Why are we so expensive?
We are stable and mostly use official providers — no unreliable proxies or shared API pools. You get direct, production-grade access to every model.
Built so you never
think about it.
The infrastructure layer that gets out of your way. Private by default, encrypted everywhere, and priced at exactly what the model costs.
Talk to the team on Discorddiscord.gg/zenllmWe never log, store, or train on your prompts or completions. Requests pass through and disappear.
Data is encrypted at rest and in transit. Keys are hashed and shown exactly once.
Works with the OpenAI, Anthropic, and Responses APIs. Swap the base URL and keep your code.
Billed at the underlying provider's list price. No hidden markup, no surprise invoices.
