# train-llm-from-scratch vs ai-engineering-from-scratch

train-llm-from-scratch and ai-engineering-from-scratch share 5 technologies: torchaudio, torchvision, torch, tiktoken, and datasets. Both are written in Python.

- [FareedKhan-dev/train-llm-from-scratch](https://seerepo.com/r/FareedKhan-dev/train-llm-from-scratch): A straightforward method for training your LLM, from downloading data to generating text.
- [rohitg00/ai-engineering-from-scratch](https://seerepo.com/r/rohitg00/ai-engineering-from-scratch): Learn AI Engineering! Learn it. Build it. Ship it for others.

## What they share and what sets them apart

- In common: torchaudio, torchvision, torch, tiktoken, datasets
- Only in train-llm-from-scratch: h5py
- Only in ai-engineering-from-scratch: Anthropic, OpenAI, Hono, @mastra/libsql, matplotlib, accelerate, librosa, strands-agents, tokenizers, transformers, scikit-learn, MCP, google-adk, LangChain, pillow, shiki, Zod, @hono/node-server, @mastra/core

- Size: Lines written by people and agents, without generated ones; code files, without tests.
- Who writes it: A commit counts as AI's when it carries its signature: a Co-Authored-By line, its author name or the merge of its branch.
- Activity: From GitHub and its history, on the day SeeRepo read it.
- Tests: The files that test the code, and the share of code files a test imports.
