LoopGR: Parameter-Efficient Scaling for Generative Recommendation via Recurrent Depth
Brings recurrent depth to generative recommendation with a hierarchical mechanism that alternates a shared generative decoder and a lightweight context updater, plus recurrent trajectory self-distillation from a high-budget teacher to a low-budget student.

Simplified conceptual schematic. Consult the paper for the complete architecture.
- Recurrence family
- Core recurrence
- Depth control
- Configurable recurrent budget; distilled low-budget student
- KV / state strategy
- See paper
Reading note
Outperforms strong generative recommendation baselines and beats an encoder-decoder baseline while reducing model size by up to 52%.
