vs boards won of 6 shared
Decision reading
Claude Opus 5.5 scores 92.2 and Qwen3 Coder 30B A3B Instruct 60.4 on the Vibe Coding Index, but no coding benchmark measured both, so the gap is directional, not a ranking.
Pick Claude Opus 5.5 when the context window is larger, 1M against 262K tokens, or when what matters is AA Intelligence Index or Humanity's Last Exam (Artificial Analysis run), where it leads; pick Qwen3 Coder 30B A3B Instruct when output tokens cost 71.4x less.
