Grok 4.5 is cheap af.
it's Opus-level frontier intelligence at ~25% of its price, just a little above the price range of Chinese open-source models.
I've never been as impressed by Grok.
let's hope it holds up in practical use.
Grok 4.5 is efficient and fast. It uses half as many tokens per task, delivers higher tokens per second, and costs less than half as much as comparable models, at $2/M input and $6/M output tokens.
