ChatGPT is a product from OpenAI which acts like a chatbot based on GPT technology. GPT stands for Generative Pre-trained Transformer. It is a type of Large Language Model, or LLM. Many companies, including Instabase leverage GPT models as part of their products. GPT models are pre-trained on billions of input data, and are used to help understand language in a similar way humans would. OCR stands for Optical Character Recognition. It is a technology that is used to make documents machine readable. Examples are handwritten documents. Advanced AI companies like Instabase use OCR as the first step in a digitization process that is then followed by other complex technologies based on Deep Learning to classify documents and extract specific fields from those documents. OCR ChatGPT together refers to the idea of making documents machine readable and leveraging GPT models to understand these documents in a similar way a human would. Instabase is a company that leverages OCR and GPT technologies as part of its platform.
