> All this must mean the Western AI companies are now extremely inference-margin positive.
> So the Chinese labs have thrown a lifeline to the Western loss-making labs, and I just have no clue as to why.
That inference wasn't profitable is a widespread myth.
Analysis based on Kimi K3 suggests that OpenAI and Anthropic have margins well north of 95%: <a href="https://inferencex.semianalysis.com/run/kimi-k3-on-b200" rel="nofollow">https://inferencex.semianalysis.com/run/kimi-k3-on-b200
Over the last months I have seen news that OpenAI made breakthroughs in inference efficiency multiple times.
I have no reason to believe that the leading US labs don't have their own optimizations, or that they learned of this particular optimization from DeepSeek.
> I have no reason to believe that the leading US labs don't have their own optimizations, or that they learned of this particular optimization from DeepSeek.
If they already did, then DeepSeek still made them discount their prices significantly, which eats margin.
The difference matters when they're investing the excess into salaries and bonuses to build the next frontier model.
Seen from a high-level perspective, if Chinese open models are compressing US AI labs' profit margins and those margins fund US AI labs' dominance, then open models are decreasing American AI dominance.

I wonder if margins on GPT-6.1 Sol and Opus 5.5 are now 75% or 90%.
