Trust, but Verify: Shreya Rajpal

Shreya Rajpal, CEO of Guardrails AI, argues that large language models require a verification layer to compensate for their non-deterministic nature. She explains that while prototyping works, production apps fail due to hallucinations, prompt injections, and structural errors. Guardrails AI is an open-source framework that wraps LLMs with a validation suite: on output, it checks constraints like provenance (grounding in a source), profanity, and competitor mentions. On violation, it re-asks the model to self-correct or falls back to specified policies. Rajpal demonstrates with a chatbot example where a provenance guardrail catches a hallucinated password setting, then guides the model to a correct answer grounded in help center articles. The framework also supports custom validators, automatic prompt compilation from checks, and integration with external systems like sandboxed SQL databases for code generation.
