英文原文
Official pricing update
DeepSeek's pricing page has changed the V4-Pro story from a short promotion into an official post-promotion price reset. The current English and Chinese pages both say the V4-Pro API price will be officially adjusted to 1/4 of the original price after the 75% discount window ends.
The exact cutoff is 2026-05-31 15:59 UTC, or 2026-05-31 23:59 Beijing time.
What is confirmed now
- DeepSeek V4 Pro cache-hit input: $0.003625 / 1M tokens
- DeepSeek V4 Pro cache-miss input: $0.435 / 1M tokens
- DeepSeek V4 Pro output: $0.87 / 1M tokens
- DeepSeek V4 Flash remains $0.0028 cache-hit input, $0.14 cache-miss input, and $0.28 output per 1M tokens
What this does not mean
This is not a promise of permanent stock, unlimited access, or a forever price guarantee. DeepSeek's own pricing page still says product prices may vary and that DeepSeek reserves the right to adjust them. The accurate buyer-facing wording is: the 75% V4-Pro discount becomes the official quarter-price baseline after May 31, subject to DeepSeek's future pricing changes.
Site handling
For this hub, the update changes content and comparison copy, but it does not create a new purchasable product. The pricing page should continue to show only stocked one-off Coding Plans, and benchmark or arena support still must not be treated as sellable inventory.
