What is Prem AI?
Sovereign models on-premise with encryption.
Who is Prem AI best for?
Prem AI is best for regulated companies that need AI models on data the provider cannot see or keep.
Sensitive data in regulated sectors
Confidential inference runs models on encrypted GPUs with hardware attestation, and Prem says even it cannot read the data.
Apps built on the OpenAI SDK
The zero-data-retention API is OpenAI-compatible, so an existing app can switch by changing the base URL and API key.
EU or UK data residency
Zero-data-retention models run in EU or UK regions and keep no state between requests.
Models inside your own network
Prem also deploys models on-premise inside a client's own perimeter, for teams that cannot use public cloud AI.
How much does Prem AI cost?
Prem AI charges pay-as-you-go API prices per model from a prepaid balance, from $0.16 per million input tokens for encrypted (confidential) inference and $0.22 for the cheapest zero-data-retention chat models.
