Specialist Training
A DeepSeek-V4 post-training pattern that sharpens separate capability areas before they are merged back into the final stack.
One general post-training pass can blur domain-specific strengths. Specialist training keeps certain domains or tasks sharper by letting them mature with more focused data and objectives before the final system is assembled.

What It Is
Specialist training is the part of the V4 story where high-value domains are trained with more targeted supervision rather than only with one blended generic pass.Why It Exists
It aims to preserve strong performance in demanding subdomains such as reasoning-heavy or verifiable tasks.How It Works
Data is organized around specialist capability pockets, those specialists are improved, and the results are folded back into the broader stack.Specialist Training flow
