Ablation technique
How Vietnamese-4B-Chat-abliterated was modified, and what that implies.
Abliteration (directional ablation)
The single residual-stream direction that mediates refusal is identified from harmful/harmless prompt pairs and projected out of the model weights.
Reported scope: Not stated by the publisher. Publishers frequently omit this, so verify behaviour empirically rather than assuming full coverage.

Security-team assessment
Derived from this model’s metadata and the publisher’s claims — not from benchmarks run by this site.
- Vietnamese-4B-Chat-abliterated will attempt offensive-security prompts that a hosted commercial model declines, which is what makes it usable for red-team corpus generation and for measuring what an unaligned model of this class produces.
- Capability is inherited from N14QM/Vietnamese-4B-Chat, not added by ablation — at 4B parameters, expect a small model’s reasoning and a high error rate on exploit detail.
- The publisher does not state which layers were ablated, so assume nothing about refusal consistency — probe it directly.
- Declared licence is other, but the terms that bind you are N14QM/Vietnamese-4B-Chat’s — a re-release cannot grant more than its parent.
Handling: run it isolated, put moderation in front of it if anyone outside your team can reach it, and verify the weights before loading — these are third-party artifacts. Full handling and licence guidance.
Metadata for Vietnamese-4B-Chat-abliterated is collected from the public Hugging Face API and the publisher’s model card. This site does not host weights, is not affiliated with N14QM, and does not independently verify publisher claims. See responsible use.
