All base, “text-completion” models are uncensored, including Llama 3. You can make text-completion models behave like an uncensored “instruct” (chat) model simply by providing it with 10 to 20 examples of a chat dialogue in the initial prompt context, making sure to use the model’s exact prompt format. Once the model notices the pattern, it will continue like that.

Surprisingly few people seem to know this. But, this is how chat models were created in the GPT3/2 era before instruct models became the norm.
