Welcome to Tech Beat, your daily look at what's moving in the world of technology.
NASA's X-fifty-nine quiet supersonic aircraft has crossed two significant thresholds, hitting target speed and altitude milestones that put it on track for its first flights over American communities. The program's goal is to demonstrate that supersonic travel doesn't have to rattle windows or rattle nerves, potentially reshaping the future of commercial aviation.
Shifting to artificial intelligence, OpenRouter has published research claiming its Fusion approach outperforms frontier model performance by combining outputs across multiple large language models. If the benchmarks hold up under scrutiny, it raises a genuinely interesting question about whether blending models could matter as much as building bigger ones.
And on the research front, a new paper out of arXiv introduces Still, a technique for compressing the key-value cache used in large language models during a single forward pass. That may sound deeply technical, but the practical stakes are real — more efficient memory use means faster, cheaper AI inference, which touches everything from your phone to the data centers powering the tools millions use daily.
