It supports extensive capabilities including fine-tuning, TTS (Text-To-Speech), and natural language generation; pick KuiperLLama if kuiperLLama is an inference framework project for LLama2/3 and Qwen2.5 models using C++ and CUDA. It provides guidance to implement a custom inference engine from scratch. [CosyVoice](https://funaudiollm.github.io/cosyvoice3) reports 23k GitHub stars, 2.6k forks, and 719 open issues, last pushed May 25, 2026. [KuiperLLama](https://github.com/zjhellofss/KuiperLLama) has 568 stars, 143 forks, and 10 open issues, last pushed Oct 28, 2025.
