Learn by playing
All simulators →Transformer Lab
Tokenize with BPE, watch attention heads, rotate positions with RoPE, size a KV cache, route tokens to experts and quantize weights.
RAG Lab
Chunk a handbook, search it by meaning, fuse BM25 with dense retrieval, rerank, measure recall and NDCG, and keep the index fresh.
Deep Learning Lab
Build neural networks from scratch. Explore 3D error surfaces, optimizers, backpropagation, overfitting and convolutions.
Image Processing Lab
Sampling, filtering, Fourier transforms, segmentation, SIFT and HOG, applied to a live image you can change.
Electronics Lab
Simulate circuits, diodes, transistors and op-amps. Plot V-I curves, load lines and Bode plots, with a live oscilloscope.
Computer Networks
Design topologies, configure routers and watch packets travel hop by hop through routing, DHCP and the OSI layers.
Supply Chain
Run a business end to end: orders, warehouse, transport and finance. Sign in to save your progress.
