In short
How they differ.
Worked out from the figures below. Prices and specs are the makers' own, read Oct 20, 2026.
- MiniMax-M3 is cheaper per output token: $1.20 against $6 per million tokens, so Grok 4.7 costs 5 times as much.
- MiniMax-M3 reads more at once: a context window of 1M tokens against 500K.
- MiniMax-M3 can be downloaded and run on your own machine; Grok 4.7 can't.
- No independent board we follow ranks both models yet.
