Use this model

Set up your SDK client, then run:

const completion = await client.chat.completions.create({
  model: "qwen-2.5-72b",
  messages: [{ role: "user", content: "Explain edge caching in one paragraph." }],
});

console.log(completion.choices[0].message.content);

completion = client.chat.completions.create(
    model="qwen-2.5-72b",
    messages=[{"role": "user", "content": "Explain edge caching in one paragraph."}],
)

print(completion["choices"][0]["message"]["content"])

curl https://www.ninjachat.ai/api/v1/chat/completions \
  -H "Authorization: Bearer $NINJACHAT_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model":"qwen-2.5-72b","messages":[{"role":"user","content":"Explain edge caching in one paragraph."}]}'

Send only parameters from this list. routing.require_parameters (default true) skips any provider rail that cannot honor every requested parameter, so requests keep the behavior you asked for.

Routing & fallbacks

Pin qwen-2.5-72b with model when you want this model’s behavior, or list it in an ordered models array. With ninja/auto first, the router’s top pick runs first and qwen-2.5-72b is the explicit fallback; ninja/auto acts as the router only when it is the first entry.

{
  "models": [
    "ninja/auto",
    "qwen-2.5-72b"
  ],
  "messages": [
    {
      "role": "user",
      "content": "Explain edge caching in one paragraph."
    }
  ],
  "routing": {
    "allow_fallbacks": true
  }
}

You are billed at the resolved model’s token rates, and only for the successful execution.
