve the first image result
+result = results[0]
+for box, score, labels in zip(result["boxes"], result["scores"], result["labels"]):
+    box = [round(x, 2) for x in box.tolist()]
+    print(f"Detected {labels} with confidence {round(score.item(), 3)} at location {box}")
+```
+## Training Data
+This model was trained on:
+ - [GroundingCap-1M](https://arxiv.org/abs/2501.18954)
+## Evaluation results
