According to CNBC, Alibaba will ban employees from using Anthropic’s artificial intelligence tools for work purposes as of July 10, citing concerns about back-door security risks. People familiar with the matter said Alibaba has put Anthropic’s Claude Code on a high-risk software list and is requiring employees to uninstall Anthropic models and agent products and instead use Alibaba’s own AI assistant, Qoder. The move follows Anthropic’s June letter to the U.S. Senate Committee on Banking, Housing, and Urban Affairs accusing Alibaba of attempting to extract its AI capabilities via what it called “the largest known distillation attack” on it to date; Anthropic’s terms of service bar Chinese companies and other “adversarial nations” from using its models. Alibaba and Anthropic declined to comment.
