Technical Implementation

After seeing so many cool features, what exactly is InternGPT?

InternGPT (iGPT for short)/InternChat (iChat for short) is a visual interaction system driven by pointing language. Users can interact with ChatGPT by clicking, dragging and drawing.

Different from existing interaction systems that rely on pure language, by integrating pointing instructions, iGPT significantly improves the communication efficiency between users and chatbots, as well as the ability of chatbots to perform vision-centric tasks. accuracy, especially in complex visual scenes.

The following figure shows the overall architecture of InternGPT.

We can see that this GPT can process not only images and videos, but also voice and text.

For image or video input, InternGPT will use SAM (image segmentation model), OCR (image recognition model), etc. to process it.

After identifying a geographical location, object or line, there is a whole toolbox for further processing, all of which are familiar tools.

For example, BLIP (audio), Stable Diffusion (image), Pix2Pix (image translation), etc.

Similarly, for text or voice input, InternGPT will call GPT-4, LLaMA and other models or tools for processing, and there will also be a whole toolbox later.

Usage tips

The whole process is also very convenient during use.

After the user successfully uploads the image, he can send the following message to have a multi-modal related conversation with iGPT:

"what is it in the image?" or "what is the background color of image?".

Similarly, the user can also You can interactively operate, edit or generate pictures, as follows:

· Click anywhere on the picture, and then press the Pick button to preview the divided area. You can also press the OCR button to identify all words present at a specific location;

· To remove a masked area from an image, send the following message:

“remove the masked region”

· To replace the masked object with another object in the image, you can send the following message:

“replace the masked region with {your prompt}”

· If you want to generate a new image, you can send the following message:

“generate a new image based on its segmentation describing {your prompt}”

· To create a new image by doodling, press Whiteboard and draw on the whiteboard. After the drawing is completed, you need to press the save button and send the following message:

“generate a new image based on this scribble describing {your prompt}”
