Frequently Asked Questions

What is Lutflow's license?

Lutflow is source-available under the Business Source License 1.1 (BSL 1.1). You can inspect and modify the code, but there are commercial usage restrictions.

What happens if I exceed my budget?

Lutflow's measurement tools are completely read-only and will never block or drop traffic on their own. You have full control over the enforcement policies you write on top of our telemetry. If you configure a budget limit, you decide what happens when it's reached (e.g., dropping requests, alerting, falling back to a smaller model).

Will Sentinel break my cluster?

No. Sentinel is designed as an ultra-lightweight, out-of-band agent. It runs with minimal privileges required for observation and does not sit in the critical path of your inference requests. Even if Sentinel encounters an issue, your LLMs will continue serving traffic uninterrupted.

Do I need special hardware to run Lutflow?

Lutflow works out of the box with standard NVIDIA GPUs. The SDK processes telemetry natively and only depends on standard metrics available on these environments.
