Show HN: Strata – an expressive semantic layer that can say no to your LLM
Strata is a new semantic layer designed to work with large language models, offering a way to enforce constraints and reject unsuitable outputs. By providing a structured interface, it lets developers define rules and policies that the model must follow, improving safety and reliability. The project, shared on Hacker News, aims to make LLMs more controllable for real‑world applications.
