Which should you choose?
Choose Llama 4 Maverick for the lower cost per correct answer ($0.001 against $0.027), a quicker first token, open weights you can run yourself and more hosts to choose from on OpenRouter (3 against 1). Choose Muse Wonder for the most accurate answers of the two, faster streaming and a 1M-token context window. The widest subject gap is in engineering: Muse Wonder answered 11 of 15 correctly, Llama 4 Maverick 6 of 14. With so few questions per subject, treat this as a lead to test on your own prompts, not a result.
