Researchers have developed a new inference-time architectural enhancement called "recirculation" for foundation models that significantly reduces perplexity and improves accuracy on generation and reasoning tasks. This technique introduces a form of recurrence, allowing models to act as dynamical systems and track belief states without adding latency during generation, though it requires serial processing in the prefill phase. An adaptive variant of recirculation, which requires only light hyperparameter tuning while keeping original model weights frozen, achieved a 23% reduction in perplexity and a 21% increase in accuracy on the Gemma3 family of models.
