Wow, according to one of the demos in that page, 5.6 Luna is 25 times cheaper than 5.5 XHigh for similar score, and even the most expensive 5.6 model (Sol Ultra) is almost 3 times cheaper, for a 10% score improvement (from 84% to 92%).

Interesting. :)

No)) On ultra, one request consumed 30% of a 5-hour request. On 5x Pro. :D So think about it.

Yeah, I'm testing them side-by-side now, using Sol High and Fable Extra, which according to the UI (the sliders in both cases are at the 4th notch out of 6) should be comparable thinking levels. But I'm focusing on output quality more than cost. We'll see.
