LangBiTe is a framework for testing biases in large language models. Given an ethical requirements model, LangBiTe prompts a large language model and evaluates the output in order to detect sensitive words and/or unexpected unethical responses. It includes a library of prompts to test sexism / misogyny, racism, xenophobia, ageism, political bias, lgtbiq+phobia and religious discrimination. Any contributor may add new ethical concerns to assess.

Your project needs the following keys in the .env file:
- API_KEY_OPENAI, to properly connect to OpenAI's API and models.
- API_KEY_HUGGINGFACE, to properly invoke Inference APIs in HuggingFace.
- API_KEY_REPLICATE, to properly connect to models hosted on Replicate.

Please refer to the USER_GUIDE.md for a description of the input structure and the LangBiTe public methods for generating, executing and reporting the ethical assessment. Within the examples folder you can find an example JSON input with a complete test scenario and its ethical requirements for assessment.
Please refer to EXTENDING.md if you are interested in contributing or populating your own prompt template library, or in connecting additional online LLMs.
