- Participants questioned the novelty of GRPO (presumably a reinforcement-learning objective), arguing that averaging benchmark results and training directly on them seems obvious, seeking clarification on why it is being presented as a breakthrough.  
- Paul Christiano’s essay “Why Capability Evals Are Pro-Safety” was being read, indicating ongoing interest in evaluation frameworks that could steer advanced AI development toward safer trajectories.
