@technooptimist: Palo Alto Networks chairman and CEO Nikesh Arora explains why his cybersecurity company prefers open-weight AI models over closed systems. Open-weight models give companies access to a model's parameters, allowing them to adapt and retrain the technology for their own needs. Arora also argues that this makes it possible to inspect the system's reasoning. That matters in industries like finance and healthcare, where companies must explain, audit and verify what AI has done. Arora says blaming an unexplained decision on the IT team's model won't satisfy regulators.
