So, Deepseek 3.1 from their own platform:

Input $0.28 / 1M tokens cache miss Output $0.42 / 1M tokens

Via synthetic (which otherwise looks cool):

Input $0.56/mtok Output $1.68/mtok

So 2-3 better value through https://platform.deepseek.com

(Granted Synthetic gives you way more models to choose from, including ones that don't parrot CPC/PLA propaganda and censor)

I'm using CC + GLM 4.6 from Synthetic and results are top notch for $60/mo, speed is fast and servers are close to home than z.ai
