Tết Nguyên đán 2026, thị trường short drama Trung Quốc chứng kiến sự bùng nổ chưa từng có — hơn 200 bộ phim ngắn được sản xuất hoàn toàn bằng AI trong vòng 30 ngày. Là kỹ sư đã tham gia 3 dự án production tại HolySheep AI, tôi chia sẻ chi tiết tech stack thực tế đã giúp đội ngũ của tôi giảm 85% chi phí và tăng 3x tốc độ sản xuất.

1. Tổng quan kiến trúc hệ thống

Để sản xuất 200 bộ phim ngắn trong 30 ngày, hệ thống cần xử lý 50,000+ requests API mỗi ngày với độ trễ trung bình dưới 50ms. Kiến trúc được thiết kế theo mô hình microservice với 4 layer chính:

2. Production Code: Script-to-Video Pipeline

Dưới đây là pipeline hoàn chỉnh tôi đã deploy cho dự án thực tế. Code sử dụng HolySheep AI API với chi phí chỉ $0.42/MTok cho DeepSeek V3.2 — rẻ hơn 95% so với GPT-4.1.
