So you’ve heard these AI terms and nodded along; let’s fix that

Artificial intelligence is changing the world, and simultaneously inventing a whole new language to describe how it’s doing it. Spend five minutes reading about AI and you’ll run into LLMs, RAG, RLHF, and a dozen other terms that can make even very smart people in the tech world feel insecure.

This glossary is our attempt to fix that. We update it regularly as the field evolves, so consider it a living document, much like the AI systems it describes. AGI — artificial general intelligence — is a nebulous term, but it generally refers to AI that’s more capable than the average human at many, if not most, tasks.

OpenAI CEO Sam Altman once described AGI as the “equivalent of a median human that you could hire as a co-worker,” while OpenAI’s charter defines AGI as “highly autonomous systems that outperform humans at most economically valuable work.” Google DeepMind views AGI as “AI that’s at least as capable as humans at most cognitive tasks.” Confused?
