## AI overview

This explainer places DeepSeek R1, OpenAI's o1 and o3, and DeepSeek V3 in a recent AI timeline. It distinguishes reasoning models from base-model LLMs and explains that AI agents require software to make decisions and interact with the outside world.

## Source excerpt

Is AI making you dizzy? A lot of industry insiders are feeling the same. R1 just came out a few days ago out of nowhere, and then there's o1 and o3, but no o2. Gosh! It's hard to know what's going on. This post aims to be a guide for recent AI develoments. It's written for people who feel like they should know what's going on, but don't, because it's insane out there.
