“We offer three plans, and we work with customers to find the right fit based on their specific use cases and needs, rather than a one-size-fits-all package. The Free plan includes real-time guardrails powered by Fiddler Centor Models at under 80ms latency , protecting against hallucinations, toxicity, PII/PHI, prompt injection, and jailbreak attempts. The Developer plan is usage-based at $0.002 per trace and adds unified observability for agentic and predictive systems, custom evaluators, and SSO. The Enterprise plan adds enterprise-grade guardrails, flexible deployment (SaaS, VPC, or on-premises), infrastructure scalability, and white-glove support with a named Customer Success Manager and customized onboarding.”
