About

OGX runs as an HTTP server, or can be imported as a Python library, and exposes OpenAI-compatible endpoints for chat completions, the Responses API, embeddings, vector stores, files and batches. The Responses API covers tool calling, MCP server integration and file search. Providers are pluggable, so backends such as Ollama, vLLM, Bedrock or Azure can be changed without changing application code. It also serves Anthropic Messages and Google GenAI interaction endpoints.

Use cases: model-inference, agent-orchestration
