Why DeepSais

Serious AI, serious savings

We make bleeding-edge models accessible and affordable. No hoops, no hidden fees.

💰

95% Cheaper Than GPT-5.5

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.

🔄

Drop-In OpenAI Replacement

Change one base URL and your entire codebase works. SDKs, streaming, function calling, JSON mode — all fully compatible. Zero refactoring required.

US Edge Network

Servers deployed in Virginia. Sub-100ms latency for North American users. No cross-Pacific lag, no unreliable routing. Your requests stay fast.

💳

Credit Card Checkout

Pay with Visa, Mastercard, or any major card via Stripe. No crypto wallets, no weird payment gateways. Just the checkout flow you already trust.

Pricing

Transparent, pay-as-you-go

All prices per 1 million tokens. No monthly minimum. No surprises.
