Verdict

Built from the measurements below

  • Accuracy is too close to call: Gemini 4 Argon scored 83.8% and Grok 4.7 80.0% on the same 80 questions, a gap within what chance alone could produce.
  • Gemini 4 Argon is 4.1× cheaper per question as billed ($0.0062 vs $0.025), reasoning tokens included.
  • Grok 4.7 generates text 1.1× faster: 77 tokens per second against 69.
  • Grok 4.7 starts answering sooner: 1.9 s to the first token, against 3.3 s for Gemini 4 Argon.
  • Gemini 4 Argon accepts more context: 1M tokens against 500k.

Which should you choose?

Choose Gemini 4 Argon for the lower cost per correct answer ($0.0074 against $0.031), shorter outputs (about 558 tokens per question against 3,952) and a 1M-token context window. Choose Grok 4.7 for faster streaming and a quicker first token. The widest subject gap is in law: Gemini 4 Argon answered 6 of 6 correctly, Grok 4.7 4 of 6. With so few questions per subject, treat this as a lead to test on your own prompts, not a result.

Accuracy gap +3.7 points (z = 0.62). A winner is called only when z is at least 1.96, the usual 95% threshold. Speed, latency and price need a 10% margin.
