Описание и применение

Снижение стоимости инфраструктуры для приложений с компьютерным зрением до <$15/год, используя API DeepSeek V4.1 Flash и дешевые CPU‑серверы.

Задача

High infrastructure costs for vision AI apps due to expensive GPU instances.

Результат

Reduced vision AI infrastructure cost to <$15/year while maintaining high accuracy and fast inference.

Рабочий процесс

• 1. Set up a Node.js Express backend for authentication and image upload.
• 2. Receive image, encode to base64 or signed URL.
• 3. Call DeepSeek V4.1 Flash API with image payload.
• 4. Return JSON response to frontend.
• 5. Host React frontend on Vercel for free.

Доказательства

DeepSeek V4.1 Flash excels at extracting structured JSON data from messy receipts, analyzing UI screenshots for accessibility issues, and describing complex architectural diagrams.
