In my niche Redactle puzzle solving benchmark [1] I noticed Gemini 3.8 flash is slightly faster than 3.7 flash. They both smoke every model I've tested. I have not yet run 3.5 flash. Gemini models are great at this task because they seem to have exact Wikipedia text baked into the weights. When I rewrite the wiki text a bit it's not able to one-shot the game so much.
