Benchmarks, API pricing and specs, head to head. Data updated 2026-06-10.
OpenAI · Nov 2025
A November 2025 update to GPT-5 with adaptive reasoning that spends thinking tokens only when a task needs them.
Meta · Apr 2025
Meta's natively multimodal 400B MoE — the largest openly downloadable US-made model, served cheaply across many hosts.
The verdict
GPT-5.1 wins 1 of the 1 benchmarks these models share, against 0 for Llama 4 Maverick. On price the gap is dramatic: Llama 4 Maverick works out roughly 8.3x cheaper per blended million tokens. Llama 4 Maverick also takes 1M of context versus 400K for GPT-5.1. 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.
