Start building free
gpt-4 (gpt-4) is a large-scale generative AI model developed by OpenAI as part of the GPT‑4 family of models. It is positioned as a general-purpose, higher-tier model compared with earlier GPT‑3.x systems, offering stronger reasoning, coding, and language understanding capabilities across many domains. The model is typically used via API and in products like ChatGPT for tasks such as advanced conversation, code generation, content creation, and analysis. Compared with lighter, cheaper models, gpt‑4 generally trades higher cost and latency for better reliability, depth of reasoning, and performance on complex tasks.

Every request must include an Authorization: Bearer <TOKEN> header. Generate a token from your account's API Keys page — its access to models is set automatically from your active plans and redeemed codes, and you can set its rate limit and IP restrictions.
| 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. |
