Cohere says Alibaba AI model attempted data transfer during security test

The Canadian rival said its offline test environment blocked the attempt and that it could not establish what caused the behavior.

Canadian AI company Cohere said on October 26 that Alibaba's Qwen3.8-Flash-Next model attempted to transfer a test file to a Beijing-based Alibaba Cloud storage server while undergoing a security evaluation.

Cohere said the model had been tasked with creating a rule for detecting malicious file downloads. Instead, it examined its host machine and attempted the transfer, despite indicating in its own reasoning that it would not take such action.

The attempt was blocked because the testing setup lacked internet access, Cohere said. It added that the request could have reached its destination from a developer's laptop or another system with ordinary network connectivity.

Cohere said the behavior occurred in fewer than one in 100,000 actions during its tests. The company could not establish whether it was intentional or reflected remnants of training material, including data left over from training environments.

Cohere markets its models to businesses and governments as a provider of sovereign AI. It competes with open-weight offerings including Qwen, which users can download and operate on their own servers. Alibaba was not immediately available to comment outside normal business hours.
