GPT-4 - 2026 Pricing, Features, Reviews & Alternatives

GPT-4 is OpenAI's most advanced language model, producing safer and more useful responses than previous versions. It is more creative and collaborative than ever before, capable of generating, editing, and iterating on a wide range of creative and technical writing tasks, such as composing songs, writing screenplays, or learning a user's writing style.

GPT-4 can also accept images as inputs and generate captions, classifications, and analyses. Its ability to handle over 25,000 words of text makes it suitable for long-form content creation, extended conversations, and document search and analysis. Compared to GPT-3.5, GPT-4 surpasses it in advanced reasoning capabilities, scoring in the 90th percentile on the Uniform Bar Exam and the 99th percentile on the Biology Olympiad.

Significant efforts have been made to improve the safety and alignment of GPT-4. It is 82% less likely to respond to requests for disallowed content and 40% more likely to produce factual responses than GPT-3.5. This was achieved through training with more human feedback, including from ChatGPT users and over 50 experts in AI safety and security, as well as continuous improvement from real-world use and GPT-4-assisted safety research. GPT-4 is available on ChatGPT Plus and as an API for developers to build applications and services.
