NLP and Document AI are both part of a product suite offered by 1000ML that enables businesses to extract valuable insights from their documents using natural language processing (NLP) techniques. Unlike traditional document processing systems, Document AI employs semantics and context to understand the desired output, rather than being limited by pre-existing rules.

The suite includes entity extraction, summarization, sentiment analysis, document classification, and clause extraction capabilities, as well as OCR, document translation, table digitization, and Q&A functionalities.

On the other hand, ChatGPT is a large language model that employs NLP to generate non-formulaic and creative language from large data sets. With the introduction of GPT-3.5 and the upcoming GPT-4, ChatGPT is expected to improve its language generation and text analysis capabilities.

In summary, these large language models are enhancing the capabilities of businesses in analyzing and understanding their data.
