Which should you choose?

Choose gpt-oss-120b for the lower cost per correct answer ($0.00021 against $0.0021), a quicker first token, shorter outputs (about 546 tokens per question against 2,355) and more hosts to choose from on OpenRouter (23 against 5). Choose Hy3 for faster streaming and a 262k-token context window. The widest subject gap is in law: Hy3 answered 4 of 6 correctly, gpt-oss-120b 1 of 6. With so few questions per subject, treat this as a lead to test on your own prompts, not a result.

Accuracy gap +0.0 points (z = 0.00). A winner is called only when z is at least 1.96, the usual 95% threshold. Speed, latency and price need a 10% margin.
