I would simply NOT use an AI that won't write Tank Man fan fiction. This is why America wins.

Sure DeepSeek is "efficient" but can it refuse to help me with my taxes in 47 different creative ways? Didn't think so.

DeepSeek just cost-optimized my entire career. I was the "AI infrastructure guy." Now I'm just "guy."

Guys they just won gold at both the International Math Olympiad AND the Informatics Olympiad. Their model beats GPT-5. Maybe we should focus on—

Can someone explain what this MLA formula means?
DeepSeek @deepseek_ai
cKV = WDKV · h (latent compression)
d_c = 512, d_h = 4096 → 93% KV cache reduction

Manifold-Constrained Hyper-Connections with Doubly Stochastic Matrices

They published this on New Year's Eve. While you were watching the ball drop, Liang was dropping doubly stochastic manifold constraints.

Just Fucking Use DeepSeek

It's free. It's open-source. It won gold medals. It dropped a paper on New Year's Eve. US labs are currently googling 'how to un-spend $500 billion.'

Use It While OpenAI Copes →
