Evie makes extensive use of AI models throughout the application. She currently uses 3 types of models:

• Embedding Models: Embedding models allow to index your library of information – wether that’s pages from your website, intranet or documents in your experts’ library – semantically, and it allows to search for related documents when questions are asked.
• ASR (Automatic Speech Recognition): In order to transcribe audio files (e.g. podcasts) or videos so they can get indexed, Evie uses specific AI models.
• LLMs (Large Language Models): These models realise a.o. the conversational elements (the chatbot itself). To be complete, 9 different proprietary algorithms using LLMs are used throughout the application.

Throughout development of the application, we have chosen to support different models when possible, allowing each tenant (a company using the system) to choose it’s model of preference.

This list will expand and might change in the future, as evolution in this domain is exponential.
