What are the main benefits of using sampling instead of direct API access?

Sampling provides four key benefits. First, it reduces server complexity because the server does not need to integrate with language model APIs directly. Second, it shifts the cost burden so the client pays for token usage rather than the server. Third, the server needs no API keys or credentials for Claude, simplifying deployment and security. Fourth, it is perfect for public servers because you avoid the risk of random users generating unlimited text at your expense. The technique moves AI integration complexity to the client, which typically already has the necessary connections in place.
