2025/11/29

The research proposes Parallel Scaling (PARSCALE) as a novel, efficient strategy to enhance Large Language Model (LLM) capacity by increasing parallel computation rather than merely growing the parameter count. This method reuses existing model parameters by feeding multiple parallel input streams (differentiated by learned prefixes) and dynamically combining their outputs into a single prediction. Through extensive testing, the paper develops a new scaling law, showing that scaling computation by a
