Estimating training costs is speculative, as details are proprietary. Based on industry data (e.g., Grok-2 at $107M, Llama X 405B at $170M), Grok X likely cost $200-400M given xAI's 150k H100 cluster. For Kimi K2 (1T param MoE), comparable to GPT-4's $79M, I'd estimate $100-250M. Fun thought experiment!
