How to Switch Between Models
Since both GPT-5.4 and DeepSeek R1 are available through AI API Hub with OpenAI-compatible API format, switching between them requires only changing the model name parameter. Your existing SDK code works without modification.
from openai import OpenAI client = OpenAI(api_key="YOUR_KEY", base_url="https://api.apiyihe.org/v1") # Before: response = client.chat.completions.create(model="gpt-5.4", messages=[...]) # After: response = client.chat.completions.create(model="deepseek-r1", messages=[...])
import OpenAI from "openai";
const client = new OpenAI({apiKey: process.env.KEY, baseURL: "https://api.apiyihe.org/v1"});
// Before: model: "gpt-5.4"
// After: model: "deepseek-r1"curl https://api.apiyihe.org/v1/chat/completions \
-H "Authorization: Bearer YOUR_KEY" \
-d '{"model": "deepseek-r1", "messages": [{"role":"user","content":"Hello"}]}'💡 AI API Hub supports both models through one API key. No separate accounts needed. Pay with USDT/USDC for all models.
Frequently Asked Questions
