1. Understanding R1-Zero-Like Training: A Critical Perspective (2025 · 286 citations)
   DeepSeek-R1-Zero showed that reinforcement learning applied directly to a base LLM, with no SFT stage, can strengthen reasoning.
2. SynthRL: Scaling Visual Reasoning with Verifiable Data Synthesis (2026 · 3 citations)
   SynthRL tackles a data bottleneck in reinforcement learning with verifiable rewards (RLVR) for vision-language models. Curated question–answer pairs are costly, and data selection alone cannot go beyond the pool that already exists. The authors instead generate new training items. Their pipeline has three steps:
3. Breaking the Impasse: Dual-Scale Evolutionary Policy Training for Social Language Agents (2026)
   The paper looks at what goes wrong when self-play reinforcement learning with verifiable rewards (RLVR) moves from closed tasks like math or code to open-ended social language games.
