This is an uncensored version of
Llama 3.1 70B Instruct created with abliteration (see
this article to know more about it) using
@grimjim's recipe.
I adapted this recipe to Llama 3.1 70B using
failspy/Meta-Llama-3-70B-Instruct-abliterated-v3.5 and optimized the LoRA rank.
The model is fully uncensored in my tests and maintains a high level of quality. A more rigorous evaluation is still needed to measure the impact of this process on benchmarks.
Special thanks to
@grimjim for this technique (see his
8B model) and
@FailSpy for his
70B abliterated model. Please follow them if you're interested in abliterated models.
In addition, thanks to
brev.dev for providing me with compute!
General-purpose, role-play (see feedback from
McUH). Use the Llama 3 chat template.
This model was merged using the
task arithmetic merge method using ./meta-llama/Meta-Llama-3.1-70B-Instruct + Llama-3-70B-Instruct-abliterated-LORA as a base.
