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

CUDA is NVIDIA's platform for writing programs that run on GPUs, unlocking thousands of cores for parallel computation.
TechnicalExplainable AI (XAI) is the toolkit for turning a model's opaque prediction into a human-readable reason.
TechnicalMechanistic interpretability is the effort to reverse-engineer the internal computations of neural networks into human-understandable algorithms.
TechnicalAdversarial examples are inputs perturbed by tiny, often imperceptible changes that cause a model to make confident, wrong predictions.
TechnicalData parallelism trains one model faster by replicating it across many GPUs, with each GPU processing a different slice of the data batch.
TechnicalWhen a model is too large to fit on one GPU, model and pipeline parallelism split the model itself across devices.
TechnicalZeRO (Zero Redundancy Optimizer) eliminates the wasteful memory duplication of data parallelism by sharding optimizer state, gradients, and weights across…
TechnicalExperiment tracking is the practice of systematically recording every machine learning run — its code, data, hyperparameters, metrics, and outputs — so…
TechnicalCI/CD for machine learning extends continuous integration and continuous delivery pipelines to cover not just code, but also data and models.
TechnicalCanary and shadow deployments are two low-risk strategies for releasing a new model or service to production.
TechnicalPrompt caching lets an AI model reuse the computational work it did on a repeated chunk of text instead of reprocessing it every time.
TechnicalA reranker is a second-stage model that re-scores a shortlist of search results for relevance to a query, sharpening the ordering after a fast retriever…
