  "transcript": "Soooo! Since Anthropic share their [Jacobian-Lens](https://github.com/anthropics/jacobian-lens) a few days ago I went on and made a tool based on it which _adds_ the possibilité to export a model which will have the same behavior after tweaking it's J-Space.\n\nThis means manually alter the behavior and abliterate by using a human brain.\n\nI'm still working on it but couldn't wait to produce something first.\n\nSO After finally getting a working codebase I immediatly jumped and tried to make pretty pervy model PURELY in the name of science.\n\n# Let me introduce you to [Nikusui-v1](https://huggingface.co/extraltodeus/Qwen3.5-9B-Nikusui-v1) the first of it's kind !\n\n[And a couple gguf quants](https://huggingface.co/extraltodeus/Qwen3.5-9B-Nikusui-v1-gguf)\n\nI'd be delighted to get some feedback :D\n\n\n\n--- Top Comments ---\n\n\n[1 upvotes] Your post is getting popular and we just featured it on our Discord!
