Meta · Apr 2025
Meta's natively multimodal 400B MoE — the largest openly downloadable US-made model, served cheaply across many hosts.
The verdict
Claude Sonnet 4.5 wins 2 of the 2 benchmarks these models share, against 0 for Llama 4 Maverick. On price the gap is dramatic: Llama 4 Maverick works out roughly 14x cheaper per blended million tokens. Llama 4 Maverick also takes 1M of context versus 200K for Claude Sonnet 4.5. And Llama 4 Maverick is open-weights (Llama 4 Community License), so it can be self-hosted — a structural advantage if data control or vendor independence matters.
