Does 2-Bit Quantization Break On-Device Safety? What an EMNLP 2026 Study Found, and a GGUF Release Gate

TL;DR An EMNLP 2026 Industry Track paper from OptAI Inc. tested what happens to chat-format safety when you shrink a model with GGUF K-quantization and serve it through llama.cpp, the engine behind Ollama. Nine models, four quantization levels, seven attack conditions, 520 harmful instructions. The…
