description: "Complete DeepSeek API pricing for July 2026. V4 Flash $0.14/$0.28, V4 Pro $0.42/$0.84. Cost breakdown with real usage scenarios."

DeepSeek offers two flagship models in 2026: V4 Flash (speed and cost) and V4 Pro (quality). Both are available through AIWave at a small markup over direct DeepSeek pricing, with the benefit of a single API key and PayPal payments.

Official vs AIWave Pricing

DeepSeek DirectAIWaveMarkup
V4 Flash Input$0.14$0.140%
V4 Flash Output$0.28$0.280%
V4 Pro Input$0.435$0.42-3%
V4 Pro Output$0.87$0.84-3%

DeepSeek direct prices from api-docs.deepseek.com. AIWave prices from aiwave.live/pricing.

AIWave is actually slightly cheaper than going direct for V4 Pro. This is possible because AIWave negotiates volume pricing and the small overhead from their aggregation layer is absorbed.

DeepSeek's 1M context window is 5-8x larger than most competitors. For codebase analysis and long documents, this means fewer API calls to chunk and reassemble content.

Cached Input Pricing

DeepSeek offers cached input discounts (prefix matching). When your request shares a prefix with a recent request, input tokens are cheaper:

V4 Pro$0.435/1M$0.0036/1M (99% off)

Cached input works automatically — no code changes needed. Repeated prompts or system instructions trigger the discount.
