Summary
ChatGPT is a large language model developed by OpenAI that has many different models which are designed to complete different tasks.
OpenAI has provided guidance on which models should be used for each type of task to ensure users get the best performance and speed from the model, and to avoid encountering AI hallucinations, poor performance, or slow output.
For routine or generic tasks, GPT-4o is ideal and is quick and suited to multitasking, whereas GPT-4.5 is best suited to creative tasks requiring human-like creativity, emotional intelligence, and intuition for effective communication.
For technical tasks, the o4-mini model is fast and suited to simpler tasks, whereas the o4-mini-high model is suited to more advanced and complex tasks, particularly in the areas of coding, maths, and scientific topics.
OpenAI o3 is suited to complex tasks involving multiple steps, whereas o1 pro mode is a slower model designed for specificity and complexity, suitable for high-risk industries such as law, finance, and healthcare.
