PewDiePie’s Ajax AI Model: How It Works, Its Limits and the OpenAI Ban Claims

PewDiePie’s Ajax is a fine-tuned Qwen 3.5 model with roughly 9 billion parameters, built for use in his self-hosted Odysseus workspace. It is designed to run locally and help with everyday assistant tasks. But details such as its real-world performance, safety and public availability remain uncertain in the reporting reviewed. 612

What Ajax is designed to do

Ajax is a fine-tune of an existing model, rather than a model trained from scratch. PewDiePie describes it as an assistant for tasks including web search and browsing, email, calendars and to-do lists, used through Odysseus. 6912

Running a model locally is intended to let the assistant operate on a user’s own computer rather than rely on a hosted model for every interaction. However, the available reporting does not establish Ajax’s hardware requirements or independently verify how its local setup handles user data. 912

What “uncensored” means—and what it doesn’t

Ajax has been described as “uncensored” because its refusal behavior was deliberately reduced. That label describes a change in how often the model refuses requests; it is not evidence that the model is accurate, secure or safe to use without safeguards. Independent safety results were not available in the reporting reviewed. 912

What PewDiePie says happened with OpenAI’s Sol

PewDiePie says OpenAI suspended his account twice during Ajax’s development. He described an initial suspension as unjustified and says it was reversed after an appeal. He says another suspension came after he used outputs from OpenAI’s Sol model to generate training data for Ajax. 34

An email shown in his video reportedly cited “distillation”—using one model’s outputs to train another—as a reason for a suspension. The precise sequence and causes of the suspensions have not been publicly confirmed by OpenAI, so the details remain his account rather than an independently established explanation. 715

What remains unclear about Ajax’s release

Reports describe Ajax as unveiled or released, but they do not consistently establish that its model weights were publicly available to download. One report said the linked page was collecting Odysseus training data rather than distributing Ajax weights; hardware guidance and independent safety tests were also not available there. 2612

The practical takeaway is that Ajax has been presented as a local assistant, not yet as a model whose public availability, hardware needs or safety have been demonstrated for independent review. Those details matter more than the “uncensored” label when deciding whether it is ready for everyday use. 612
