Strengths	+ Purpose-built for RAG with citation grounding + Multilingual + Enterprise deploy options	+ MIT-licensed open weights for both Pro and Flash variants + 1M-token context window + Selectable reasoning effort modes (non-think plus two thinking modes) + Sparse MoE design keeps activated parameters low relative to total size
Tradeoffs	− Smaller ecosystem than Claude/OpenAI	− Branded as a preview release on deepseek.com as of June 2026 − V4-Pro's scale makes self-hosting impractical without large GPU clusters
