Anthropic is blocking Claude Pro and Max subscribers from using their subscriptions with third-party AI agents like OpenClaw from April 4. Users must switch to pay-as-you-go extra usage billing or the API. The company cites strain on compute resources, as third-party services bypass the prompt cache optimisations its first-party tools use. A single OpenClaw agent running for one day can burn 1,000 to 5,000 USD in API costs. https://venturebeat.com/technology/anthropic-cuts-off-the-ability-to-use-claude-subscriptions-with-openclaw-and #AIagent #AI #GenAI #AgenticAI #Anthropic
