Output tokens cost $6.00 per million on Grok 4.5 and $3.30 per million on MiMo V2 Pro. Input tokens cost $2.00 per million on Grok 4.5 and $1.10 per million on MiMo V2 Pro. Cached input tokens are billed at $0.50 per million on Grok 4.5 and $0.22 per million on MiMo V2 Pro. Context lengths are 500,000 tokens on Grok 4.5 and 1,000,000 tokens on MiMo V2 Pro. Time to first token (TTFT) measured on AIHubMix is 2.2s on Grok 4.5 and 1.7s on MiMo V2 Pro. Measured output throughput is 27.7 tok/s on Grok 4.5 and 41.3 tok/s on MiMo V2 Pro. On the LMArena coding leaderboard Grok 4.5 scores 1523 and MiMo V2 Pro scores 1503.
Grok 4.5
MiMo V2 ProGrok 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.
Xiaomi MiMo-V2-Pro is built for high-intensity agent work scenarios in the real world. It has over 1 trillion total parameters (42B active parameters), employs an innovative hybrid-attention architecture, and supports an ultra-long 1M-token context length. On top of a powerful model foundation, we continuously scale compute across broader agent scenarios, further expanding the intelligent action space and achieving significant generalization from Coding to Claw.
