5 Reasons to Use Yingsuan AI for Your Next AI Project — 100 Free Calls to Start

#ai #api #llm #deepseek

Choosing an LLM API provider is not just about model quality anymore. It is about how fast you can prototype, how little friction your team faces, and how easy it is to switch models when a better one ships. Yingsuan AI is an OpenAI-compatible gateway built for exactly that. Here are five reasons it should be on your shortlist.

1. Start free with 3 permanently free models

You do not need a credit card to test the gateway. Every new key comes with 100 trial calls and access to 3 permanently free models:

glm-4-flash — fast general-purpose chat
glm-4.7-flash — lightweight tasks
qwen2.5-7b — solid coding and reasoning baseline

That is enough to build a working prototype, run integration tests, or let a small team evaluate the service before spending anything.

2. One key, multiple top Chinese LLMs

Instead of signing up for DeepSeek, Zhipu AI, and Alibaba Cloud separately, you get one API key that routes to all of them:

DeepSeek: deepseek-chat, deepseek-reasoner
GLM: glm-4-flash, glm-4-air, glm-4-plus
Qwen: qwen2.5-7b, qwen2.5-72b, deepseek-v3

One endpoint, one secrets manager entry, one retry policy. Your codebase stays clean even as your model stack grows.

3. OpenAI-compatible — switch with two lines of code

The gateway speaks the same /v1/chat/completions and /v1/models endpoints as OpenAI. If you already use the OpenAI SDK, you only change base_url and api_key:

from openai import OpenAI

client = OpenAI(
    base_url="https://yingsuan.top/v1",
    api_key="YOUR_YINGSUAN_API_KEY"
)

response = client.chat.completions.create(
    model="deepseek-chat",
    messages=[
        {"role": "system", "content": "You are a helpful coding assistant."},
        {"role": "user", "content": "Write a Python function that reverses a string."}
    ]
)
print(response.choices[0].message.content)

import OpenAI from "openai";

const client = new OpenAI({
  baseURL: "https://yingsuan.top/v1",
  apiKey: "YOUR_YINGSUAN_API_KEY"
});

const response = await client.chat.completions.create({
  model: "qwen2.5-72b",
  messages: [
    { role: "system", content: "You are a helpful coding assistant." },
    { role: "user", content: "Write a JavaScript function that reverses a string." }
  ]
});

console.log(response.choices[0].message.content);

That same pattern works in any language with an OpenAI client.

4. Built for developers who hate credit-card friction

If you are in Southeast Asia, Africa, or anywhere Stripe coverage is spotty, getting API credits can be harder than writing the code. Yingsuan AI accepts Wise bank transfer for paid tiers and lets you start without a card. The pricing is straightforward, and you only move to a paid tier once you have burned through the free allocation.

5. Low latency where it matters

The gateway is hosted from a China-based infrastructure hub with routing tuned for South and Southeast Asia. For teams building AI apps targeting users in those regions, that means lower round-trip times and a more responsive product without provisioning GPU clusters yourself.

Try it now

Get your free API key with 100 trial calls at yingsuan.top/api.html. No credit card required. If you are building a multi-model product and want to stop managing provider-specific clients, this is the fastest way to start.
