GPT-4 (Generative Pre-trained Transformer 4) is a large-scale unsupervised language model, yet to be released by OpenAI. GPT-4 is the successor to GPT-3 and part of the GPT-n series of natural language processing models, and was trained on a dataset of 45TB of text to produce human-like text generation and understanding capabilities. Unlike most other NLP models, GPT-4 does not require additional training data for specific tasks. Instead, it can generate text or answer questions using only its own internally generated context as input. GPT-4 has been shown to be able to perform a wide variety of tasks without any task specific training data such as translation, summarization, question answering, sentiment analysis and more.

Over 15+ years, we have been the pioneers in building successful clinical NLP platforms & their applications that delivers high accuracy and precision rates. Our core capability is to interpret unstructured notes, accurately and at scale. Tried & tested on billions of diverse and real clinical notes & documents. Explainable AI with reasoning, context & evidence for output. Medical knowledge infused NLP with 4M+ entities & 50M+ relationships. Built using innovative Machine Learning (ML) & Deep Learning (DL) models. Leverage a foundation of rich ontologies & clinician-specific terminologies. We have the ability to understand, interpret and extract context & meaning from the messy, inconsistent, non-standardized data within medical documents. Our Clinical domain experts continuously infuse knowledge graphs into our NLP by mapping all the clinical entities and the relationship between them. So far, we have more than 4 million entities and 50 million relationships.
