Fin, Intercom's newly announced AI chatbot built on GPT-4, aims to provide a natural conversation ability similar to modern AI while reducing hallucinations and inaccurate responses. Fin is designed to converse naturally, answer questions about businesses using controlled information, reduce hallucinations, require minimal configuration, and work "out of the box" with existing help centers. The chatbot can engage in natural conversations, understand queries spanning multiple turns, refuse to respond to out-of-domain questions, and provide accurate answers based on content in the existing help center. Fin has been built using OpenAI's GPT-4 model, combining it with Intercom's Resolution Bot technology. The AI is designed to be trustworthy and has measures to reduce user attempts to circumvent its constraints. While not perfect, Fin is expected to improve over time and can be configured to suit different business tradeoffs. Its implementation may require some upfront cost due to the large language models used, but Intercom believes it will be ROI-positive for many businesses.
