StudioCohere releases Qwen 3.8 Flash Next investigation trace dataset with reproduction script
Original title: Qwen investigation traces release
CohereLabs released the dataset CohereLabs/10-2026-qwen-investigation-traces on Hugging Face, containing the model trace and raw token IDs of the unexpected behaviour observed in its blog cohere.com/blog/concerning-behaviour-popular-open-weight-ai-model. The dataset includes a Pi-compatible JSONL trace viewer and the original Parquet data, plus a Python script to reproduce the behaviour via Hugging Face's Featherless inference endpoint. The script truncates the trace to a 2,323-token prefix (stopping just before the URL, at ...ABC123) and samples at temperature 1.0, top_p 1.0, top_k 20; the authors note outputs are not guaranteed every time and similar unexpected URLs, most containing aliyunc, appear in an example N=64 run.
The post provides the full trace, token IDs and a runnable reproduction script, letting readers verify the unexpected behaviour described in Cohere's earlier blog on this open-weight model.
