Models

GPT 4.1 is OpenAI's flagship model for complex tasks. It is well suited for problem solving across domains.

GPT 4.1 mini provides a balance between intelligence, speed, and cost that makes it an attractive model for many use cases.

GPT-4.1 nano is the fastest, most cost-effective GPT 4.1 model.

OpenAI has introduced GPT-4.5, its latest and most advanced AI language model to date. This model enhances pattern recognition and the ability to draw connections, leading to more natural and intuitive interactions. GPT-4.5 is particularly adept at tasks such as writing assistance, programming, and practical problem-solving. Despite its advancements, OpenAI emphasizes that GPT-4.5 is not a frontier AI model and may not surpass specialized versions like o1 or o3-mini in certain areas. The model has been trained using a combination of new supervision techniques and traditional methods, resulting in fewer hallucinations and more emotionally nuanced responses. However, GPT-4.5 is more computationally intensive and expensive to operate compared to its predecessors. Initially, it is available as a research preview for ChatGPT Pro users, with plans to extend access to other user groups in the near future.
