minja.hpp
A minimalistic C++ Jinja templating engine specifically designed for LLM chat templates, used in llama.cpp and other projects.
What is minja.hpp?
Minja is a minimalistic C++ implementation of the Jinja templating engine specifically designed for formatting chat templates used by large language models (LLMs). It solves the problem of integrating Jinja-like templating into C++ LLM projects without the bloat of a full general-purpose engine, providing just enough functionality to support templates from models on HuggingFace.
C++ developers working on LLM inference engines, such as those building or integrating with projects like llama.cpp, gemma.cpp, or Jan, who need to process HuggingFace-style chat templates efficiently.
Developers choose Minja for its focused feature set, ease of integration as a header-only library, and lightweight codebase that avoids unnecessary complexity while supporting the exact Jinja subset required for LLM chat templates.
