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.

CREPE is a deep-learning model that estimates the fundamental frequency (pitch) of a monophonic audio signal directly from its raw waveform.
Audio AIPESQ and STOI are standard objective metrics that score how good processed speech sounds and how understandable it is, without needing human listeners.
Audio AIA vocoder is a tool that takes speech apart into its building blocks and rebuilds it.
CompaniesNVIDIA Cosmos is a family of 'world foundation models' that generate and predict physically realistic video, built to teach robots and self-driving cars…
CompaniesTongyi Lab is Alibaba's AI research group behind the Qwen family of open-weight large language models.
CompaniesWayve's LINGO models pair a self-driving system with natural-language reasoning, so the car can explain what it sees and why it acts.
CompaniesNVIDIA Isaac is a full software-and-hardware stack for building, simulating, and deploying AI-powered robots.
CompaniesSnowflake Arctic is an open large language model built by the data-cloud company Snowflake, tuned for enterprise tasks like SQL generation and coding.
Visual AILaMa (Large Mask inpainting) is a fast, lightweight neural network that fills missing or removed regions of an image cleanly, even when the hole is huge.
Visual AIStable Video Diffusion (SVD) is Stability AI's open foundation model that turns a single still image into a short, smoothly moving video clip.
Visual AILumiere is a text-to-video diffusion model from Google Research that generates an entire video clip at once using a Space-Time U-Net.
FundamentalsScaling laws are empirical formulas showing that a neural network's loss falls predictably as you grow model size, dataset size, and compute.
