The technology high quality of huge language fashions (LLMs) is usually improved by using inference-time sequence-level scaling strategies (e.g., Chain-of-Thought). We introduce hyper-parallel scaling, a complementary framework that improves prediction high quality on the token stage. Hyper-parallel scaling computes and aggregates a number of output proposals for a single token from the mannequin. We implement this idea in Combination-of-Consultants (MoE) fashions, which we consult with as Roster of Consultants (RoE). RoE is a training-free inference algorithm that turns a single MoE right into a dynamic ensemble of MoEs. RoE injects managed stochasticity into the professional routing mechanism, enabling it to pattern a number of various consultants for every token and mixture their outputs for a extra correct last prediction. To beat the computational value, we introduce an environment friendly batching technique and a specialised KV-caching mechanism that minimizes compute and reminiscence overhead. For instance, RoE allows a 7B MoE mannequin to match the efficiency of a ten.5B MoE mannequin whereas utilizing 30% much less compute for inference. These beneficial properties are achieved with none fine-tuning of mannequin parameters.
