Grok 4.6 vs Sol 5.6 vs Opus 5:

So Grok 4.6 is incredibly expensive in that comparison? It's double the cost of Sol 5.6 Low and still nearly double of the cost of 5.6 Medium (which scores +6% over Grok).

Yeah, Sol models have higher in/out cost but are incredibly token efficient.

Also, in those tests Sol Low did better, but you can also compare the price vs Sol High, then it's getting a bit closer.

So Grok 4.6 is still not the best choice when paying API rates, but they are improving fast.

Also, the more important difference is that sol is a lot faster.
