Crusoe¶

Crusoe provides Managed Inference, an OpenAI-compatible API for open-weight models, powered by vLLM. Because the service speaks the OpenAI API, code written against a self-hosted vLLM server works against Crusoe endpoints without changes.

Prerequisites¶

• A Crusoe account
• An Inference API key, created in the Crusoe Console under Security > Inference API Key

Set the key as an environment variable:

export CRUSOE_API_KEY="your-api-key"

Using the OpenAI SDK¶

Point the OpenAI client at the Crusoe endpoint:

import os

from openai import OpenAI

client = OpenAI(
    base_url="https://api.inference.crusoecloud.com/v1",
    api_key=os.environ["CRUSOE_API_KEY"],
)

response = client.chat.completions.create(
    model="zai/GLM-5.2",
    messages=[{"role": "user", "content": "Hello, how are you?"}],
)

print(response.choices[0].message.content)

Verifying with curl¶

curl https://api.inference.crusoecloud.com/v1/chat/completions \
    -H "Authorization: Bearer $CRUSOE_API_KEY" \
    -H "Content-Type: application/json" \
    -d '{
        "model": "zai/GLM-5.2",
        "messages": [
            {"role": "user", "content": "Hello, how are you?"}
        ],
        "max_tokens": 50
    }'

Available models¶

List the current model catalog:

curl https://api.inference.crusoecloud.com/v1/models \
    -H "Authorization: Bearer $CRUSOE_API_KEY"
