DeepSeek will keep its 75% discount on the V4-Pro API after the promo ends May 31, locking permanent prices at $0.435 per million input tokens and $0.87 output — a quarter of the original sticker rate.

## What it is

DeepSeek-V4-Pro is the company's flagship API model. A 75% promotional discount on its API was set to expire on May 31, 2026. DeepSeek now says the cut is permanent: once the promo window closes, the standing price stays at one-quarter of the original sticker rate.

## How it works

Per DeepSeek's pricing docs, cache-miss input drops to $0.435 per million tokens and output to $0.87, both a quarter of the original $1.74 and $3.48 list prices. Cache-hit input falls to $0.003625 per million, roughly a 90% reduction on cached reads across the API line.

## Why it matters

For agentic and long-context workloads that re-read large prompts repeatedly, the cache-hit price reshapes the cost math. Teams can run a low-cost, OpenAI-compatible API on open harnesses without contract lock-in.

## Who it's for

API developers, agent builders, cost-sensitive teams
