UnverifiedGRPO (Group Relative Policy Optimization) is better suited than traditional RLHF for multi-step decision-making scenarios because it can simultaneously evaluate the relative merits of multiple execution paths.78% similarUnverifiedGRPO (Group Relative Policy Optimization) is an improved variant of PPO that requires no additional value network training; instead, it calculates the reward signal by sampling a group of responses to the same question and using intra-group relative performance as a baseline.77% similarUnverifiedAt the training level, reasoning-enhanced models typically leverage reinforcement learning algorithms such as GRPO (Group Relative Policy Optimization), using the correctness of the final answer as the reward signal72% similarUnverifiedRL algorithms commonly used for LLMs such as GRPO and PPO rely on Monte Carlo sampling to estimate policy gradients.69% similarUnverifiedThe Grok series adopts a Mixture of Experts (MoE) architecture, expanding parameter scale while maintaining lower inference costs by dynamically activating different expert sub-networks.68% similar
