On Thursday, OpenAI announced the launch of GPT-4o mini, a new, smaller version of its latest GPT-4o AI language model that will replace GPT-3.5 Turbo in ChatGPT, reports CNBC and Bloomberg. It will be available today for free users and those with ChatGPT Plus or Team subscriptions and will come to ChatGPT Enterprise next week.

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.
