DeepSeek API Pricing 2026: V4 Flash, V4 Pro and Cost Breakdown

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 Direct	AIWave	Markup
V4 Flash Input	$0.14	$0.14	0%
V4 Flash Output	$0.28	$0.28	0%
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.

Context Window

Model	Context	Max Output	Cost per full context fill
V4 Flash	1M tokens	384K tokens	$0.31
V4 Pro	1M tokens	384K tokens	$0.93
GPT-4o (comparison)	128K tokens	16K tokens	$0.42

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.

Usage Scenarios

IDE Coding (Cursor, Continue)

200 calls/day, 4K input + 2K output, 22 days:

Model	Monthly
V4 Flash	$5
V4 Pro	$18
GPT-4o	$132
Claude Sonnet 4	$185

Chat Application (100 calls/day, 3K + 1.5K)

Model	Monthly
V4 Flash	$1.65
V4 Pro	$8
GPT-4o	$59

Cached Input Pricing

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

	Normal Input	Cached Input
V4 Flash	$0.14/1M	$0.0028/1M (95% off)
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.

Getting Started

AIWave provides DeepSeek V4 Flash as deepseek-chat and V4 Pro as deepseek-reasoner. Same OpenAI-compatible format, same response structure. The $1 free credit covers roughly 700 V4 Flash coding queries — enough for two weeks of daily use.
