Huong Dan Tich Hop HolySheep: Code Mau

Sau day la huong dan tich hop HolySheep voi cac ngon ngu pho bien nhat. Tat ca deu su dung base_url la https://api.holysheep.ai/v1.

Python - OpenAI Compatible

from openai import OpenAI

Vi Sao Chon HolySheep?

1. Toc Do Phan Ung That Su

Trong khi nhieu API proxy co do tre 200-500ms, HolySheep duy tri latency <50ms nho he thong cau hinh toi uu va duong truyen thang toc.

2. Thanh Toan Linh Hoat

3. Tinh Tuong Thich

HolySheep su dung OpenAI-compatible API, co nghia la ban chi can doi base_url la tat ca code cu deu hoat dong ngay. Khong can thay doi logic, khong can hoc API moi.

4. Ho Tro Nhieu Model
