AI Regulation Criteria Vague Without Better Non-Lab Benchmarks
By
–
That doesn't mean that there should not be regulation and vetting, but it does suggest that is hard to write a criteria right now that is not somewhat vague. More R&D into non-lab benchmarks is urgently needed. We have remarkably few good ones that are unsaturated and clear.

AI Regulation Hampered by Poor Benchmarks and Risk Metrics
By
–
A challenge with AI regulation and vetting is how bad our benchmarks of AI model performance and risks are. There is no benchmark for risks and red-teaming requires experiments from dedicated specialist organizations & is not easy to put metrics around. No clear objective numbers

NVIDIA Megatron Core Adds Muon and Advanced Optimizers for LLM Training
By
–
Training Kimi K2 and Qwen3 30B-scale models efficiently requires more than standard data-parallel tricks. NVIDIA Megatron Core now provides end-to-end support for emerging higher-order optimizers like Muon, alongside research optimizers such as MOP and REKLS, to push training

"Accelerating RL Post-Training Rollouts via System-Integrated Speculative Decoding" Speculative decoding for RL rollouts! This paper speeds up post-training without changing the target policy’s sampling distribution. So a draft model proposes multiple tokens, and the policy
