In the world of artificial intelligence (AI), developers often face a challenge – ensuring the accuracy and quality of outputs generated by large language models (LLMs). The outputs, such as generated text or code, need to be accurate, structured, and aligned with specific requirements. Without proper validation, these outputs may contain biases, bugs, or other usability issues.
Guardrails, an open-source Python package, is a tool designed to add a layer of assurance to the validation and correction of LLM outputs. This tool introduces the concept of a “rail spec,” a human-readable file format (.rail) that allows users to define the expected structure and types of LLM outputs. It also includes quality criteria, such as checking for biases in generated text or bugs in code. The tool utilizes validators to enforce these criteria and takes corrective actions, such as reasking the LLM when validation fails.
One of Guardrails’ notable features is its compatibility with various LLMs, including popular ones like OpenAI’s GPT and Anthropic’s Claude, as well as any language model available on Hugging Face.
The tool also offers Pydantic-style validation, ensuring that the outputs conform to the specified structure and predefined variable types. Guardrails also supports streaming, allowing users to receive validations in real-time without waiting for the entire process to complete.
Guardrails is a valuable tool for developers striving to enhance AI-generated content’s accuracy, relevance, and quality. With Guardrails, developers can navigate the challenges of ensuring reliable AI outputs with greater confidence and efficiency.
