Grok 4.1 Fast vs Llama 4 Maverick
Benchmarks, API pricing and specs, head to head. Data updated 2026-06-10.
xAI · Nov 2025
A 2M-token context window for $0.20 per million input tokens — the cheapest long-context frontier offering anywhere.
Meta · Apr 2025
Meta's natively multimodal 400B MoE — the largest openly downloadable US-made model, served cheaply across many hosts.
The verdict
These two models don't yet share verified results on the benchmarks we track, so judge them on specs, pricing and intended use. Grok 4.1 Fast is about 1.5x cheaper per blended million tokens (3:1 input:output mix). Grok 4.1 Fast also takes 2M of context versus 1M for Llama 4 Maverick. 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.
