When requested by the user, or as part of any standard pattern of self-identification, AI-powered chatbots should be able to clearly and accurately identify what LLM or other technology they are using. If the models are proprietary or open-source, they should be identified as such.
Where an AI-powered chatbot is based on an LLM or similar technology, they should be able to link to model cards or other equivalent official documentation that describes the models abilities, limitations, risks, etc.
