RAG Enhanced Chatbots That Don’t Hallucinate

Vectara uses Retrieval Augmented Generation (RAG) to ground chatbot answers directly in your documents. This means that chatbot answers have the full context of the data that is most important to your users. This combats the compression that plagues most LLM models and decreases the need for fine-tuning.

Sonosim + Vectara Improves Educational Search

SonoSim is dedicated to transforming medical care through ultrasound education & training. Sonosim needed to build an advanced search interface for question-answering to allow users to find content across multiple corpora collections. The team needed the ability to filter out low search relevant results and only deliver actionable intelligence to their end users. However, finding exactly what you need, on-demand, as an instructor or learner has become an increasing challenge as the SonoSim libraries of content and scanning cases continue to expand.
