PewDiePie unveiled Ajax on October 2, an uncensored AI model with 9 billion parameters designed to run on home PCs through his Odysseus workspace. OpenAI banned his account twice during development after detecting distillation, where outputs from one model train another.
Ajax is fine-tuned from Alibaba’s Qwen3.5-9B and functions as an autonomous agent within Odysseus. It handles daily tasks including web search, email management, calendar scheduling, and to-do organization. PewDiePie launched Odysseus in May 2026 as a free, open-source, self-hosted alternative to ChatGPT. The workspace stores all conversations locally on user hardware rather than cloud servers.
OpenAI’s first ban cited distillation explicitly. PewDiePie eventually got his account reinstated, but a second ban followed when he “ran the model again to create my seed data.” Distillation violates OpenAI’s terms of service because it uses proprietary model outputs as training data for competing products. The bans highlight growing tension between large AI companies protecting their models and independent developers building alternatives.
To remove safety refusals from Ajax, PewDiePie used an open-source tool called Heretic that identifies and strips refused prompts from the model’s behavior. He acknowledged the trade-off directly: “Fewer guardrails also mean more room for misuse.” However, he maintained that Ajax retains restrictions against “harming other people or oneself” and is “not designed to provide dangerous actionable instructions.”
Early testing showed roughly 90% task completion rates, though PewDiePie described Ajax as a work in progress. His development setup includes 10 GPUs with eight modified RTX 4090 cards carrying 48 GB memory each. Despite this high-end infrastructure behind development, Ajax targets standard home PCs for end-user deployment.
The model weights remain private as of launch. The download link currently directs users to a data contribution page rather than the model itself. The Odysseus workspace operates under an AGPL-3.0-or-later open-source license and remains free to use.
Ajax joins a growing category of locally deployable AI models that prioritize user privacy and reduced censorship over cloud-based convenience. Meta’s Llama, Mistral, and Alibaba’s Qwen family already serve this market. PewDiePie’s entry differs primarily through his creator’s massive audience reach. With over 110 million YouTube subscribers, his promotion of local AI deployment introduces self-hosted models to a mainstream consumer audience that enterprise-focused open-source projects typically miss.
