GitHub
AI Train2025

Trains a full ChatGPT-style LLM from scratch on a single 8xH100 node for about $48 in ~2 hours, covering tokenization, pretraining, finetuning, RL, inference, and a web UI in one minimal, hackable codebase you can fork.

A line-by-line PyTorch reimplementation of the Transformer paper as a runnable notebook, where each part of the paper sits next to the code that implements it — turning a dense architecture into something you can read and run end to end.

GitHub
AI API2023

Notebooks and sample apps demonstrating generative-AI workflows on Google Cloud's Vertex AI and Gemini — covering RAG grounding, multimodal demos, function calling, and agent-building examples, with deployment-ready templates for evaluation and production.

GitHub

Teaches generative AI app development through 21 lessons covering LLM basics, prompting, chat, search, image generation, agents, RAG, fine-tuning, small models, and responsible AI.

AI Deploy2023

Compresses, deploys, and serves LLMs via two engines: TurboMind for raw speed, a PyTorch engine for flexibility. Claims ~1.8x vLLM throughput through persistent batching, blocked KV cache, and split-and-fuse; ships 4-bit AWQ and KV-cache quantization.

GitHub

Builds a GPT-style LLM in PyTorch step by step — tokenizer, attention, pretraining, and finetuning — with no external LLM frameworks. Companion code to a Manning book, with bonus chapters on LoRA and modern Llama/Qwen-style architectures.

GitHub
AI API2023

Runnable Jupyter notebooks for building with the Claude API: tool use, RAG, vision, prompt caching, sub-agents, classification, summarization, and integrations like Pinecone and Voyage embeddings. Copy-paste recipes that drop into real projects.

GitHub

Awesome LLM Apps is a curated open-source repository collecting awesome LLM applications built with RAG, AI Agents, Multi-agent Teams, MCP, Voice Agents, and more, using models from OpenAI, Anthropic, Gemini, xAI, and open-source alternatives like Qwen or Llama that can run locally.

GitHub

AI Engineering Hub is a comprehensive GitHub repository offering in-depth tutorials and 93+ production-ready projects on LLMs, RAGs, AI agents, and real-world AI applications for all skill levels.

GitHub

Nine-chapter course teaching prompt engineering for Claude: from basic prompt structure through roles, output formatting, and hallucination control to complete prompts for chatbot, legal, finance, and coding tasks. Runs as editable Jupyter notebooks.

GitHub

Hands-on coding tutorial series for large language models with slides and runnable notebooks covering fine-tuning, prompting, RLHF, safety, steganography, watermarking, multimodal models, GUI agents, and deployment. Community-maintained, free course materials for students and researchers.

GitHub

Official code companion to the O'Reilly book by Jay Alammar and Maarten Grootendorst: 12 chapters of runnable notebooks on tokens, embeddings, Transformers, text classification, clustering, prompt engineering, semantic search, RAG, and fine-tuning.
