Gemini 3.7 flash outputs so many tokens per answer it doesn't matter how fast its TPS is, sol will end up being both cheaper and faster than Gemini. So ppl are paying more for a given task, waiting longer and using a dumber intelligence because "TPS number shiny".
Gemini 3.8 outputs 11k more tokens PER TASK on average in AAII than 3.7 putting it dead last in output tokens per task in the leaderboard.

That said, Luna is the undisputed king here at the moment and is what I use as my workhorse model.
Ps. For the last week I diverged to Luna too, still need to check 3.8 flash.
But 3.6 flash was my go-to model 3 weeks ago and before it was deepseek flash/pro for a while.
None of the claude models seemed cost effective though.
Not sure if you read your own link but Sol 56 high ranks smack between Gemini 3.8 flash medium and high. Gemini 3.8 flash comes in as more expensive per task than Sol 56 high according to artificial analysis.
Luna high is literally 30X cheaper than Gemini 3.8 flash high.
You can limit the model viewer and they're getting better at testing multiple effort levels now: https://artificialanalysis.ai/?models=gpt-5-6-sol-medium%2Cg...
One reason is clear: Sol uses dramatically fewer output tokens than Gemini 38 flash https://artificialanalysis.ai/?models=gemini-3-8-flash%2Cgem...
I also included Sol56 xhigh, which ranks above even Gemini38 high.
I can get extremely dumb models to get our code style correct because of those guard rails and a specific style document.
