0.14.0#

Features#

Breaking Changes#

  • Removed support for the NeMo LLM Service, nemollm. This provider reached end-of-life on February 5, 2025.

  • The HuggingFacePipelineCompatible provider is refactored. Previously, the class was available from the nemoguardrails.llm.providers package. In this release, the class is moved to the nemoguardrails.llm.providers.huggingface package.

Fixed Issues#

  • Fixed an issue when tracing is enabled. Previously, the response was replaced when tracing is enabled and could cause a crash or exception. In this release, the response is not modified when tracing is enabled. For more information, refer to PR #1103.

  • Fixed an issue with the self check output flow. Previously, the stop instruction was not executed when enable_rails_exceptions was enabled. In this release, the stop instruction correctly regardless of the enable_rails_execptions value. For more information, refer to PR #1126.

  • Previously, the model specification in the guardrails configuration file, config.yml, did not validate the model name. In this release you must specify the model name in the model top-level field or as model or model_name in the parameters field. For more information, refer to PR #1084.
