Which should you choose?
Choose Command A for the lower cost per correct answer ($0.015 against $0.026), a quicker first token and shorter outputs (about 616 tokens per question against 2,408). Choose Qwen3.8 2.4T A95B for faster streaming, a 1M-token context window and more hosts to choose from on OpenRouter (5 against 1). The widest subject gap is in science: Qwen3.8 2.4T A95B answered 21 of 30 correctly, Command A 12 of 30. With so few questions per subject, treat this as a lead to test on your own prompts, not a result.
Accuracy gap -12.5 points (z = -1.58). We call a winner only when z is at least 1.96, the usual 95% threshold. Speed, latency and price need a 10% margin.
