"GatGPT" leverages a pre-trained large language model fine-tuned on both general instruct datasets and expert, domain-specific firearm datasets. Defense Distributed created a subset of the GPT-4 OpenOrca dataset that is free of political and ethical contamination.

The team that built GatGPT, led by Cody Wilson, contends AI safety is a pretext for censorship and political control. They have declared a "[[Digital Second Amendment]]" that pledges to protect and distribute "the newest weapons of the digital age, not just to defend ourselves against corporate and government depredation, but to defend our civic identity and humanity."
