About Onyx
Onyx is an open-source AI chat platform designed to serve as a primary interface for enterprise teams to access generative AI. It uniquely connects to an organization's documents, apps, and people while maintaining transparency and security. The platform uses advanced retrieval techniques including hybrid search, retrieval-augmented generation (RAG), contextual retrieval, and LLM-based knowledge graphs to deliver answers grounded in team knowledge. Onyx is targeted at enterprise teams seeking reliable, secure AI assistance without compromising data control or compliance requirements. What distinguishes Onyx is its open-source nature, allowing self-hosting on any infrastructure, combined with benchmarked performance that reportedly outperforms ChatGPT and Claude on real workplace questions. A potential limitation is that as an open-source platform, implementation and maintenance may require more technical expertise compared to fully managed commercial alternatives.
