AI is Compression

We view intelligence as the ability to compress vast amounts of information into compact representations and, from that compression, recover information and derive new insights.

02

Thinking via Compression

We apply the same principle to how we think. We compress complex problems by questioning assumptions and keeping only what must be true, then reason from that core to derive new insights.
