PewDiePie introduces Ajax, a home-PC AI assistant still awaiting a public download

PewDiePie has shown off an AI assistant intended to handle everyday work on a home PC, rather than depend entirely on cloud services. Called Ajax, it is built for his self-hosted Odysseus workspace. The unveiling comes with two important qualifications: a public download was still pending, and the creator says OpenAI suspended his account twice while he was developing it.

Training data became a point of conflict

Felix Kjellberg, better known as PewDiePie, said he wanted to improve Ajax through distillation: using another model’s outputs to train his own. Tom’s Hardware reported that an OpenAI email displayed in his video explicitly cited distillation as the reason for one account deactivation.

Kjellberg said OpenAI reinstated his account once. A second suspension came after he tried to generate what he called seed data, or initial training material for Ajax. The email he showed gave no specific examples. OpenAI has not publicly explained either action, so details rest on Kjellberg’s account and the displayed email.

The technique and the permission to use it are separate issues. Interesting Engineering notes that OpenAI describes distillation as a legitimate way to create training data for smaller models. It also reports that OpenAI’s terms prohibit using its outputs to develop competing models and automatically or programmatically extracting outputs.

A smaller assistant with fewer refusals

Ajax is a fine-tuned version of Alibaba’s Qwen3.5-9B, a model with around 9 billion parameters. Kjellberg argues that everyday tasks do not require an enormous model. His approach is to train a smaller one specifically for Odysseus, the software environment in which it will use tools.

The project describes Ajax as an always-on assistant for searches, web browsing, email and calendars, with processing intended to stay private on the user’s hardware. Those are intended functions and a privacy promise, not independently demonstrated results.

Kjellberg calls Ajax “uncensored.” He said he used the open-source Heretic tool to remove refusal behavior without substantially harming other capabilities. Still, he says Ajax is not meant to help with requests involving harm to oneself or others. On legal advice, it is not designed to provide dangerous, actionable instructions. Those safeguards have not been independently evaluated.

The next version still needs finishing

As of October 2, Ajax’s website still said “Coming soon.” Final hardware requirements, a confirmed license for its model weights—the files needed to run it—and independent benchmark results were unavailable. The home-PC pitch therefore does not yet tell prospective users which computers can support it.

Kjellberg said he planned more reinforcement learning, another refusal-removal pass, quantization to reduce the model’s storage and memory needs, and benchmarking. He also said another version of Ajax and Odysseus was planned, without specifying a release date.
