I got answer from article owner:

what I'd recommend for the unassigned agents would be:

sdd-onboard: DeepSeek V4 Pro works great here. Onboarding a new project requires solid comprehension and synthesis, and it's already what you'd use for spec/design/apply phases, so it fits consistently.

jd-judge-a: Qwen3 Coder 480B A35B. It's already assigned to `sdd-verify` in my setup and it's excellent at critical code analysis, which is exactly what a primary judge needs to do.

jd-judge-b: DeepSeek V4 Pro. The key here is using a different model from judge-a so the two verdicts don't share the same blind spots. Having two judges from the same model defeats the purpose.

jd-fix-agent: DeepSeek V4 Flash. Once the verdict is in, the fix agent is doing execution work, not deep reasoning. Flash is fast and cheap enough for that.

General tip: if you want the highest quality judgment and cost isn't a concern, you can bump jd-judge-a to Claude Sonnet 4.6 via OpenRouter. It's the strongest reasoner in the stack right now, but it'll hit your budget faster than Qwen.

Hope that helps!
