Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

Unreleased

Fixed

  • #58: Fix install on Mac OS 13.
  • #55: Fix bug in example causing config.py to crash on computers with no CUDA-enabled GPUs.
  • Fixed the model name initialization for LLMs that use the model kwarg.
  • Fixed the Cohere prompt templates.

[0.3.0] - 2023-06-30

Added

  • Support for defining subflows.
  • Improved support for customizing LLM prompts
    • Support for using filters to change how variables are included in a prompt template.
    • Output parsers for prompt templates.
    • The verbose_v1 formatter and output parser to be used for smaller models that don't understand Colang very well in a few-shot manner.
    • Support for including context variables in prompt templates.
    • Support for chat models i.e. prompting with a sequence of messages.
  • Experimental support for allowing the LLM to generate multi-step flows.
  • Example of using Llama Index from a guardrails configuration (#40).
  • Example for using HuggingFace Endpoint LLMs with a guardrails configuration.
  • Example for using HuggingFace Pipeline LLMs with a guardrails configuration.
  • Support to alter LLM parameters passed as model_kwargs in LangChain.
  • CLI tool for running evaluations on the different steps (e.g., canonical form generation, next steps, bot message) and on existing rails implementation (e.g., moderation, jailbreak, fact-checking, and hallucination).
  • Initial evaluation results for text-davinci-003 and gpt-3.5-turbo.
  • The lowest_temperature can be set through the guardrails config (to be used for deterministic tasks).

Changed

  • The core templates now use Jinja2 as the rendering engines.
  • Improved the internal prompting architecture, now using an LLM Task Manager.

Fixed

  • Fixed bug related to invoking a chain with multiple output keys.
  • Fixed bug related to tracking the output stats.
  • #51: Bug fix - avoid str concat with None when logging user_intent.
  • #54: Fix UTF-8 encoding issue and add embedding model configuration.

[0.2.0] - 2023-05-31

Added

Changed

  • Improved the logging output for Chat CLI (clear events stream, prompts, completion, timing information).
  • Updated system actions to use temperature 0 where it makes sense, e.g., canonical form generation, next step generation, fact checking, etc.
  • Excluded the default system flows from the "next step generation" prompt.
  • Updated langchain to 0.0.167.

Fixed

  • Fixed initialization of LangChain tools.
  • Fixed the overriding of general instructions #7.
  • Fixed action parameters inspection bug #2.
  • Fixed bug related to multi-turn flows #13.
  • Fixed Wolfram Alpha error reporting in the sample execution rail.

[0.1.0] - 2023-04-25

Added

  • First alpha release.
