I got Gemma 4 running directly inside Godot using only GDScript and Vulkan compute shaders

I wanted to see if an LLM could run inside Godot without llama.cpp, Python, a server, or a GDExtension. It works. This Godot 4.7 project runs gemma-4-E2B-it-Q4_K_M.gguf locally. The model calculations run in Vulkan compute shaders, while GDScript handles GGUF loading, tokenization, sampling, the KV
