Llama 4 Maverick vs Hy4 preview
Updated October 21, 2026. 3 benchmarks have a result for both. Coding is ranked on the Vibe Coding Index; every other board is shown as published.
Decision reading
Llama 4 Maverick scores 18.1 and Hy4 preview 61.6 on the Vibe Coding Index, but no coding benchmark measured both, so the gap is directional, not a ranking.
Pick Llama 4 Maverick when output tokens cost 3.8x less; pick Hy4 preview when the context window is larger, 1.05M against 524K tokens, or when what matters is LegalBench (Vals AI) or MedCode (Vals AI), where it leads.

Questions
Is Llama 4 Maverick better than Hy4 preview for coding?
Llama 4 Maverick scores 18.1 and Hy4 preview 61.6 on the Vibe Coding Index, but no coding benchmark measured both, so the gap is directional, not a ranking. Pick Llama 4 Maverick when output tokens cost 3.8x less; pick Hy4 preview when the context window is larger, 1.05M against 524K tokens, or when what matters is LegalBench (Vals AI) or MedCode (Vals AI), where it leads.
Which is cheaper, Llama 4 Maverick or Hy4 preview?
Llama 4 Maverick costs $0.1875 per million input tokens and $0.6525 per million output tokens; Hy4 preview costs $0.834 and $2.501. Cost per solved task is known for Llama 4 Maverick only.
Which has the bigger context window, Llama 4 Maverick or Hy4 preview?
Hy4 preview, with 1.05M tokens against 524K.
How many benchmarks is the Llama 4 Maverick vs Hy4 preview comparison based on?
3 benchmarks have a result for both models as of October 21, 2026. Llama 4 Maverick's coding index rests on 2 independent benchmarks and Hy4 preview's on 1. Where only one model has a result, the page says so instead of naming a winner.
