Command A vs Gemma 3 12B
Updated October 21, 2026. 38 benchmarks have a result for both. Coding is ranked on the Vibe Coding Index; every other board is shown as published.
Decision reading
Neither model has a coding score yet, so the two cannot be ranked on coding.
Command A has the edge where the context window is larger, 256K against 131K tokens, and where what matters is AA Math Index or AIME 2025 (Artificial Analysis run), where it leads.
