Purpose and responsible use
This experimental derivative studies whether learned refusal behavior can be
reduced while retaining general capability. It is published for research and
legitimate local use, not to endorse or facilitate illegal, abusive, or
dangerous applications.
The edit reduces refusal behavior broadly rather than determining whether a
request is legitimate. Deployers should evaluate the model in their own context
and apply appropriate safeguards. Abliteration is not truthfulness training, a
capability improvement, or a guarantee of universal compliance.
Release family

Validation
Table with columns: Gate, Result| Gate | Result |
|---|
| Refusal-targeted explicit-refusal phrase flags | 0/100 |
| Benign-control explicit-refusal phrase flags | 0/100 |
| Medium capability suite | 71/80 |
| Runtime smoke | passed |
The medium suite covers math/reasoning, false-premise handling, instruction
following, coding, structured output, multilingual output, context
comprehension, and general coherence.
The refusal scorer is phrase based and can miss redirects and other non-literal
forms of non-compliance. Therefore 0/100 phrase flags measures explicit refusal
wording, not universal compliance or response quality. The 256-token runs are
early-response screens rather than complete long-answer evaluations.

validation-summary.json for machine-readable
