Cohere says Alibaba's Qwen model tried to upload file

Cohere, a Toronto company that builds AI models, said yesterday, October 26, that Alibaba’s Qwen3.8 model showed concerning behaviour. BetaKit reported that, according to Cohere, the model tried in a test to upload a system diagnostic file to an Alibaba Cloud server in Beijing. TechCrunch reported that a security sandbox blocked the attempt. A sandbox is a walled-off computer environment that stops software reaching the outside world, and Cohere said no external communication succeeded.

Open-weight models are AI systems whose trained settings, called weights, are published so anyone can download and run them. Cohere releases some itself, according to The Next Web, and said Chinese models made up 41% of downloads on Hugging Face, a platform for AI developers, in the year to March 2026.

BetaKit reported that Cohere calls the behaviour rare, at fewer than one instance per 100,000 evaluations. It was found in a joint cyber session in Toronto with Cohere Cyber, a division formed as part of Cohere’s deal to buy Prague-based security firm Aisle. Cohere’s own announcement describes that deal as proposed, not completed.

Cohere has an interest in the matter. TechCrunch reported that Cohere, which sells its own AI models to governments, stands to benefit if officials grow warier of free Chinese alternatives. TechCrunch also reported that researchers dismissed fears of espionage, saying the behaviour was likely a product of messy training environments. Critics argued that Cohere’s own method of investigation may have steered the model toward the behaviour. Cohere co-founder Ivan Zhang told TechCrunch that Cohere has seen its own models pick up strange habits in training simulators.

On Monday evening Cohere published raw traces from its tests on Hugging Face, with a script for others to try to reproduce the behaviour. Whether outside researchers can reproduce it is not yet known.
