🔥 [2025/10/15] Rex-Omni: Still using traditional detectors? We've turned object detection into a simple "Next-Token Prediction" task with an MLLM! One model (fully open-sourced), zero-shot SOTA performance, tackling detection, referring, OCR, and GUI grounding all at once. Come see the next generation of perception models
2024-06-24: We have introduced two new free products based on T-Rex2:
Count Anything APP: CountAnything is a versatile, efficient, and cost-effective counting tool that utilizes advanced computer vision algorithms, specifically T-Rex, for automated counting. It is applicable across various industries, including manufacturing, agriculture, and aquaculture.
T-Rex Label: T-Rex Label is an advanced annotation tool powerd by T-Rex2, specifically designed to handle the complexities of various industries and scenarios. It is the ideal choice for those aiming to streamline their workflows and effortlessly create high-quality datasets.
2024-05-17: Grounding DINO 1.5 is released. This is IDEA Research's Most Capable Open-World Object Detection Model Series. It can detect any object throught text prompts!
Object detection, the ability to locate and identify objects within an image, is a cornerstone of computer vision, pivotal to applications ranging from autonomous driving to content moderation. A notable limitation of traditional object detection models is their closed-set nature. These models are trained on a predetermined set of categories, confining their ability to recognize only those specific categories. The training process itself is arduous, demanding expert knowledge, extensive datasets, and intricate model tuning to achieve desirable accuracy. Moreover, the introduction of a novel object category, exacerbates these challenges, necessitating the entire process to be repeated.
T-Rex2 addresses these limitations by integrating both text and visual prompts in one model, thereby harnessing the strengths of both modalities. The synergy of text and visual prompts equips T-Rex2 with robust zero-shot capabilities, making it a versatile tool in the ever-changing landscape of object detection.
What Can T-Rex Do 📝
T-Rex2 is well-suited for a variety of real-world applications, including but not limited to: agriculture, industry, livstock and wild animals monitoring, biology, medicine, OCR, retail, electronics, transportation, logistics, and more. T-Rex2 mainly supports three major workflows including interactive visual prompt workflow, generic visual prompt workflow and text prompt workflow. It can cover most of the application scenarios that require object detection
In interactive visual prompt workflow, users can provide visual prompts in boxes or points format on a given image to specify the object to be detected.
You are supposed get the following visualization results at demo_vis/

Generic Visual Prompt API
In generic visual prompt workflow, users can provide visual prompts on one reference image
and detect on the other image.

Customize Visual Prompt Embedding API
In this workflow, you can customize a visual embedding for a object category using multiple images. With this embedding, you can detect on any images.
Draw Box: Draw a box on the image to specify the object to be detected. Drag the left mouse button to draw a box.
Draw Point: Draw a point on the image to specify the object to be detected. Click the left mouse button to draw a point.
Interactive Visual Prompt: Provide visual prompts in boxes or points format on a given image to specify the object to be detected. The Input Target Image and Interactive Visual Prompt Image should be the same
Generic Visual Prompt: Provide visual prompts on multiple reference images and detect on the other image.
5. Related Works
:fire: We release the training and inference code and demo link of DINOv, which can handle in-context visual prompts for open-set and referring detection & segmentation. Check it out!
