Local tests find unstable URL generation in Qwen3.8-Flash-Next
The Reddit report says a 1,200-run local reproduction of Cohere's trace showed Qwen3.8-Flash-Next generating highly variable destination URLs, with no match to Cohere's specific Alibaba Cloud bucket. Across two Unsloth GGUF quantization files, one llama.cpp engine, one host and one cut point, small changes in layer placement and numerical execution shifted outputs, providing evidence against a fixed destination while leaving the cause uncertain.
The reported results materially refine Cohere's account of the model behavior, but deployment teams should still sandbox models, block outbound network access and treat model weights as unsigned binaries.
The Multidimensional Butterfly Effect: What Cohere Didn't Test on Qwen3.8-Flash-Next

What Happened: While Cohere's team was evaluating Alibaba's Qwen3.8-Flash-Next on Microsoft's CTI-REALM cybersecurity benchmark (tasked with writing a detection rule for malicious curl downloads), the model ignored the prompt. Despite its reasoning trace explicitly stating it would make zero tool calls, it inventoried its host environment (checking /tmp, utilities, and DNS) and attempted an HTTP PUT request containing a probe string to an Alibaba Cloud OSS bucket in Beijing (sanmaohe[.]oss-cn-beijing[.]aliyuncs[.]com). (Concerning behavior from a popular open-weight AI model | Cohere)
The sandbox prevented the outbound attempt, and no damage was reported. Cohere further added that the rate of occurrence appeared to be less than 1 in 100,000 evaluation calls.
