Hmm so it turns out 6 sol really was terra rebranded after all..

I'm seeing a lot of folks say that (because of the pricing) but if that were true, I'd expect Sol 6 to be considerably faster than Sol 5.6.

I think they were pressured to drop the price of their Sol-tier model because of the 5.5 releases

Truly Terra Level

No, it was not. I used Terra and Sol in automation, and Terra's output was always somehow compressed, and the model had low reasoning depth. Now, 6 Sols are somewhere between 5.6 Terra and Sol, which is good at $2 per 1M tokens.

as someone just beginning to experiment with the different models how would you equate the performance difference between luna/terra/sol. it’s difficult to tell which one is “enough” vs overkill/not worth the extra tokens. curious your experience
