SpaceXAI Releases Grok 4.6: A 500K-Context Frontier Model Tuned for Long-Running Agents, Coding, and Knowledge Work

MarkTechPost 2 months ago 16 ● 3 sources

SpaceXAI released Grok 4.6 as a post-training upgrade to Grok 4.5, keeping the same base model but extending supplemental training and adding regenerated supervised fine-tuning plus reinforcement learning for long-running agent tasks. Grok 4.6 supports 500,000 context tokens and scores 61 on the Artificial Analysis Intelligence Index, up from 56 for Grok 4.5. The result is improved long-horizon task behavior and broader availability via the xAI API, Cursor, Grok Build, and routing partners, while there is still no open-weights or self-hosting option.

When Unlearning Is Free: Leveraging Low Influence Points to Reduce Computational Costs

Apple Machine Learning Research 2 months ago 31

The authors propose an unlearning method that uses influence functions to find training points with negligible impact and then unlearns only the relevant subset. Up to about 50 percent computational savings are reported on real-world empirical examples by shrinking the dataset before unlearning. The approach changes unlearning by avoiding processing every point in the forget set equally, reducing compute cost.
