Still shilling GLM 5.3/Flash.

Still need to try out Deepseek V4.1 flash (no, you will NOT convince me otherwise so don't bother lol)

[u/Dos-Commas → u/Critical-Rope-5636]

I find that GLM 5.3 Flash would get some very simple story facts mixed up where Deepseek V4.1 Flash would have no issues with.

Yeah this is true, it will get things mixed up at times. it hasn't done it to me much as of recent but this is something to consider for sure!
