Experiment
The AI Lab
Interactive labs where you manipulate the controls and observe what happens. Each lab computes for real in your browser, no accounts, no servers. More are rolling out.
All labs
Tokenizer Playground
LiveSee how text becomes tokens and token IDs.
Sampling & Temperature
LiveExplore temperature, top-k and top-p on token probabilities.
Gradient Descent Simulator
LiveTune the learning rate and starting point on a loss landscape.
Attention Visualizer
LiveInspect which tokens attend to which, with scaled dot-product.
Neural Network Playground
LiveAdd neurons, layers and activations and watch a network learn.
Q-Learning Gridworld
LiveWatch tabular Q-learning find a path to the goal by trial and error.
Embedding Explorer
LiveEnter sentences and see their positions in a vector space.
Vector Search Simulator
LiveWatch nearest-neighbour retrieval over an embedded corpus.
RAG Pipeline Simulator
LiveTrace a query through retrieval, reranking and generation.
Agent Loop Simulator
LiveStep through goal, plan, tool call, observation and reflection.
GPU / VRAM Calculator
LiveEstimate whether a model fits given precision and context.
Evaluation Playground
LiveMove the threshold and watch precision, recall and F1 change.
