DeepSeek V4

DeepSeek V4 is a documentation-focused repository that explains how to guide DeepSeek V4 roleplay behavior through special first-message instructions. Rather than providing a conventional application, it acts as a practical prompt-control reference for users who want to influence the model’s thinking-mode style during roleplay sessions. It describes three operating styles: default behavior, role immersion, and pure analysis. Role immersion encourages character-like internal framing, while pure analysis pushes the model toward structured scene planning without dramatic inner monologue. The guide explains how to apply the instructions in the web client and how developers can append the markers programmatically when calling supported DeepSeek V4 API models. It also notes that the behavior is probabilistic, meaning the instructions can improve consistency but cannot guarantee perfect activation every time.
