GPT-4, the most recent iteration of OpenAI’s Generative Pretrained Transformer (GPT) series, is the central subject of this passage. This expansive language model, rumored to contain 1.76 trillion parameters, has been engineered to boost creative writing, handle instructions efficiently, and even support multimodal functionality. Despite certain drawbacks like possible hallucinations and a lack of transparency, GPT-4’s enhanced capabilities have been utilized in diverse fields such as healthcare and education. It’s also been integrated into various software like ChatGPT Plus and a range of Microsoft’s products. Nevertheless, the AI community has voiced criticisms over GPT-4’s closed nature, mainly due to challenges in investigating its bias and safety.
Generative Pre-trained Transformer 4 (GPT-4) is a multimodal large language model created by OpenAI, and the fourth in its series of GPT foundation models. It was launched on March 14, 2023, and made publicly available via the paid chatbot product ChatGPT Plus, via OpenAI's API, and via the free chatbot Microsoft Copilot. As a transformer-based model, GPT-4 uses a paradigm where pre-training using both public data and "data licensed from third-party providers" is used to predict the next token. After this step, the model was then fine-tuned with reinforcement learning feedback from humans and AI for human alignment and policy compliance.

Observers reported that the iteration of ChatGPT using GPT-4 was an improvement on the previous iteration based on GPT-3.5, with the caveat that GPT-4 retains some of the problems with earlier revisions. GPT-4, equipped with vision capabilities (GPT-4V), is capable of taking images as input on ChatGPT. OpenAI has declined to reveal various technical details and statistics about GPT-4, such as the precise size of the model.
