AlterNet: Adaptive-Depth Mixture-of-Experts with Learned Halting for Elastic Inference

arXiv:2611.08741v1 Announce Type: new Abstract: Most LLM architectures have fixed compute demands determined at training time. We propose a novel architecture that combines the Mixture-of-Experts architecture with shallow experts and a novel dynamic-depth system to make the extent of a forward pass dynamically adjustable. Our approach lets the model automatically determine the compute needed for a given task, paired with a system to scale it down after training without retraining when the execution environment demands faster or cheaper inference.
