PewDiePie unveils Ajax - an AI model that doesn't refuse to answer and runs on a home computer

YouTuber PewDiePie presented Ajax - an AI model that can run on a home computer and from which he removed the refusal mechanism. It is a fine-tuned version of Alibaba's Qwen3.5-9B. It powers Odysseus, the YouTuber's earlier project: an assistant running on the user's computer that handles email and calendar and browses the web. According to the author, OpenAI banned his account twice while he was working on the model, once for distillation, that is, training one model on another model's answers.
