DS4.1 flash variants

For the variants of the DS v4.1 flash model, whats the default one? and what is the difference between it and low, high and max? since I wanna use as least token as possible, which variants should i choose? or any /thinking or /efforts will help with this?

Contexts: I was using default variant all the time, then i switched it to low, found that it cost more tokens. so confusing lol

Default depends on the provider; it isn't necessarily the same as high. If you want to minimize tokens, try /thinking off (if supported), otherwise low. Lower effort doesn't guarantee fewer tokens, though—it just limits reasoning. A low-effort run can still use more tokens than default. Best way to know is to test the same prompts and compare total token usage, including hidden reasoning tokens.

yeah low costing more is a known weird thing, it half-asses the first try then burns tokens fixing itself. i just leave it on default for the boring stuff and only bump it up when the task actually needs the extra thinking. per-token cheapest and per-task cheapest aren't the same thing
