Required Fields​

model​

string - ID of the model to use.

model="anthropic/claude-sonnet-4-6"
model="google/gemini-2.5-flash"

messages​

array - A list of messages comprising the conversation so far.

messages=[
    {"role": "system", "content": "You are a helpful assistant."},
    {"role": "user", "content": "Hello!"}
]

Properties of messages​

  • role: string - The role of the message's author. Roles can be: system, user, assistant, function or tool.
  • content: string or list[dict] or null - The contents of the message.
  • name: string (optional) - The name of the author of the message.
  • tool_call_id: str (optional) - Tool call that this message is responding to.

Optional Fields​

temperature​

number or null (optional) - The sampling temperature to be used, between 0 and 2.

response = client.chat.completions.create(
    model="openai/gpt-4o",
    messages=[{"role": "user", "content": "Hello"}],
    temperature=0.7
)

max_tokens​

integer (optional) - The maximum number of tokens to generate in the chat completion.

response = client.chat.completions.create(
    model="openai/gpt-4o",
    messages=[{"role": "user", "content": "Hello"}],
    max_tokens=100
)

max_completion_tokens​

integer (optional) - An upper bound for the number of tokens that can be generated for a completion, including visible output tokens and reasoning tokens.

top_p​

number or null (optional) - An alternative to sampling with temperature. It instructs the model to consider the results of the tokens with top_p probability.

n​

integer or null (optional) - The number of chat completion choices to generate for each input message.

stream​

boolean or null (optional) - If set to true, it sends partial message deltas.

response = client.chat.completions.create(
    model="openai/gpt-4o",
    messages=[{"role": "user", "content": "Hello"}],
    stream=True
)

for chunk in response:
    print(chunk.choices[0].delta.content or "", end="")

stream_options​

dict or null (optional) - Options for streaming response. Only set this when you set stream: true.

  • include_usage boolean (optional) - If set, an additional chunk will be streamed with token usage statistics.

stop​

string/array/null (optional) - Up to 4 sequences where the API will stop generating further tokens.

presence_penalty​

number or null (optional) - Penalizes new tokens based on their existence in the text so far.

frequency_penalty​

number or null (optional) - Penalizes new tokens based on their frequency in the text so far.

response_format​

object (optional) - An object specifying the format that the model must output.

response = client.chat.completions.create(
    model="openai/gpt-4o",
    messages=[
        {"role": "system", "content": "Output JSON."},
        {"role": "user", "content": "List 3 colors"}
    ],
    response_format={"type": "json_object"}
)

seed​

integer or null (optional) - If specified, the system will make a best effort to sample deterministically.

tools​

array (optional) - A list of tools the model may call.

tools = [
    {
        "type": "function",
        "function": {
            "name": "get_weather",
            "description": "Get the weather in a location",
            "parameters": {
                "type": "object",
                "properties": {
                    "location": {"type": "string"}
                },
                "required": ["location"]
            }
        }
    }

  • {"type": "function", "function": {"name": "my_function"}} - Forces the model to call that function

parallel_tool_calls​

boolean (optional) - Whether to enable parallel function calling during tool use.

logit_bias​

map (optional) - Used to modify the probability of specific tokens appearing in the completion.
