Output tokens cost $6.00 per million on Grok 4.5 and $1.15 per million on MiniMax M2.1. Input tokens cost $2.00 per million on Grok 4.5 and $0.29 per million on MiniMax M2.1. Cached input tokens are billed at $0.50 per million on Grok 4.5 and $0.29 per million on MiniMax M2.1. Context lengths are 500,000 tokens on Grok 4.5 and 204,800 tokens on MiniMax M2.1. Time to first token (TTFT) measured on AIHubMix is 1.7s on Grok 4.5 and 0.6s on MiniMax M2.1. Measured output throughput is 25.4 tok/s on Grok 4.5 and 87.6 tok/s on MiniMax M2.1. On the LMArena coding leaderboard Grok 4.5 scores 1523 and MiniMax M2.1 scores 1439.
Grok 4.5
MiniMax M2.1Grok 4.5 was trained on datasets spanning knowledge in coding, science, engineering, and math. With both intelligent and efficient reasoning, Grok 4.5 excels at real engineering tasks and exceeds comparable leading models at these tasks.
MiniMax-M2.1 redefines efficiency for intelligent agents. It is a compact, fast, and cost-effective MoE model with a total of 230 billion parameters and 10 billion active parameters, designed for top performance in coding and intelligent agent tasks while maintaining strong general intelligence. With only 10 billion active parameters, MiniMax-M2 delivers the complex end-to-end tool usage performance expected from today's leading models, but in a more streamlined form factor, making deployment and scaling easier than ever before.
