Grok 4.1 Fast vs MiniMax M2
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.
MiniMax · Oct 2025
A 10B-active MoE tuned purely for agents and code — striking capability-per-active-parameter at rock-bottom prices.
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 1.9x cheaper per blended million tokens (3:1 input:output mix). Grok 4.1 Fast also takes 2M of context versus 205K for MiniMax M2. And MiniMax M2 is open-weights (MIT), so it can be self-hosted — a structural advantage if data control or vendor independence matters.
