NVIDIA paired the launch of its Open Agent Safety Platform with a $150 billion expansion of its stock buyback program, reports The Guardian. The board approval increases the total repurchase authorization to $235 billion.

More than 100 organizations were using the platform at launch, including Microsoft, Perplexity, Accenture and JPMorgan Chase.
