GPT-5.6 Luna
Review GPT-5.6 Luna model IDs, endpoint, request parameters, and response examples for HopsAPI.
GPT-5.6 Luna is a chat model in the HopsAPI catalog. This page documents only gateway-verified protocols, endpoints, and model IDs; context length, vision, tools, reasoning, and JSON capabilities depend on the current upstream and live response.
Model information
| Item | Value |
|---|---|
| Protocol | OpenAI Chat Completions; also OpenAI Responses when the model list includes responses_endpoint |
| Endpoint | POST /v1/chat/completions; optional POST /v1/responses |
| Availability | Use the current API key's GET /v1/models response |
| Pricing | Use the console pricing page and account coefficient |
Model IDs
| Model ID | Notes |
|---|---|
gpt-5.6-luna | Use this ID when returned by the current API key's model list |
Do not assume that the model is enabled for your account from this page alone. Before calling it,
query GET /v1/models and use the returned model ID, endpoint, and optional
responses_endpoint exactly.
Core request parameters
| Parameter | Required | Description |
|---|---|---|
model | Yes | Use an ID above that is returned by the model list |
messages | Yes | Message array in the protocol's native format |
max_tokens | No | Limits model output length |
