Carlos's Debrief

⚡ Quick Summary

**Expert Upcycling** allows sparse Mixture-of-Experts models to grow their expert count during continued pre-training while preserving per-token inference cost, more than tripling gap closure vs random initialization.
**C-GenReg** is a training-free 3D point cloud registration framework that transfers matching into an image domain using a World Foundation Model, achieving strong zero-shot generalization across modalities.
**Abstain-R1** demonstrates that calibrated abstention and post-refusal clarification can be learned through verifiable rewards in small (3B) models, competitive with much larger systems like DeepSeek-R1.
**SmartPhotoCrafter** unifies reasoning, generation, and optimization for photographic image editing using a critic-to-artist pipeline, eliminating the need for explicit human aesthetic instructions.
