Pareto Inference

Data handling can vary by model and deployment. The privacy badge above shows the more conservative of the provider-wide fallback and the policies for routes on this page; each model page shows the policy for that specific route.

Pareto Inference may log API request content for operational purposes and ordinarily retains captured API content for up to 14 days. Pareto stated during onboarding that inference content is not used for training or evaluation. This route is not zero data retention.

Models served by Pareto Inference

Model	Context	Input /M	Output /M	Cache read /M	Latency	Throughput

Prices are per million tokens. Selectable routes include the applicable provider-selection markup; fixed routes show the standard model price. Availability and pricing refresh continuously; each model page shows the live provider comparison.

Using Pareto Inference via the API

For models with provider selection, append :pareto to the model ID, set "provider": "pareto" in the request body, or send an X-Provider: pareto header. Explicit provider selection adds a route-specific markup over that provider's base price; the prices in the table above already include it. Models without provider selection use the displayed model ID without a provider suffix or selection surcharge.
