Strata

A new tool called Strata has been launched as a semantic layer for AI applications, designed to sit between large language models and data. Its distinguishing feature is the ability to reject requests from an LLM when a query cannot be answered accurately or falls outside defined semantics, rather than allowing the model to fabricate an answer. The launch is drawing attention on Hacker News, where developers are discussing approaches to grounding LLM outputs in structured, trustworthy data.
