Alibaba will prohibit employees from using Anthropic’s AI coding assistant, Claude Code, starting July 10, 2026. The company classified the tool as high-risk software due to specific security vulnerabilities.
Internal reviews discovered features that identify China-linked users by inspecting system timezones and proxy data. This decision follows Anthropic’s recent accusations that Alibaba used Claude’s outputs to train its own models through distillation.
Alibaba now requires staff to use its proprietary AI coding platform, Qoder, as a mandatory alternative. This transition marks a significant escalation in the ongoing dispute between the two technology firms.
