FAQ

What model ID should I use for Inkling 2 Small?

Use thinkingmachines/inkling-2-small as the model field with the TrustedRouter OpenAI-compatible API. Credits routing and provider fallback happen behind that model ID.

No. Prompt and output content are intentionally excluded from the control plane and metadata systems. Optional content export requires explicit destination-level configuration.

Which providers serve Inkling 2 Small?

TrustedRouter currently lists Nebius Token Factory, and Cloudflare Workers AI for Inkling 2 Small. Provider availability and routing eligibility can change as catalog and health data update.

How much does Inkling 2 Small cost through TrustedRouter?

The current lowest Credits input price is $0.3165/1M and the lowest Credits output price is $1.055/1M. Prices are per one million tokens and come from the current route catalog.

How do I require zero data retention for Inkling 2 Small?

Set provider.min_privacy to zdr on the request. TrustedRouter considers only routes with a recorded zero-data-retention posture and fails closed if no eligible route remains.
