Two routes. One API. You choose the border.
A sovereign route served only inside the Kingdom, and an international route for frontier models. Each key belongs to one of them, and a sovereign request never crosses over.
New accounts get $2.00 of free credit, valid for 30 days. No card.
Pick by where the data may go
Both speak the same API, bill from the same credit and live in the same console. What differs is where a request may be answered.
Sovereign route
For data that must stay in the Kingdom: government, health, finance, anything regulated.
- Sigmix GPUs in the Kingdom, and in-Kingdom partners
- Arabic models such as ALLaM, and open models such as Qwen
- No fallback abroad — a request that cannot be served here fails
/ksa-sovereign-route-only/v1International route
For the frontier models that cannot run inside the Kingdom, when the data is allowed to travel.
- Frontier models from named providers
- Sigmix GPUs abroad for open models at scale
- Never mixed with sovereign traffic
/international-route-only/v1Enforced three times, not promised once
A residency claim is only as strong as the weakest place it could fail. So it is enforced in three independent places.
The key
Each key is minted for one route. A sovereign key presented on the international path is refused before anything else happens.
The path
Each route has its own base path and its own handler. Nothing in a request can choose the other one.
The database
A sovereign model cannot be linked to an endpoint outside the Kingdom. The database refuses the row, whoever tries.
When every in-Kingdom endpoint for a model is down, the answer is an error — not a quiet detour through another country.
Text, speech and images
Five OpenAI-compatible endpoints on each route. The table is the live roster — models appear here when they are published.
| Endpoint | KSA only | Served abroad |
|---|---|---|
| Chat | 1 model | — |
| Embeddings | — | — |
| Text to speech | — | — |
| Speech to text | — | — |
| Image generation | — | — |
A dash means no model is published there yet, not that the endpoint is missing.
Prepaid, reserved, settled to the micro-dollar
Reserved first
Before a request reaches a model, the most it could cost is held from your credit. A request you cannot pay for is refused, not run.
Settled exactly
When it finishes you are charged what it used, from the model's own count, and the rest of the hold comes back.
Dollars or riyals
Metered in US dollars and shown in either at the fixed 3.75 peg. When you top up, the tax invoice is in riyals with VAT.
Point your client at the route
If your code already calls OpenAI, change the base URL and the key. That is the whole migration.
