 [GPT4All](https://github.com/nomic-ai/gpt4all) is a popular desktop/local LLM runtime with a user-friendly interface and broad model support (GGUF/GGML).
 It enables plug-and-play inference on CPU/GPU without complex setup, but it introduces typical fragilities: schema drift, citation loss, and memory instability.
 This page provides WFGY-based guardrails and reproducible fixes.
