DeepSeek

▲ Rising

Chinese AI company backed by a quant firm, releasing efficient models that punch above their weight on benchmarks.

Think of it like

The efficient builder; does more with less, partly through clever architecture.

Example

DeepSeek-67B matches much larger models with a mixture-of-experts architecture; very fast inference.

How it actually works

DeepSeek uses MoE (mixture of experts), which activates only a subset of parameters per token. This lets them build large models with lower inference cost. Recently open-sourced models and released DeepSeek Chat.

For product teams

Efficiency is a moat; lower inference cost means lower margins but huge volume potential.

For engineers

MoE architecture requires careful load-balancing but enables scale without proportional cost increase.
