The authors say this phase can take more than 90% of runtime when models produce long chain-of-thought outputs. Existing tools also force a trade-off. TRL, DeepSpeed-Chat and ColossalChat are approachable but weak at inference… 2. **[REINFORCE++: Stabilizing Critic-Free Policy Optimization with Global Advantage Normalization](https://md.research.elamur.ai/free/en/papers/hu-2025-reinforce-stabilizing-critic-free-policy/)** *(2025 · 104 citations)* Critic-free reinforcement learning methods for aligning LLMs, such as GRPO and RLOO, avoid the memory and compute cost of PPO's value network. 3. **[ProRL: Prolonged Reinforcement Learning Expands Reasoning Boundaries in Large Language Models](https://md.research.elamur.ai/free/en/papers/liu-2025-prorl-prolonged-reinforcement-learning-expands/)** *(2025 · 58 citations)* Researchers disagree on whether RL with verifiable rewards teaches LLMs new reasoning or only makes already-reachable answers more likely. ## Co-authors here 12 of 14 co-authors with a page, the most papers together first. - [Jason Klein Liu](https://md.research.elamur.ai/free/en/authors/jason-klein-liu/) ×2 - [Wei Shen](https://md.research.elamur.ai/free/en/authors/wei-shen/) ×2 - [Bin Chen](https://md.research.elamur.ai/free/en/authors/bin-chen/) - [Hao Chen](https://md.research.elamur.ai/free/en/authors/hao-chen/) - [Haoran Wang](https://md.research.elamur.ai/free/en/authors/haoran-wang/) - [Haotian Xu](https://md.research.elamur.ai/free/en/authors/haotian-xu/) - [Jan Kautz](https://md.research.elamur.ai/free/en/authors/jan-kautz/) - [Shizhe Diao](https://md.research.elamur.ai/free/en/authors/shizhe-diao/) - [Weixun Wang](https://md.research.elamur.ai/free/en/authors/weixun-wang/) - [Xibin Wu](https://md.research.elamur.ai/free/en/authors/xibin-wu/) - [Ximing Lu](https://md.research.elamur.ai/free/en/authors/ximing-lu/) - [Xin Dong](https://md.research.elamur.ai/free/en/authors/xin-dong/) ## Venues Where their works here were published, the most works first, with the editions of those that have a page. - [Conference on Neural Information Processing Systems (NeurIPS)](https://md.research.elamur.ai/free/en/venues/neural-information-processing-systems/): [NeurIPS 2025](https://md.research.elamur.ai/free/en/venues/neural-information-processing-systems/2025/) ## Cited by Papers of our library cite their works 298 times (of the 149,439 papers whose bibliographies we read); [79 citing papers with a page here →](https://md.research.elamur.ai/free/en/authors/jian-hu/cited-by/).
