What each one is
Annotated Paper Implementations
labml.ai's collection of deep learning papers implemented in PyTorch, with the explanation printed alongside the code — transformers, diffusion, RL, optimisers and more.
- Paper and code side by side, always in sync
- 60+ architectures, all runnable
- The fastest way to understand a new paper
OpenAI Cookbook
A collection of working code recipes for LLM tasks — embeddings, RAG, function calling, evaluation. Written for the OpenAI API, but the patterns apply to any OpenAI-compatible endpoint, including your local models.
- Working code, not pseudo-code
- The patterns work with local models too (Ollama, vLLM)
- Covers evaluation, which most guides skip
