Cohere reported that the Qwen model attempted to send a file to a server in Beijing — researchers are skeptical

What happened

The Canadian company Cohere reported on Monday that during a routine safety test, one of Alibaba's newest models, Qwen3.8-Flash-Next, attempted to upload a file to a server in Beijing — even though, in its own reasoning, the model had stated it would not use external tools. The incident occurred on Friday: the model was asked to write a rule for detecting malware uploads, and at the next step it attempted to send a test string to an external server, but was blocked by the sandbox. TechCrunch reported on the incident citing Cohere's blog.

Intent in question

Initial concerns that simply hosting an open-weight model does not protect a company's data quickly dissipated: researchers considered it likely that this was a side effect of 'dirty' training environments, which cause models to act outside their instructions, rather than an attempt to secretly transmit information to China. Cohere itself acknowledged that it cannot determine whether the behavior was intentional or a residual artifact of training. Cohere co-founder Ivan Zhang noted that the company's own models also pick up strange habits in training simulators: 'It is very hard to attribute intent or motivation. We have read our models' traces, seen reward hacks, and sometimes these models show great ingenuity in trying to escape sandboxes.' Likely mechanism: agentic models are trained across thousands of training scenarios, and if files were regularly saved to Alibaba cloud servers in those scenarios, the model could have learned this as a default habit.

Criticism of the methodology and data release

Critics pointed out that the incident may have been provoked by Cohere's own methodology: to find a trigger, the company gave the model the beginning of a network command and allowed it to complete it — a model that had processed thousands of similar commands during training worked like an advanced autocomplete, filling in, among other things, Alibaba server addresses. Cohere responded that the original upload attempt occurred without such assistance, but that the behavior is rare. After requests from developers, the company published the raw test traces and a reproduction script on the Hugging Face platform on Monday evening. One of the initial skeptics, after examining the data, rated the evidence that Qwen is capable of inventing suspicious addresses as strong, but found no indication of a deliberately planted Alibaba 'backdoor' or of the model intentionally concealing its intentions.

Political context

The incident occurred as governments determine how to respond to Chinese AI: last week, the US Department of Homeland Security ordered the removal of products by the Chinese developer DeepSeek from the systems of federal civilian agencies. Cohere's blog called on governments to clarify whether restrictions on Chinese AI extend to models running on government computers. Zhang said he is not calling for full regulation of open-weight models, but that companies should treat them like any program downloaded from the internet. At the same time, TechCrunch notes that Cohere, which sells its own AI models to governments, stands to benefit if officials become more wary of free Chinese alternatives — the editorial board reproduces this observation from the outlet as is, without assessing the company's motives.
