DeepSeek V4.1 Flash 1017 in DeepSeek Harness and Claude Opus 5.5 in Claude Code get the same free-rein prompt to design SIGNAL / NOISE, a digital tech magazine in React, TypeScript and Tailwind. Opus took 17 min, DeepSeek 40.

Each side pairs a coding harness with its own model, so harness and model differences are mixed. More Claude Code vs DeepSeek Harness. All harness comparisons.
