Custodian Labs Python SDK FAQ
Do I need to provision any databases or vector stores?+
No, Custodian abstracts storage and retrieval layers; you just add a knowledge base in one line.
How does the Guardian Layer protect PII?+
It detects PII, then either masks, transforms, or reports it according to your chosen mode, never sending raw PII to the model.
Can I switch AI providers without rewriting code?+
Yes, you can change between OpenAI, Anthropic, Mistral or local models with a single configuration change.
Is there a free tier to try the SDK?+
The Basic plan is free and includes 100k tokens, 1k requests, and access to GPT-4o.
What support is available on the paid plan?+
Starter customers get 24/7 priority support, a monthly 1:1 product call, direct roadmap input, and a free compliance assessment.
Can I run Custodian on my own infrastructure?+
Custom plans offer on-premise or private-cloud deployments with dedicated SLA support.
