GPT-5.6-terra API model
Reference for gpt-5.6-terra on InferGate: exact request ID, response validation, streaming behavior and account access troubleshooting.
Use gpt-5.6-terra as the exact request identifier. This is one of two separately addressable GPT-5.6 variants; the suffix is part of the model ID. Non-streaming and streaming Responses requests passed the production catalog acceptance on September 11, 2026.
Request this model
curl --fail-with-body https://api.useinfergate.com/v1/responses \
-H "Authorization: Bearer $INFERGATE_API_KEY" \
-H "Content-Type: application/json" \
-d '{"model":"gpt-5.6-terra","input":"Reply with one sentence about API design.","max_output_tokens":256}'Choose deliberately
Compare sol and terra with your own evaluation set. No benchmark, context-window or speed advantage is asserted here. Confirm required parameters using a small representative request.
Check access before sending requests
Use your own InferGate key to request the live catalog. Account permissions, key restrictions and available balance still apply. A model listed here is not a guarantee of uninterrupted upstream service.
curl --fail-with-body https://api.useinfergate.com/v1/models \
-H "Authorization: Bearer $INFERGATE_API_KEY"Retired model requests return model_not_available. InferGate does not silently substitute another model. Keep keys on your server and out of browser bundles.

Frequently asked questions
Which identifier should I send for GPT-5.6 Terra?
Send gpt-5.6-terra exactly. Use the same API key to check GET /v1/models before requesting this model. Display labels and family names are not replacements for the request ID.
Why can a published model be unavailable to my key?
The website describes the public catalog. Your account group, API key model restrictions and balance can affect a specific request. Inspect the actual error and authenticated list before retrying.
Is sol faster or more accurate than terra?
No comparative speed or accuracy claim is established here. Compare both variants on the same representative prompts and current rates; model suffixes are not benchmark results.
How do I verify a streamed response?
Require the completion event and useful text. Preserve the request ID and actual model identity. A connection that ends before completion is not a successful result merely because HTTP status was 200.
