Strata

Developers on Hacker News are discussing Strata, a newly launched semantic layer designed to sit between large language models and data. Its distinguishing feature is the ability to refuse invalid or nonsensical queries from an LLM rather than guessing an answer, aiming to reduce hallucinated results in data analysis workflows.

Developer Ajo has launched Strata, a semantic layer designed to give large language models structured, governed access to business data. He says his four years at Netflix working on self-service analytics for non-technical users shaped the product's distinctive design. A notable feature is that Strata can refuse LLM requests that violate its semantic rules, aiming to keep AI-driven data queries accurate and safe.
