DeepSeek V4 Review: A Weapon to Rent, Not a Vendor to Marry

DeepSeek V4 is cheap and genuinely capable: V4-Pro runs about 29x cheaper than Claude Opus 4.8 on output. The price is the honest part. Hosted data sits in the PRC, the policy warns against sensitive data, and FSR’s tests show it breaking on China’s political red lines. Rent it; do not marry it.
