I go for weeks without topping up my Deepseek balance, and have to top up my OpenAI balance at least every week.

GPT 6 Luna closed the gap significantly for sure (it seems to be about twice as expensive as DS v4.1 Flash), but Deepseek v4.1 Flash is still the best value model and capable enough for almost everything I need to do. Sometimes if it's babbling or can't nail down a solution I switch to Sol for one prompt, get the solution, then switch back to DS. I use 4.1 Flash almost exclusively though for both planning and implementation these days.

I was a heavy Kimi k2.5/2.6 user but since 2.7 Kimi has gone way downhill -- even the previous models. I think they got under heavy load and had to quantise their models to avoid going broke.
