o3 Pro vs Qwen3 Coder 30B A3B Instruct
Updated October 21, 2026. 2 benchmarks have a result for both. Coding is ranked on the Vibe Coding Index; every other board is shown as published.
Decision reading
o3 Pro scores 84.9 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 o3 Pro when what matters is AA Intelligence Index or GPQA Diamond (Artificial Analysis run), where it leads; pick Qwen3 Coder 30B A3B Instruct when output tokens cost 285.7x less, or when the context window is larger, 262K against 200K tokens.
