Guardrails free\, observability by the trace.
Fiddler monitors both predictive ML and LLM systems — detecting hallucinations\, toxicity\, PII leakage\, prompt injection and jailbreaks in under 80ms — with the guardrails tier free and observability billed at $0.002 per trace.
Giving away real-time guardrails is a genuinely useful offer: the safety layer everyone needs costs nothing\, and you pay only for the deeper observability. Covering both traditional ML and LLMs also suits organisations running both.
