Built a coding workstation around V4 Pro — the reasoning_content chain of thought is doing something specific that flat models can't

I've been using DeepSeek V4 Pro as the primary coding model in Atlarix, a desktop AI workstation I build out of Nairobi. Not here to pitch it, just want to share something I noticed that's specific to V4 Pro vs other models I run. The thinking model behaviour changes how multi-file refactors go. Before V4 Pro proposes any edit, the reasoning trace catches cross-file dependency issues, import chains, type mismatches across modules, things that a flat completion model just guesses at and gets wrong half the t
