Quickstart

Call cogview-4 with a POST to /v1/images/generations on https://api.oxyy.ai, using your Oxyy API key from the OXYY_API_KEY environment variable. The same key works for every model in the catalog.

import os
from openai import OpenAI

client = OpenAI(
    base_url="https://api.oxyy.ai/v1",
    api_key=os.environ["OXYY_API_KEY"],
)

response = client.images.generate(
    model="cogview-4",
    prompt="A lighthouse on a cliff at sunset, watercolor",
    n=1,
    size="1024x1024",
)
print(response.data[0].url)

Availability

The share of requests to this model that completed successfully over the last 30 days. Requests the caller cancelled, and requests still in flight, are not counted. When an upstream provider errors, the gateway retries against another provider serving the same model, so a single provider incident does not necessarily show up here.
