DeepSeek v4 - Subjective vibes

I must say Iam kinda torn what to think about those models. At one hand they "ace" some questions on other sometime they behave genuinely weird. For example the big model appears to be "stubborn" like "3" era Claude used to be. It has some oppinion eg about historic figure and even if you present facts it will keep insisting on its version. The lite model confidently lied to me, but when found out it became honest and very friendly.
