Openai: gpt-5.5
gpt-5.5
Start building free
gpt-5.5 (gpt-5.5) is described as a hypothetical mid-cycle iteration in OpenAI’s GPT-5 family, following the company’s common pattern of releasing “point” upgrades (like GPT-3.5) that refine capability, latency, and cost without being a full new generation. Such a model would be expected to provide stronger reasoning, more reliable tool use, and broader multimodal support than earlier GPT‑4/4.1–class models, while targeting a balance between high-end performance and practical deployability for products. In industry terms, it would likely sit in a premium but versatile tier: suitable for complex coding and analysis, agentic workflows, and enterprise assistants, yet optimized enough for large-scale, real-time applications. As of now, however, OpenAI has not publicly released an official model under the exact name “gpt-5.5,” so any details remain inferred from established naming conventions and prior generations.

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. |
