Guardrails AI, in its latest release version 0.2.0, introduces several enhancements aimed at improving the assurance and quality control of AI applications. This update includes native support for Pydantic, allowing developers to embed Guardrails directly into their large language model (LLM) applications, and introduces a new ProvenanceV1 guardrail for validating LLM outputs with another LLM. The release also features improvements for guarding string outputs and a refactoring of validators and string templates to enhance usability and flexibility. Breaking changes in string templating require variable references to be updated, and choice tags have been simplified to align with OpenAPI standards. Additionally, comprehensive documentation updates and a migration guide are provided to assist users in transitioning to the new version. The release encourages community engagement through various platforms and highlights new open-source validators for advanced PII detection and jailbreak prevention.
