Verdict
Built from the measurements below
- Accuracy is too close to call: Hy3 scored 58.8% and Qwen3.7 Plus 60.0% on the same 80 questions, a gap within what chance alone could produce.
- Hy3 is 2.6× cheaper per question as billed ($0.0012 vs $0.0033), reasoning tokens included.
- Hy3 generates text 1.5× faster: 96 tokens per second against 62.
- Qwen3.7 Plus starts answering sooner: 1.1 s to the first token, against 1.7 s for Hy3.
- Qwen3.7 Plus accepts more context: 1M tokens against 262k.
Which should you choose?
Choose Hy3 for the lower cost per correct answer ($0.0021 against $0.0054), faster streaming, open weights you can run yourself and more hosts to choose from on OpenRouter (5 against 1). Choose Qwen3.7 Plus for a quicker first token and a 1M-token context window. The widest subject gap is in humanities & social science: Qwen3.7 Plus answered 9 of 9 correctly, Hy3 6 of 9. With so few questions per subject, treat this as a lead to test on your own prompts, not a result.
Accuracy gap -1.2 points (z = -0.16). We call a winner only when z is at least 1.96, the usual 95% threshold. Speed, latency and price need a 10% margin.
