AI Foundations
Understand what AI is, how systems learn, where they fail, and how to judge claims without hype.
Free AI library
1019 plain-English guides, structured learning paths, and an open library — built by an independent 501(c)(3) nonprofit so anyone can understand modern AI.

AI builds custom trip plans by combining your preferences, budget, and dates with live data on flights, hotels, and attractions.
ApplicationsAI in finance apps automatically categorizes spending, forecasts cash flow, and nudges users toward savings goals.
ApplicationsAI accelerates the discovery of new battery materials and the management of existing cells, compressing decades of trial-and-error chemistry into months.
ApplicationsAI uses reinforcement learning to steer the superheated plasma inside fusion reactors in real time, holding it stable long enough to release energy.
ApplicationsAI automates the placement of components on a microchip, a notoriously hard puzzle that determines a chip's speed, power, and size.
Audio AISoundStorm is a Google audio generation model that produces speech and sound in parallel rather than one token at a time, making high-quality audio synthesis…
Audio AIAudioGen is a Meta model that turns text descriptions into realistic environmental sounds and sound effects, like 'dog barking while birds chirp.
Audio AIStable Audio is Stability AI's text-to-audio system that uses latent diffusion to generate music and sound effects, with explicit control over clip length.
Language AIConstrained generation forces a language model to produce output that always conforms to a defined structure, like valid JSON, SQL, or a regular expression.
Language AIWatermarking embeds a hidden, statistically detectable signal into text as a language model generates it, so the output can later be identified…
Visual AILatent Consistency Models (LCMs) are a technique that lets diffusion image generators produce high-quality pictures in just one to four steps instead…
Audio AIKaldi is a free, open-source toolkit that became the dominant research platform for building speech recognition systems.
