arXiv:2606.18521v1 Announce Type: cross Abstract: Reinforcement Learning with Verifiable Reward (RLVR) has emerged as a powerful post-training paradigm that surpasses Supervised Fine-Tuning (SFT) in eliciting reasoning intelligence and resisting catastrophic forgetting. Recent studies further reveal that RLVR induces highly sparse and off-principal parameter updates compared to SFT. This naturally raises the question: does such sparsity make RLVR models more amenable to model merging? If so, model merging would offer a scalable, training-free path to aggregate diverse reasoning capabilities fr
The proliferation of advanced AI models necessitates efficient methods for combining their diverse capabilities, making research into model merging particularly relevant.
This research provides a potential pathway to significantly enhance AI model development and deployment by enabling scalable aggregation of reasoning capabilities without extensive re-training.
The understanding that RLVR models might be more amenable to merging could lead to new architectures and deployment strategies for AI, favoring modular growth over monolithic re-training.
