OpenAI created AI in 2015 to develop AI that could avoid risks technology brings. The first big break came in 2018 with their very first GPT-1 capable of generating text. Next came the more advanced GPT-2 in 2019, with 1.5 billion parameters and natural human-like responses.
GPT-3 was released in 2020 with 175 billion parameters and capable of generating deep and natural text. It was a success and was used in customer service and content creation. OpenAI improved GPT-3 into GPT-3.5 so it was better at handling dialogues.
ChatGPT was developed from GPT-3.5 and was built specifically for conversation, engaging with users on a deeper level. Its appeal started to spread, sharing stories, jokes, and creative experiments on social media.
Microsoft invested $1 billion into OpenAI as they saw an opportunity to make ChatGPT available on a larger scale. Bing integrated ChatGPT in a more conversational search experience, enabling users to interact directly with ChatGPT for a better search experience.
OpenAI has been actively working on improving ChatGPT's accuracy and reliability, including improving factual accuracy, preventing ‘jailbreaking’, and releasing GPT-4 for ChatGPT Plus subscribers in 2023.
Feedback from millions of users has helped OpenAI see where improvements are needed for the updates and tweaks that make ChatGPT a dependable tool.
