🦙 Llama-3.1-70B-Instruct-lorablated

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.

More precisely, this is a LoRA-abliterated (lorablated) model:

Extraction: We extract a LoRA adapter by comparing two models: a censored Llama 3 and an abliterated Llama 3
Merge: We merge this new LoRA adapter using task arithmetic to a censored Llama 3.1 to abliterate it.

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!

🧩 Configuration

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.

The following YAML configuration was used to produce this model:

base_model: meta-llama/Meta-Llama-3.1-70B-Instruct+Llama-3-70B-Instruct-abliterated-LORA
