01 — Verdict

Too close to call

It is close. Our weighted score puts them within a point (Grok 4.20 (Non-Reasoning) 52/100, Mistral Large 3 52/100), so choose by what matters most for your work: Mistral Large 3 on price and Grok 4.20 (Non-Reasoning) for long inputs. The score weighs price 50%, inputs & features 30%, context window 20%. None of the shared benchmarks cover every model here yet, so capability is left out of this verdict.
