Discover the models currently available to your key.

Errors

Error responses follow the OpenAI shape; error.type identifies the origin.

Compatibility

Python

from openai import OpenAI

client = OpenAI(
    base_url="https://api.aitree.ai/v1",
    api_key="AITREE_API_KEY",
)

resp = client.chat.completions.create(
    model="deepseek-v4-flash-0731",
    messages=[{"role": "user", "content": "Hello"}],
)
print(resp.choices[0].message.content)
