GPT-5.6 API
Get started with GPT-5.6 API through InferGate: choose an exact model ID, configure your SDK and verify prepaid account access.
Integrate GPT-5.6 API into an existing server application through https://api.useinfergate.com/v1. Choose sol or terra explicitly; a family name is not a request identifier.
Choose the published identifier
From account to first response
- Create an account or sign in to your existing account.
- Check wallet balance and create a server-side API key.
- List the models your key can access, then send one small request.
- Inspect the returned model, completion status and usage before increasing traffic.
SDK integration path
Follow the Python guide or Node.js guide. Existing clients can use the custom base URL checklist. For incremental output, use the streaming guide.
Prepaid usage and costs
API usage consumes available account credit. Review current input and output rates in application pricing before running a workload. This page does not promise free requests or a fixed discount. See how prepaid pricing works and compare actual usage logs after a small test.

This page covers account-to-request setup for GPT-5.6. Use the model reference for exact identifiers and response checks.
| Your starting point | Recommended next step | Acceptance check |
|---|---|---|
| New integration | Create an account and list accessible models | The desired exact ID is returned |
| Existing OpenAI SDK client | Set InferGate base URL and key | A small Responses request completes |
| Interactive application | Add streaming event handling | Deltas arrive and completion is recorded |
| Production workload | Review rates and run a limited evaluation | Usage logs match the completed responses |
Runnable integration example
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-sol","input":"Return a short release note for an API client update.","max_output_tokens":256}'Frequently asked questions
How do I get GPT-5.6 API access?
Create an InferGate account, check the wallet and model permissions, and create a server-side API key. Use the authenticated catalog before sending a small test request.
Which GPT-5.6 model IDs are available?
gpt-5.6-sol and gpt-5.6-terra. Availability is checked per account; the family name is not a generic routing alias.
Is there a fixed price or guaranteed free allocation?
This page makes no fixed-price or free-credit promise. Review current application pricing, account balance and any applicable credit conditions before running requests.
Can I keep my existing SDK?
The examples use the OpenAI SDK with a custom base URL and an InferGate key. Validate the endpoint and parameters your application uses instead of assuming complete feature parity.
