Difference between GGMLFType

[Starlento]

For ggml, there are many types. Just like Q{i} means to {i} precision.
I would like to know the meaning of the last _0, _1, _K_M and so on.
It would be great to share some insights and experience as well.

class GGMLFType(IntEnum):
    ALL_F32              = 0
    MOSTLY_F16           = 1
    MOSTLY_Q4_0          = 2
    MOSTLY_Q4_1          = 3
    MOSTLY_Q4_1_SOME_F16 = 4
    MOSTLY_Q8_0          = 7
    MOSTLY_Q5_0          = 8
    MOSTLY_Q5_1          = 9
    MOSTLY_Q2_K          = 10
    MOSTLY_Q3_K_S        = 11
    MOSTLY_Q3_K_M        = 12
    MOSTLY_Q3_K_L        = 13
    MOSTLY_Q4_K_S        = 14
    MOSTLY_Q4_K_M        = 15
    MOSTLY_Q5_K_S        = 16
    MOSTLY_Q5_K_M        = 17
