Retention Verification: no verified privacy claim. Engy's October 21 policy distinguishes its no-content-logging gateway from independent GPU workers. End-to-end ZDR requires provider.zdr=true or a verified account/key setting; TrustedRouter has not verified that setting for this route. Requests without it may reach independently operated workers.

Retention Zero data retention.

TrustedRouter currently publishes hosted chat routes and adapts Responses to chat completions. Stateful Responses, AI Assistants with conversation history, third-party models and /v2/ai/embeddings are outside this ZDR scope. OpenAI-compatible embeddings may run in any region. DPA 3.1 restricts training of models available to others, with exceptions for written opt-in or data de-identified under 3.5. This is policy-backed ZDR, not confidential compute or verified end-to-end attestation. Location Operator country: US Headquarters / registered office: Austin, Texas, United States.

Inference: Multi-region, dynamically routed among the model's available Telnyx regions; no fixed inference-region commitment on this TrustedRouter route. Provider-wide GPU region set.

Questions
What model ID should I use for Kimi K3.1 Pro?
Use moonshotai/kimi-k3.1-pro as the model field with the TrustedRouter OpenAI-compatible API. Credits routing and provider fallback happen behind that model ID.
Do you log my prompts or outputs?
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 Kimi K3.1 Pro?
TrustedRouter currently lists Tinfoil, Nebius Token Factory, Telnyx, Baseten, Sail Research, Featherless AI, Kimi, DeepInfra, Fireworks AI, Novita AI, Engy, AkashML, Arcee AI, Lyceum, and Boundless for Kimi K3.1 Pro. Provider availability and routing eligibility can change as catalog and health data update.
How much does Kimi K3.1 Pro cost through TrustedRouter?
The current lowest Credits input price is $1.477/1M and the lowest Credits output price is $7.385/1M. Prices are per one million tokens and come from the current route catalog.
How do I require zero data retention for Kimi K3.1 Pro?
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.
