All models share one OpenAI-compatible endpoint. To switch models, change the model field. One key accesses every model.

# pip install openai
from openai import OpenAI

client = OpenAI(
    base_url="https://api.yomiapi.com/v1",
    api_key="sk-your-yomi-key",
)

resp = client.chat.completions.create(
    model="glm-5.3",
    messages=[{"role": "user", "content": "Hello"}],
)
print(resp.choices[0].message.content)

curl https://api.yomiapi.com/v1/chat/completions \
  -H "Authorization: Bearer sk-your-yomi-key" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "glm-5.3",
    "messages": [{"role": "user", "content": "Hello"}]
  }'
