Anthropic has elucidated its policy, stating that the monthly API quotas available to subscribers of the Claude Max and Team plans can be directly utilized with the Claude Agent SDK, Claude-p commands, Claude API, Claude Managed Agents, as well as all third-party applications that employ related technologies. This step has thoroughly dispelled developers' worries regarding potential platform policy alterations. The policy resolves the long-standing issue of double-charging for both users and developers within the large model application ecosystem, introducing a Bring-Your-Own-Subscription (BYOS) model. Under this model, users require only a single subscription to seamlessly use it across diverse third-party tools without incurring extra charges; developers, too, are relieved from bearing API call expenses, enabling them to concentrate on product innovation. Anthropic's approach closely aligns the interests of developers worldwide with its own, harnessing the flourishing developer ecosystem to propel the growth of its Agent ecosystem, thereby propelling the large model competition into a new era of ecological rivalry. This move is hailed as the 'open moment' akin to the App Store in the large model era and is anticipated to give rise to a plethora of innovative Agent applications based on Claude.
