What is the cost of access like for DeepSeek-v4.1-flash, compared to GLM-5.3-flash via ZAI's Coding Plan? Because that's what I use; and often hit the "wait". I wouldn't mind trying a new model subscription or even API access which hits around glm-5.3-flash level weight class (which seem to be enough for me; with quite some human suprvision and nudging) but gives muuuuuuch moooore tokens for the same price.

(And what are the preferred providers?)
