What is Apple Intelligence?
Apple Intelligence is the name Apple has given to its generative AI tools, which are gradually being introduced into certain iPhones, iPads and Macs: the iPhone 16 line, iPhone 15 Pro models, and Macs and iPads with M-series chips. The first set of features will be in beta as of October 2024 as part of iOS 18.1, iPadOS 18.1 and MacOS Sequoia 15.1, and will include some writing tools, a Clean Up tool for photos and an upgrade to Siri.
Learn moreWhat is GPT-4o and how does it relate to ChatGPT?
GPT-4o (the o is for "omni") is the May 2024 update from OpenAI to the AI engine that powers ChatGPT, and it's two times faster than GPT-4 Turbo, which debuted in late 2023. Your prompts can include any combination of text, audio, images and video, and the responses generated will be able to include similar combinations. According to OpenAI, GPT-4o brings "GPT-4-level intelligence to everything" including the free version of ChatGPT, though paying customers will get five times the capacity. New real-time speech functionality means you can interact with ChatGPT in a more conversational way.
Learn moreWhat are AI tokens and how do they work?
Tokens are pieces of words that an LLM evaluates to understand the broader context of a query. Each token is made up of roughly four characters in English. They can be letters, numbers, spaces, special characters and more. For example, the sentence "You miss 100% of the shots you don't take" consists of 11 tokens. (If you swap out the percentage symbol for the word "percent," the count increases to 13 tokens.) Tokens are used both as inputs and outputs. When you input a query into an AI model, the model breaks down the words into tokens, analyzes them and delivers a response in tokens that are then converted into words you'll understand.
Learn moreWhat is an AI hallucination?
A generative AI model "hallucinates" when it delivers false or misleading information. This happens because of how the models are trained, on massive amounts of data, like articles, books, code and social media posts. In creating its response to a prompt, the AI makes inferences about what words should come next, but it lacks contextual information so it may generate wording that seems plausible but isn't true. Hallucinations can also result from improper training and/or biased or insufficient data, which leave the model unprepared to answer certain questions.
