Quickstart

Call muse-spark-1.2-contributor with a POST to /v1/chat/completions 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.chat.completions.create(
    model="muse-spark-1.2-contributor",
    messages=[
        {"role": "user", "content": "Explain unified AI APIs in one sentence."},
    ],
)
print(response.choices[0].message.content)

Performance

Throughput is how fast the model writes (tokens per second — higher is better). Latency is total round-trip time (lower is better). TTFT is time-to-first-token — how long before you see anything appear (lower is better). Throughput and TTFT are measured on streaming requests, which are the only ones with a first-token moment to time.

Cache hit rate

30.27%
Share of input tokens served from the prompt cache over the window.

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.

Success rate (30 days)
58.30%
over 163 completed requests
Days with traffic
6
of the last 30 days

Days are UTC days. Days with no completed requests are omitted rather than drawn at 100% — no traffic is not evidence of availability.

Activity

Token volume and request traffic to this model over time. Daily totals, UTC.

Prompt25.9K
Reasoning33.3K
Completion (excl. reasoning)1.6K

Prompt tokens measure input size. Reasoning tokens show internal thinking before a response. They are part of the output, so the completion bars show the rest of it and each day’s bar is its total.
