Experimental

This is a collection of C++ libraries designed for developers who are building applications that use large language models (LLMs). It provides tools for various LLM-related tasks, like managing conversational turns, implementing robust retries, or estimating token costs. Developers can pick and choose specific functionalities to integrate LLM capabilities directly into their C++ applications without external dependencies like Python.

Use this if you are a C++ developer building a native application and need fine-grained control over LLM interactions, streaming, caching, or structured output.

Not ideal if you are not a C++ developer or prefer using high-level SDKs and package managers for LLM integration.
