Platform Intro

Unisound Maas Platform (maas.unisound.com) provides simple, flexible, and efficient large model APIs so developers can build intelligent applications faster and at lower cost.

Developer quickstart

Complete your first API call in minutes. Use any OpenAI-compatible SDK or client. Quickstart →

from openai import OpenAI

client = OpenAI(
    api_key="YOUR_API_KEY",
    base_url="https://maas-api.unisound.com/v1",
)

completion = client.chat.completions.create(
    model="u2-flash",
    messages=[{"role": "user", "content": "Hello"}],
)
print(completion.choices[0].message.content)

Models

Unisound provides ready-to-use model services—no self-hosting required. Call first-party U-Model series (including U2 Flash, Unisound U2, and more) as well as third-party models such as DeepSeek, Kimi, and GLM. All models share one API; switch by changing the model parameter. View all models →
