Frontier AI research moves into cyber defense as attackers gain speed

SiliconANGLE 1 month ago 20 ● 2 sources

CrowdStrike is shifting frontier AI research toward security operations via a cyber superintelligence lab that turns threat-research knowledge into defense-focused models. In CrowdStrike’s evaluations, the models delivered a 29% higher detection rate and remediated threats six times faster than leading frontier and open-source alternatives. The lab will publish benchmarking and validation work and focus on training, reinforcement learning alignment, and building agentic systems to commoditize defense capabilities beyond a single platform.

AfterQuery reportedly hits $3.2B valuation, becoming Y Combinator’s fastest-ever unicorn

Tech Funding News 1 month ago 31 ● 2 sources

AfterQuery’s valuation reportedly rose from $300M to $3.2B after it raised a Series B, making it Y Combinator’s fastest-ever unicorn. The move happened in five months. The company shifts from training AI agent workflows to funding expert-captured reasoning that becomes datasets and reinforcement-learning environments for AI labs to train on.

REFACTOR-VLA: Unsupervised Library Learning of Typed Motor Programs

Apple Machine Learning Research 1 month ago 40

Researchers introduced REFACTOR-VLA to turn monolithic vision-language-action behavior into reusable typed motor programs learned with a wake/sleep loop. The system clusters motor-program segments in the sleep phase using a Behavioral-Equivalence Kernel driven by rollouts in a learned latent world model trained via a three-phase schedule, and it reports NMI scores for n=3 multi-seeding including 0.915 ± 0.013 on the Goal suite. Performance shifts as a bigger world model (188M to 430M parameters) worsens 4 out of 4 LIBERO benchmark suites while adding an auxiliary InfoNCE contrastive loss in Phase A improves the quality of skill clustering in Phase C.
