Use this model

The SDK examples assume you have created a server-side client.

const completion = await client.chat.completions.create({
  model: "codestral-2508",
  messages: [{ role: "user", content: "Explain edge caching in one paragraph." }],
});

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

completion = client.chat.completions.create(
    model="codestral-2508",
    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":"codestral-2508","messages":[{"role":"user","content":"Explain edge caching in one paragraph."}]}'

Supported parameters

messages, temperature, max_completion_tokens, top_p, stop, frequency_penalty, presence_penalty, seed, stream, user, routing, tools, tool_choice, response_format Send only parameters from this list. routing.require_parameters (default true) skips any provider rail that cannot honor every requested parameter, so unsupported parameters reduce the rails eligible to serve the request.

Routing & fallbacks

Pin codestral-2508 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 codestral-2508 is the explicit fallback; ninja/auto acts as the router only when it is the first entry.

{
  "models": [
    "ninja/auto",
    "codestral-2508"
  ],
  "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.
