In this podcast, we dive into the new concept of OCR 2.0 - the future of OCR with LLMs.
We explore how this new approach addresses the limitations of traditional OCR by introducing a unified, versatile system capable of understanding various visual languages. We discuss the innovative GOT (General OCR Theory) model, which utilizes a smaller, more efficient language model. The podcast highlights GOT's impressive performance across multiple benchmarks, its ability to handle real-world challenges, and its capacity to preserve complex document structures. We also examine the potential implications of OCR 2.0 for future human-computer interactions and visual information processing across diverse fields.

All right, so we're diving into the future of OCR today. Really interesting stuff.
Yeah, and you know how sometimes you just gain a document, you just want the text, you don't really think twice about it. Right, right. But this paper, General OCR Theory, towards OCR 2.0 via a unified end-to-end model. Catchy title. I know, right? But it's not just the title, they're proposing this whole new way of thinking about OCR. OCR 2.0 as they call it. Exactly, it's not just about text anymore. Yeah, it's really about understanding any kind of visual information, like humans do. So much bigger. It's a really ambitious goal. Okay, so before we get ahead of ourselves, let's back up for a second. Okay. How does traditional OCR even work? Like when you and I scan a document, what's actually going on? Well, it's kind of like, imagine an assembly line, right? First, the system has to figure out where on the page the actual text is. Find it. Right, isolate it. Then it crops those bits out. Okay. And then it tries to recognize the individual letters and words. So it's like a multi-step? Yeah, it's a whole process. And we've all been there, right? When one of those steps goes wrong. Oh, tell me about it. And you get that OCR output that's just… Gibberish, told gibberish. The worst. And the paper really digs into this. They're saying that whole assembly line approach, it's not just prone to errors, it's just clunky. Yeah, very inefficient. Like different fonts can throw it off. And write. Different languages, forget it. Oh yeah, if it's not basic printed text, OCR 1.0 really struggles. It's like it doesn't understand the context. Yeah, exactly. It's treating information like it's just a bunch of isolated letters, instead of seeing the bigger picture, you know, the relationships between them. It doesn't get the human element of it. It's missing that human touch, that understanding of how we visually organize information. And that's a problem. A big one. Especially now, when we're just like drowning in visual information everywhere you look. It's true, we need something
