PlantVLM-Edge adapts vision-language models for offline agricultural question answering, so growers can ask follow-up questions without sending crop images to the cloud. The authors fine-tune language backbones with LoRA, then quantize their linear layers and serve them locally. On Jetson AGX Orin, Qwen3-VL-2B W4A16-AWQ retained 98.6% of full-precision ROUGE-L, a text-overlap score, not diagnostic accuracy.
