Guardrails AI has developed a system to enforce structured and high-quality outputs from large language models, addressing a common criticism of LLMs' tendency to deviate from instructions. The system uses a declarative language called RAILs, which defines rules for output structure, prompts, and validation scripts. These RAILs act as a wrapper around LLM API calls, validating the output and re-prompting the model if necessary to ensure adherence to requirements. This approach aims to make LLM outputs more predictable and consistent across different models. AI
