GPT-5.6 Sol
GPT-5.6 Sol language model.
One model, automatic routing. Use the model ID in every request.
Model pricing
No verified discountEach line has its own published sales rates. Automatic routing chooses the supply used; fallback can change the price charged. Use the same model ID in every request. No credit is reserved; admitted requests may overdraw the balance, blocking new requests.

These are published baseline text paths. Routing prefers an applicable native path and also considers cooldowns and each request’s features. This configuration does not show the path chosen for a request or current line health.

- Router request protocols
- Chat CompletionsResponsesMessages
- Routing configuration
- Configured routes: 2Configured upstream systems: 1No baseline HA
Capabilities and limits depend on the line and protocol path. Review the published configuration with each line’s price.
These are Router request protocols. Routing prefers an applicable native line; otherwise, compatible conversion may be used. Requests whose meaning cannot be preserved are rejected. This list does not establish native upstream support.
Baseline HA means plain-text JSON and streaming requests have cross-provider safe-fallback candidates on Chat, Responses, and Messages. It is not live health or an SLA, and does not cover extra capabilities such as tools or stop sequences.
