DeepSeek V4 Flash and V4 Pro, delivered through one OpenAI-compatible endpoint. Start building in 30 seconds. Pay with a credit card. No friction, no surprises.
We make bleeding-edge models accessible and affordable. No hoops, no hidden fees.
V4 Flash input costs $0.30 per million tokens. GPT-5.5 costs $5.00. That's not a typo — it's 16x less on input and 50x less on output.
Change one base URL and your entire codebase works. SDKs, streaming, function calling, JSON mode — all fully compatible. Zero refactoring required.
Servers deployed in Virginia. Sub-100ms latency for North American users. No cross-Pacific lag, no unreliable routing. Your requests stay fast.
Pay with Visa, Mastercard, or any major card via Stripe. No crypto wallets, no weird payment gateways. Just the checkout flow you already trust.
All prices per 1 million tokens. No monthly minimum. No surprises.

Drop-in compatible with the OpenAI SDK. Change one URL and you're done.
curl https://api.deepsais.cc/v1/chat/completions \ -H "Content-Type: application/json" \ -H "Authorization: Bearer sk-xxxxxxxx" \ -d '{ "model": "deepseek-v4-flash", "messages": [{"role": "user", "content": "Hello!"}] }'
# pip install openai from openai import OpenAI client = OpenAI( api_key="sk-xxxxxxxx", base_url="https://api.deepsais.cc/v1" ) response = client.chat.completions.create( model="deepseek-v4-flash", messages=[{"role": "user", "content": "Hello!"}] ) print(response.choices[0].message.content)
// npm install openai import OpenAI from 'openai'; const client = new OpenAI({ apiKey: 'sk-xxxxxxxx', baseURL: 'https://api.deepsais.cc/v1' }); const response = await client.chat.completions.create({ model: 'deepseek-v4-flash', messages: [{ role: 'user', content: 'Hello!' }] }); console.log(response.choices[0].message.content);
Both models support 1M context, 384K max output, streaming
(stream: true),
function calling, and JSON mode. V4 Flash is optimized for speed and cost;
V4 Pro for complex reasoning and agent workflows.
Both plans include full API access and usage dashboard. No hidden fees, cancel anytime.
