The Idiot's Blog

nvidia-smi says your GPU is 80% busy. It doesn't tell you if that's Tensor cores, CUDA cores, or just memory transfers. gpu-core does.

Build your own backpropagation engine in ~100 lines of Python. The secret sauce behind every neural network.

Build a working GPT in PyTorch. Tokenizer, self-attention, transformer blocks, training loop. Generate text.

Build an image classifier in PyTorch. Upload a photo, get a prediction. Your first real AI app.

Fine-tune a language model to write in any style. Poems, code, tweets, you pick the voice.

Put your AI model on the internet. Build a web app with Gradio and deploy it for free.
