… AI-generated summary RL post-training of frontier language models is increasingly bottlenecked by autoregressive rollout generation , making rollout acceleration a central systems challenge. …
… One approach, reinforcement learning, rewards the model through trial and error and can work well, but it is costly because the model must repeatedly generate full back-and-forth conversations during training. …
… GE-Sim 2.0 tops the public WorldArena leaderboard at only 2B parameters, outperforming both dedicated robotic world models and closed-source general video generators, and policies trained against its rollouts and rewards translate into measurable real-world gains, establishing GE-Sim 2.0 as a pract… …
… Could you share learning curves or metrics for the 120B model? The article mentions both vLLM and SGLang. Which engine is used for rollouts in the final experiments? …

… We then fine-tune the full decision--draft--reflect rollout with reinforcement learning RL , assigning terminal driving reward to the final post-edit trajectory and propagating policy-gradient credit through full-rollout transitions. …
… Interactive world models require controllable, causal, and low-latency rollout , which in practice demands a full pipeline spanning data construction, controllable fine-tuning, autoregressive training, few-step distillation, and streaming inference. …

… We further propose Consistency-model Group Relative Policy Optimization CM-GRPO , which reformulates a consistency sampling step as a conditional Gaussian transition and applies online Reinforcement Learning RL directly to this kernel, avoiding the Euler-Maruyama auxiliary process adopted in prior … …
