cpp-langchain implements core features from the LangChain ecosystem in C++. Developers can wrap calls to large language models, define prompt templates, assemble chains, and orchestrate agents that call external tools or APIs. It includes memory modules for maintaining conversational state, embeddings support for similarity search, and vector database integrations. The modular design lets you customize each component—LLM clients, prompt strategies, memory backends, and toolkits—to suit specific use cases. By providing a header-only library and CMake support, cpp-langchain simplifies compiling native AI applications across Windows, Linux, and macOS platforms without requiring Python runtimes.

Milvus is an open-source vector database specifically designed for managing AI workloads. It provides high-performance storage and retrieval of embeddings and other vector data types, enabling efficient similarity searches across large datasets. The platform supports various machine learning and deep learning frameworks, allowing users to seamlessly integrate Milvus into their AI applications for real-time inference and analytics. With features like distributed architecture, automatic scaling, and support for different index types, Milvus is tailored to meet the demands of modern AI solutions.
