### Attributes

<h4 id="atoti_ai_openai.ChatConfig.model">
  *model*
</h4>

The ID of the model to use, for example `"gpt-4o"`.

<h4 id="atoti_ai_openai.ChatConfig.temperature">
  *temperature*
</h4>

Controls randomness in responses from 0.0 (deterministic) to 2.0 (creative).

Not supported by reasoning models (e.g. o1, o3, gpt-5).

<h4 id="atoti_ai_openai.ChatConfig.top_p">
  *top\_p*
</h4>

Nucleus sampling parameter.

Controls diversity via cumulative probability.
Not supported by reasoning models (e.g. o1, o3, gpt-5).

<h4 id="atoti_ai_openai.ChatConfig.max_tokens">
  *max\_tokens*
</h4>

Maximum number of tokens to generate in the response.

For non-reasoning models.
Mutually exclusive with [`max_completion_tokens`](#atoti_ai_openai.ChatConfig.max_completion_tokens).

<h4 id="atoti_ai_openai.ChatConfig.max_completion_tokens">
  *max\_completion\_tokens*
</h4>

Maximum number of tokens to generate for reasoning models (e.g. o1, o3).

Mutually exclusive with [`max_tokens`](#atoti_ai_openai.ChatConfig.max_tokens).

<h4 id="atoti_ai_openai.ChatConfig.seed">
  *seed*
</h4>

Seed for deterministic sampling (Beta).

<h4 id="atoti_ai_openai.ChatConfig.tool_choice">
  *tool\_choice*
</h4>

Tool/function calling behavior (`"none"`, `"auto"`, or a specific function name).

<h4 id="atoti_ai_openai.ChatConfig.parallel_tool_calls">
  *parallel\_tool\_calls*
</h4>

Enable parallel function calling during tool use.

<h4 id="atoti_ai_openai.ChatConfig.extra_body">
  *extra\_body*
</h4>

Additional parameters for OpenAI-compatible servers.
