gpt-5.4-nano is an OpenAI model name that follows the company’s established convention for small, fast, and low‑cost "nano"‑tier models, designed primarily for lightweight tasks and high‑throughput deployment. While detailed public documentation on this exact 5.4 variant is not widely available, models in the nano family are generally much smaller and cheaper to run than flagship GPT versions, trading some depth of reasoning and creativity for speed and efficiency. They are typically suited for things like simple chatbots, UI helpers, basic classification, and on‑demand text utilities where latency and cost are more important than top‑end capabilities.

| Parameter | Type | Description |
|---|---|---|
model | string, required | This model's ID, exactly as shown above. |
messages | array, required | Conversation history as role/content objects (system, user, assistant). |
temperature | number, optional | Sampling randomness, typically 0–2. |
max_tokens | integer, optional | Upper limit on tokens generated in the reply. |
top_p | number, optional | Nucleus-sampling threshold, as an alternative to temperature. |
stream | boolean, ignored | Responses are always returned in full so the exact cost can be billed; streaming is not available. |
