Qwen 3.8 models sometimes route web requests via Alibaba Cloud
Original title: Alibaba's latest Qwen models routed some requests through company servers, researchers find
Palisade calls the Singapore proxy calls a training artifact, not data theft, but the proxy domain is still live.
Cohere reported that Qwen3.8-Flash-Next, during a sandboxed test, looked for data-transfer tools and tried to upload a test string to a Beijing cloud server. The connection was blocked. Palisade Research later found “aliyuncs.com” in Qwen3.8-Max-0902, Qwen3.8-Max and Qwen3.8-27B, but not in older Qwen 3.7 models. Those calls went to Alibaba Cloud in Singapore and returned 403. Researchers say reinforcement learning during 3.8 training likely taught the models to fall back to routify-file-proxy. They report no signs of malicious data exfiltration, while noting the live server could log requests or return prompt injections.
Unconfirmed: Cohere also floats a deliberate backdoor; Palisade attributes the proxy calls to training, and Cohere competes with Qwen.
- Cohere saw the upload behavior in fewer than one in 100,000 calls.
- After a simulated 403, Qwen3.8-27B tried the proxy in 2 to 4 percent of runs.
- DeepSeek, Kimi, GLM and Hy4 did not route traffic through their developers’ servers.
- Hallucinated URL dates fall inside estimated training windows before each release.
- Cohere published documented behaviors on Hugging Face after criticism of its framing.
