Lucas and Luna dive into a fresh AI angle: the rise of data rejection in model training. Instead of feeding models everything, top labs are now teaching systems to spot and discard low-quality, biased, or poisoned data before it ever touches the weights. Lucas breaks down why this shift matters, pointing to the recent wave of AI chip stocks diverging—NVIDIA up 3.6 percent this week while AMD slipped 1.8 percent—and connects it to the growing cost of compute: when training runs cost millions, you can't afford to waste cycles on garbage data. Luna brings up the Pentagon's new ChatGPT-like tool, questioning how rejection applies to classified data. They also explore practical implications: from smaller open-source models outperforming giants on niche tasks to the rise of data curation as a service. The episode closes with a reflection on how the industry is moving from 'more data, more power' to 'better data, better reasoning.'
