DeepSeek V4-Pro: 75% Price Cut Becomes Permanent
On May 22, 2026, DeepSeek made its 75% promotional discount on V4-Pro permanent rather than letting it expire May 31. New permanent rates: $0.435/M input, $0.87/M output, $0.003625/M cache hit. That puts V4-Pro output roughly 34x cheaper than GPT-5.5 and 17x cheaper than Claude Opus 4.7, while landing within 3-7 points on coding and reasoning benchmarks. The underrated detail is the cache-hit price, which can cut input cost ~88% for agents with stable prefixes. Teams should re-run their build math and route the easy majority of traffic to V4-Pro.
