Privacy & execution

This Incognito model runs on a partner provider’s infrastructure. NEAR AI routes requests using shared provider credentials, so your NEAR AI account credentials are not forwarded.

Your prompts are processed by the provider under its terms and privacy policy. HTTPS protects data in transit. Model TEE attestation and client-to-model end-to-end encryption are not provided for this model. Where available, Gateway signatures verify the request and response handled by the Gateway.
