Alibaba Cloud Bans Anthropic’s Claude, Mandates Shift to Tongyi AI
BABA•Alibaba Cloud sent an internal memo on July 6 instructing employees to delete Anthropic’s Claude from corporate devices, citing potential data leakage and compliance risks. Staff have been directed to transition all generative AI tasks to Alibaba’s Tongyi family of models for development and operational use.
1. Internal Ban on Claude
On July 6, Alibaba Cloud issued an internal memo requiring all employees to remove Anthropic’s Claude generative AI from company devices and cease its use in workflows. The directive applies to code generation, research and content creation tasks where employees had been relying on the third-party platform.
2. Data Security and Compliance Risks
Company leadership cited concerns that uploading proprietary data to Claude’s external servers could breach internal compliance policies and expose confidential information. The ban follows a review of cloud security protocols that flagged potential vulnerabilities in routing sensitive customer and financial data through non-Alibaba AI systems.
3. Strategic Emphasis on Tongyi Models
Employees have been instructed to shift generative AI workloads to Alibaba’s in-house Tongyi family of models, which the firm says are fully integrated with its cloud security framework. This move underscores Alibaba’s push to bolster its proprietary AI offerings and maintain tighter control over data governance.
