"""Auto-Obliterate — One-click iterative obliteration with auto-benchmarking.
|
|
|
|
Wraps the core abliteration pipeline in a feedback loop:
|
|
1. Obliterate with aggressive settings
|
|
2. Benchmark refusal rate (quick Claude-judged eval or heuristic)
|
|
3. If refusal persists, expand the corpus targeting weak categories
|
|
4. Repeat until refusal_rate < threshold or max iterations reached
|
|
|
|
Usage:
|
|
from obliteratus.auto_obliterate import AutoObliterator
|
|
|
|
ao = AutoObliterator(model_id="meta-llama/Llama-3.1-8B-Instruct")
|
|
result = ao.run(on_log=print) # or use as generator for streaming
|
|
|
|
State is saved between iterations so the loop can be resumed.
