DeepSeek

Efficiency-first open frontier models, with sparse and compressed attention for 1M-token context at a fraction of compute, MoE at 1.6T parameters, aggressive pricing and optimization for Chinese chips. A small, low-hierarchy research team with no KPIs, per founder.

Pushes against
Spending-driven frontier scaling; closed weights.
Now
V4 matches mid-2026 frontier-minus-one models on company-reported benchmarks. Closed a first ~$7B round (2026-06), then paused a second after leaked founder remarks that China still lags and depends on Nvidia (Bloomberg, 2026-07). IPO prep reported.
