Embeddings — The Secret Trick Behind AI Search
When you search a chat history or use a 'similar to this' feature, embeddings are doing the work.
What to actually do
- Used in: chat memory, recommendation systems, semantic search, RAG
- 'Dog' and 'puppy' end up close in number-space, even though the letters are different
- Spotify, Netflix, TikTok all use embeddings under the hood
Key terms in this lesson
The big idea: Embeddings turn meaning into math. That math is how AI 'knows' two things are similar.
