Using third-party SDKs

Point the OpenAI SDK at https://infapi.cc/v1 with $INFAPI_API_KEY. The HTTP samples above are the request shape this gateway accepts.

from openai import OpenAI

client = OpenAI(
    base_url="https://infapi.cc/v1",
    api_key="$INFAPI_API_KEY",
)

response = client.chat.completions.create(
    model="meta/muse-spark-1.2",
    messages=[{"role": "user", "content": "Introduce yourself in three sentences."}],
    temperature=0.7,
    max_tokens=512,
)
print(response.choices[0].message.content)

import OpenAI from "openai";

const client = new OpenAI({
  baseURL: "https://infapi.cc/v1",
  apiKey: "$INFAPI_API_KEY",
});

const response = await client.chat.completions.create({
  "model": "meta/muse-spark-1.2",
  "messages": [
    {
      "role": "user",
      "content": "Introduce yourself in three sentences."
    }
  ],
  "temperature": 0.7
});

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

Supported parameters

• include_reasoning

  Include reasoning

  Include a reasoning summary in the response.

• max_tokens

  Max tokens

  Upper bound on generated tokens. Output stops at the limit.

• reasoning

  Reasoning

  Enable or configure reasoning. The fields differ by model.

• reasoning_effort

  Reasoning effort

  How much compute to spend reasoning. Often low, medium, or high.

• repetition_penalty

  Repetition penalty

  Penalizes text that already appeared. Common on open models.

• response_format

  Response format

  For example json_object or json_schema, to constrain the shape.

• structured_outputs

  Structured outputs

  Generate a parseable structure that follows a JSON Schema.

• temperature

  Temperature

  Sampling temperature. Lower is steadier, higher is more varied. Often 0 to 2.

• tool_choice

  Tool choice

  Whether to call a tool: auto, none, or a named function.

• tools

  Tools

  Function definitions the model may call via tool_calls.

• top_k

  Top-K

  Sample only from the K most likely tokens.

• top_p

  Top-p

  Sample only from tokens whose cumulative probability reaches top_p.
