OGX: Open-Source Server for Vendor-Neutral Generative AI Applications

Developing generative AI applications often involves integrating various models, databases, and safety features from different vendors, leading to complex and vendor-locked architectures. To address this, OGX (Open GenAI Stack) has been introduced as an open-source AI application server and Python library. Its core purpose is to provide a unified API surface for building agentic AI applications, such as RAG pipelines and multi-turn agents. OGX allows developers to write application code once and deploy it with any combination of inference engine, vector database, and safety backend, without requiring changes to the application logic. It implements APIs from leading AI labs like OpenAI, Anthropic, and Google, and supports over 20 inference providers and 13 vector store backends. With a companion Kubernetes Operator for production, OGX serves as a model-agnostic backend, already powering tools like Claude Code and OpenHands, and has garnered significant community traction with over 8,400 GitHub stars.
