The primary focus of this text is the GPT-4, which is the latest version of the Generative Pretrained Transformer (GPT) series developed by OpenAI[3]. GPT-4 is a grande modelo linguístico[1], speculated to possess 1.76 trillion parameters. It’s designed to enhance creative writing, instruction handling, and even facilitate multimodal functionality. The model’s improved abilities have found application in various sectors, including healthcare and education, despite certain limitations like potential hallucinations and lack of transparency. OpenAI has also incorporated GPT-4 in different software such as ChatGPT Plus and Microsoft[2]’s various products. However, the closed nature of GPT-4 has sparked criticisms from the AI community, primarily due to difficulty in researching its bias and safety.
Generative Pre-trained Transformer 4 (GPT-4) is a multimodal grande modelo linguístico 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.
