Official PyTorch Implementation of the Recognize Anything Model (RAM) and the Tag2Text Model.

• RAM is a strong image tagging model, which can recognize any common category with high accuracy.
• Tag2Text is an efficient and controllable vision-language model with tagging guidance.

When combined with localization models (Grounded-SAM), Tag2Text and RAM form a strong and general pipeline for visual semantic analysis.

Recognition and localization are two foundation computer vision tasks.

• The Segment Anything Model (SAM) excels in localization capabilities, while it falls short when it comes to recognition tasks.
• The Recognize Anything Model (RAM) and Tag2Text exhibits exceptional recognition abilities, in terms of both accuracy and scope.

Tag2Text for Vision-Language Tasks.

• Tagging. Without manual annotations, Tag2Text achieves superior image tag recognition ability of 3,429 commonly human-used categories.
• Efficient. Tagging guidance effectively enhances the performance of vision-language models on both generation-based and alignment-based tasks.
• Controllable. Tag2Text permits users to input desired tags, providing the flexibility in composing corresponding texts based on the input tags.

Advancements of RAM on Tag2Text.

• Accuracy. RAM utilizes a data engine to generate additional annotations and clean incorrect ones, resulting higher accuracy compared to Tag2Text.
• Scope. Tag2Text recognizes 3,400+ fixed tags. RAM upgrades the number to 6,400+, covering more valuable categories. With open-set capability, RAM is feasible to recognize any common category.

• Tag2Text/RAM with Grounded-SAM is trong and general pipeline for visual semantic analysis, which can automatically recognize, detect, and segment for an image!
• Ask-Anything is a multifunctional video question answering tool. Tag2Text provides powerful tagging and captioning capabilities as a fundamental component.
• Prompt-can-anything is a gradio web library that integrates SOTA multimodal large models, including Tag2text as the core model for graphic understanding
