Day 5/42: What Is Latent Space?

Yesterday, we talked about embeddings.

Today, we talk about the world they live in.

Latent space is the invisible map where all meanings exist inside a model.

It’s not a database.

It’s not stored facts.

It’s a geometric space where distance = similarity.

Close ideas feel related. Far ones don’t.

When you ask a question, the model doesn’t “look up” an answer.

It navigates this space and pulls patterns from nearby regions.

Missed Day 4? Start there.

Tomorrow, we meet the knobs that shape this entire map: parameters.
