About GPT-4 (Generative Pre-trained Transformer 4) is a large-scale unsupervised language model, yet to be released by OpenAI. GPT-4 is the successor to GPT-3 and part of the GPT-n series of natural language processing models, and was trained on a dataset of 45TB of text to produce human-like text generation and understanding capabilities. Unlike most other NLP models, GPT-4 does not require additional training data for specific tasks. Instead, it can generate text or answer questions using only its own internally generated context as input. GPT-4 has been shown to be able to perform a wide variety of tasks without any task specific training data such as translation, summarization, question answering, sentiment analysis and more.	About GPT-5.5 Instant is ChatGPT’s updated default model, designed to be smarter and more accurate, with clearer, more concise answers that feel better tailored to each user. Built as a daily driver for hundreds of millions of people, this update makes everyday interactions more useful and enjoyable through stronger and tighter answers across subject areas, a more natural conversational tone, and better use of shared context when personalization can help. GPT-5.5 Instant is more dependable, with significant improvements in factuality, especially in domains where accuracy matters most, including medicine, law, and finance. It is more capable across everyday tasks, with improvements in analyzing photo and image uploads, answering STEM-related questions, and deciding when to use web search to provide a more useful answer. Responses are tighter and more to the point without losing substance, while keeping the warmth and personality that makes ChatGPT enjoyable to use.
