The company is introducing a paid plan called Claude Pro for its chat experience, which has been popular among users since its launch in July. The new plan offers 5x more usage of the latest model, Claude 2, for a monthly fee of $20 (US) or £18 (UK). This allows subscribers to increase their productivity and access priority support during high-traffic periods, as well as early access to new features. The paid plan also includes additional benefits such as increased file uploads and conversations over longer periods.
