推定学習コストで並べ替え。
Grok 4 leads with $388M, ahead of GPT-4.5 ($366M) and Grok 3 ($218M).
These figures cover the compute for the final training run only. They exclude the failed runs, the research staff, the data work and the inference infrastructure — in practice, the majority of what a frontier model actually costs its developer.
