Granite Switch is a tool from IBM Research that allows composing multiple LoRA adapters into a single deployable LLM checkpoint, enabling task-specific fine-tuning without requiring separate models per task. Its novel switch-layer mechanism and KV cache normalization make adapter composition practical and inference-efficient, addressing a significant operational pain point in deploying fine-tuned models.
