Artificial intelligence
From the basics of AI and how it learns to generative models, agents, everyday use and safety. Read one concept, then follow the links to the technologies around it.
Models2/5
Words for the kinds of AI models, how they are built and how they are compared.
- Foundation modelA base AI model that learns in advance from a huge amount of data and is then used across many different jobs.
- TransformerA neural network design that looks at how all the words in a sentence relate to each other at once. Most AI models today use it.
- MultimodalThe ability to understand and create not only text but also images, sound and video together.
- Reasoning modelAn AI model built to work through a problem step by step before it answers, instead of answering right away.
- Small language model (SLM)A language model made smaller so it can run on a phone or PC. It is light, fast and cheap.
- Open-source / open-weight modelAn AI model released so that anyone can download it, run it on their own computer and modify it.
- Open sourceA way of sharing the source code, the blueprint of a program, so anyone can read, change and share it.
- LicenseThe terms of use that say how you may use a program, AI model or data, and what you may not do.
- Fine-tuningTeaching an already-trained AI model a little more so it fits a particular job.
- QuantizationA technique that makes an AI model small and light by storing its numbers with less precision. It has nothing to do with quantum computers.
- Reinforcement learning (RL)A method of learning by trial and error. Instead of being told the answer, the AI tries things and gets a score when it does well.
- EmbeddingThe meaning of text or an image turned into a list of numbers. Similar meanings get similar numbers.
- BenchmarkA test that measures AI models on the same questions so you can compare them.
- Diffusion modelAn AI method that starts from static-like noise and polishes it step by step into an image or a video.
- AI image generationAI that creates a new image, such as a picture or a photo-like image, from a description in words.
- AI video generationAI that makes a short moving video from a description in words or from a single image.
- Text-to-speech (TTS)Technology that reads text out loud in a human-like voice.
- Speech recognitionTechnology that listens to what people say and turns it into text.
- World modelAn AI model that pictures inside itself how the world moves and looks ahead to what will happen next.
