Grok 4.5 is the best-value LLM on the market.
You pretty much get Opus 4.7 intelligence at ~2-3x speed, 1/3 the cost, and superior token efficiency.
I wasn't expecting ground-breaking Fable intelligence with this release, and tbh, Grok doesn't need it to achieve great product-market fit.
This is insane value, and I'm personally valuing token efficiency much more these days.
(of course I'm still opting to use Fable, GPT-5.6, etc, but these cost-efficient models are becoming an increasingly important part of my daily stack)
