How much does ChatGPT cost?ĬhatGPT is still available to use for free, but now also has a paid tier. Throughout the course of 2023, it got several significant updates too, of which more shortly. But it was the full arrival of ChatGPT in November 2022 that saw the technology burst into the mainstream. OpenAI also released a larger and more capable model, called GPT-3, in June 2020. ![]() OpenAI did also previously release earlier GPT models in limited form – its GPT-2 language model, for example, was announced in February 2019, but the company said it wouldn't release the fully-trained model "due to our concerns about malicious applications of the technology". A more advanced GPT-4 model is now available to ChatGPT Plus subscribers. (Image credit: OpenAI)ĬhatGPT is based on a language model from the GPT-3.5 series, which OpenAI says finished its training in early 2022. OpenAI said that the dialog format, which you can now see in the Bing search engine and many other places, allows ChatGPT to "admit its mistakes, challenge incorrect premises, and reject inappropriate requests".Ī paid ChatGPT Plus subscription is available. The interface was, as it is now, a simple text box that allowed users to answer follow-up questions. ![]() A blog post casually introduced the AI chatbot to the world, with OpenAI stating that "we’ve trained a model called ChatGPT which interacts in a conversational way". When was ChatGPT released?ĬhatGPT was released as a "research preview" on November 30, 2022. But ChatGPT was the AI chatbot that took the concept mainstream, earning it another multi-billion investment from Microsoft, which said that it was as important as the invention of the PC and the internet. Google was only too keen to point out its role in developing the technology during its announcement of Google Bard. Interestingly, this transformer architecture was actually developed by Google researchers in 2017 and is particularly well-suited to natural language processing tasks, like answering questions or generating text. Lastly, there's the 'transformer' architecture, the type of neural network ChatGPT is based on. The second and third words show that this model was created using 'generative pre-training', which means it's been trained on huge amounts of text data to predict the next word in a given sequence.Īn illustration from Google's 2017 research paper for the Transformer architecture, which ChatGPT is based on. The 'chat' naturally refers to the chatbot front-end that OpenAI has built for its GPT language model. Let's take a look at each of those words in turn. What does ChatGPT stand for?ĬhatGPT stands for "Chat Generative Pre-trained Transformer", which is a bit of a mouthful. Still, the world is currently having a ball exploring ChatGPT and, despite the arrival of a paid ChatGPT Plus version for $20 (about £16 / AU$30) a month, you can still use it for free too. OpenAI CEO Sam Altman also admitted in December 2022 that the AI chatbot is "incredibly limited" and that "it's a mistake to be relying on it for anything important right now". OpenAI says that its responses "may be inaccurate, untruthful, and otherwise misleading at times". The fact that it can also generate essays, articles, and poetry has only added to its appeal (and controversy, in areas like education).īut early users have also revealed some of ChatGPT's limitations. ![]() This ability to produce human-like, and frequently accurate, responses to a vast range of questions is why ChatGPT became the fastest-growing app of all time, reaching 100 million users in only two months.
