Pricing	usage	free
Strengths	+ Deepest reasoning of the Claude family + Best for ambiguous, planning-heavy tasks	+ 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	− Highest cost tier — not viable as default model − Higher latency than Sonnet / Haiku	− Branded as a preview release on deepseek.com as of June 2026 − V4-Pro's scale makes self-hosting impractical without large GPU clusters
