Out of the box, open-weight models have guardrails similar to the rest. But unlike the closed models they can be 'abliterated' with varying degrees of success. If you run an aggressive Heretic abliteration of Qwen 3.6 27B you will not generally experience either refusals or an obvious degradation in quality.
I personally like the https://huggingface.co/HauhauCS version of Qwen 27B from a purely subjective point of view as a user, but that particular one has come under criticism for reasons that don't necessarily affect its quality or usability.
Some of the larger models have also undergone similar treatment, but it's less common.
