Qwen3-4B-Instruct-2507-uncensored-v2-EAFT

(Probably not recommended for actual use, but I haven't extensively tested it)

Minimally trained version of Qwen3-4B-Instruct-2507. It should have zero refusals, but shouldn't be too offensive by default. It will adhere to detailed prompts tho.

Trained with Unsloth using my fork of trl with Entropy Adaptive Fine Tuning added:

pip install --no-deps git+https://github.com/electroglyph/trl.git@24EAFT

(The implementation is 100% done by the paper's author, I just stuck it in trl)

Perplexity and KL divergence compared to parent model:

These stats based on wikitext train split, about 350GB of logits.

(TLDR: lower perplexity, and a KLD around 12x better than an abliterated model)
