Keep everyday requests on DOS. Use eligible paid routes for complex work, with visibility into the model serving each request.
Complexity Check
DOS classifies the request as Simple, Medium, or Complex.
Simple • Medium • Complex
Route Decision
Simple and Medium use DOS.AI. Complex can use an eligible route from the live catalog.
DOS.AI • Eligible Route
Provider Request
The gateway sends the request through the route resolved from the tier and current catalog configuration.
Catalog-driven
Visible Route
Response headers identify the requested and provider model so your application can inspect the route.

Can’t find what you’re looking for? Reach out to our support team at support@dos.ai.
What models does DOS support?
Browse the live model catalog for current models, capabilities, context limits, and prices. Availability can change as providers update their offerings.
How does pricing work?
We use pay-as-you-go pricing based on metered usage. There is no minimum commitment, and current rates are published by model.
Is there a free tier?
Yes. New users get $5 in free credits to explore the API before adding funds.
How fast is the inference?
Performance depends on the selected route, model, prompt, and load. Our public benchmark snapshot includes its workload and measured results.
Can Smart Router reduce my AI costs?
Smart Router classifies request complexity: simple and medium requests use DOS; complex requests can use an eligible paid route. Savings depend on your workload, token usage, and comparison model. There is no fixed savings percentage.
Is my data secure?
DOS uses TLS in transit, scoped API access, and managed secret references. Requests may be processed by the model provider selected for the route.
Do you offer enterprise plans?
