Learn AI as it actually is this week.

ChatGPT

OpenAI’s consumer and business chat assistant. A common first place people try writing, Q&A, and light coding help.

Claude

Anthropic’s AI assistant for chat, writing, and analysis. Available on the web and via API.

Gemini

Google’s assistant family, used in the Gemini app and across some Google products.

Cursor

An AI-centered code editor. You stay in a project; the assistant can read and edit files with your permission.

GitHub Copilot

GitHub’s coding assistant, used inside editors and on github.com. It suggests and explains code in your repository.

Hugging Face

A public hub for model weights, datasets, and demos. Also a place to run and share models without building hosting from scratch.

OpenAI

OpenAI Academy

OpenAI’s own learning site for using ChatGPT and related products at work. We link the official catalog; Learn Lumin does not host the lessons or issue OpenAI’s certificates.

Anthropic

Claude Academy

Anthropic’s learning site for working and building with Claude. Collections and course pages live on academy.claude.com — not on this hub.

Hugging Face’s published course on large language models, on their Learn site. Open the official chapters there; this card is only a citation plus original context.

Hugging Face

AI Agents Course

Hugging Face’s agents course (units on their Learn site). Use it to see how they currently explain tools and agent loops — then check a real product before you copy a pattern.

Hugging Face

Community Computer Vision Course

Hugging Face’s community computer-vision course. It is about images and vision models, not chat assistants. Read their units for current libraries and notebooks.
