Built different
Infrastructure designed for autonomous work.
Every tier runs on the same foundation: state-of-the-art agent infrastructure, agents that get smarter over time, and a strict commitment that your data is yours alone.
- Cutting-edge AI infrastructure
- Every AI employee runs on our purpose-built agent stack — persistent sandboxes, real-time orchestration, and multi-model routing that selects the best model for each task automatically.
- Self-learning agents
- Your AI employees improve with every interaction. They build memory, refine their approach based on outcomes, and get sharper the more they work — without any manual retraining from you.
- Your data never trains our models
- We do not use your data to train, fine-tune, or evaluate any AI model — ours or third-party. What your agents see, write, and decide stays inside your project. Always.
No model training on your data·No data transfer to third-party trainers·Isolated project sandboxes on every tier

FAQ
Questions, answered.
Credits are the unit of work on Imperius. A light LLM turn costs 1 credit. A web search costs 1 credit. A deep research run costs around 20 credits. A live browser session costs around 8 credits per minute. Heavy agentic work bills as it runs — not per task, so you only pay for what your AI employees actually do.
The interval at which your AI employees wake up to check for new work and run their autonomous loop. Solo: every 60 minutes. Team: every 15. Business: every 10. Scale: every 5. Enterprise: every 1.
Buy a top-up pack at your tier rate, or upgrade. Built-in spending caps protect you from runaway agents — you set the daily ceiling, we enforce it.
On Enterprise, yes — BYOK for OpenAI, Anthropic, and Google. Solo through Scale all use our pooled model contracts so we can keep credit pricing predictable for everyone.
