Same code as the OpenAI SDK — change the base URL and key, pick a model id:
from openai import OpenAI
client = OpenAI(
base_url="https://api.airforce/v1",
api_key="YOUR_KEY",
)
resp = client.chat.completions.create(
model="glm-4",
messages=[{"role": "user", "content": "Hello!"}],
)
print(resp.choices[0].message.content)Frequently asked questions
- How do I use GLM models through Api.Airforce?
- Point any OpenAI-compatible client at https://api.airforce/v1 and set the model id (for example "glm-4"). Your existing OpenAI SDK works unchanged — you only swap the base URL and API key. The same key also speaks the Anthropic Messages API.
- Are any GLM models free?
- Yes — 1 of the 14 GLM models is on the free tier and callable at $0 (for example GLM 4.7 Flash). A free account needs no credit card; the remaining models are pay-as-you-go.
- How much do GLM models cost on Api.Airforce?
- Billing is pay-as-you-go per token, at rates that sit well below the official APIs. The exact per-model input and output prices are listed in the table above and update automatically as upstream prices change.
- Which GLM models are available?
- Currently 14 GLM models, including GLM 4, GLM 4 Airx, GLM 4 Flash. The catalog is refreshed as new models launch, so the list above is always current.
