When was ChatGPT initially released?

ChatGPT, which is a variant of the GPT (Generative Pretrained Transformer) language model architecture specifically fine-tuned for generating human-like conversational responses, was initially released by OpenAI in November 2022. This release came after substantial progress had been made on earlier iterations of the GPT series, with predecessors including GPT-2 and GPT-3 showcasing impressive language generation capabilities. ChatGPT combined these capabilities with additional fine-tuning techniques to better adhere to conversational norms and provide more contextually relevant answers. Its release marked a significant step forward in natural language processing technology, aiming to simulate human-like conversations across various topics and to demonstrate nuance in understanding and generating text.
