Qwen3-4B-Instruct-2507-uncensored-v2
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.
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 11x better than an abliterated model)
