OpenAI launches GPT-4o mini, which will replace GPT-3.5 in ChatGPT

GPT-4o mini will reportedly be multimodal like its big brother (which launched in May), interpreting images and text and also being able to use DALL-E 3 to generate images.

OpenAI told Bloomberg that GPT-4o mini will be the company’s first AI model to use a technique called “instruction hierarchy” that will make an AI model prioritize some instructions over others (such as from a company), which may make it more difficult for people to perform prompt injection attacks or jailbreaks that subvert built-in fine-tuning or directives given by a system prompt.
