Multi Backend Inference Execution With Pluggable Execution Providers

via “configurable provider system for llm, embedding, and database backends”

SoTA production-ready AI retrieval system. Agentic Retrieval-Augmented Generation (RAG) with a RESTful API.

Unique: Implements provider interfaces as abstract base classes with concrete implementations for each backend, enabling compile-time type safety while maintaining runtime flexibility. Configuration is declarative (TOML) rather than programmatic, allowing non-developers to switch providers.

vs others: More flexible than LangChain's provider system because providers are swappable at runtime via configuration; more comprehensive than Pinecone because it abstracts LLM and embedding providers, not just vector storage.
