We performed several iterations of this process. ChatGPT is fine-tuned from a model in the GPT‑3.5 series, which finished training in early 2022. You can learn more about the 3.5 series here . ChatGPT and GPT‑3.5 were trained on an Azure AI supercomputing infrastructure.
GPT-4 is capable of handling over 25,000 words of text, allowing for use cases like long form content creation, extended conversations, and document search and analysis.
In line with our mission, we are focused on advancing AI technology and ensuring it is accessible and beneficial to everyone. Today we are introducing our newest model, GPT‑4o, and will be rolling out more intelligence and advanced tools to ChatGPT for free.
