Thinking without a transcript.
Deliberation that happens before language.
A written chain of thought is readable, and expensive: every step generated, carried in context, billed as output. Eugeny deliberates in a continuous latent space instead, spending its compute on the problem rather than on narrating it, and answering with the depth the question deserves.
The result is a model that can work hard on a hard question and still answer a simple one in a breath.
