01 — Verdict

Too close to call

It is close. Our weighted score puts them within a point (Llama 3.3 Nemotron Super 49B v1.5 50/100, Qwen3 Coder Flash 50/100), so choose by what matters most for your work: Llama 3.3 Nemotron Super 49B v1.5 on price and Qwen3 Coder Flash 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.
