Developer warns against custom LLM inference engine development

A developer shared their challenging experience building a custom inference engine for large language models, describing the process as "vibecoding." They encountered significant difficulties with debugging, particularly concerning the integration of GGUF quantized models into WebGL2 compute buffers via GLSL within an HTML environment. The developer ultimately advised others to simply clone existing, established projects like llama.cpp due to the complexity and time investment required for custom development. AI

IMPACT Highlights the complexity of building custom LLM inference engines, suggesting that established tools like llama.cpp are more practical for most users.
