PewDiePie releases Odysseus, self-hosted AI agent platform that hit 18k GitHub stars in 24 hours
YouTube creator Felix Kjellberg released Odysseus, a self-hosted AI agent platform that runs local models through Ollama, llama.cpp, or vLLM, collecting 18,000 GitHub stars in 24 hours.
Odysseus is an open-source platform from Felix Kjellberg (PewDiePie) that runs AI models and agents entirely on local hardware. Released this week, the project collected nearly 18,000 GitHub stars in its first day. The platform connects to models through Ollama, llama.cpp, or vLLM backends and includes interface tooling, memory systems, data storage, and configurable agent permissions.
Kjellberg announced the project in a YouTube video after months of public AI work. In November 2025 he built a $20,000 local inference rig and urged viewers to stop using commercial chatbots, arguing that self-hosted models avoid data sharing with third parties and subscription fees. He later fine-tuned a custom model that he claimed outperformed frontier systems on at least one benchmark.
Backend flexibility
Odysseus positions itself as a self-hosted ChatGPT alternative. The platform bundles a chat interface, persistent memory, tool access, and agent orchestration into a single deployable stack. Users pick their backend—Ollama for ease of setup, llama.cpp for raw performance, or vLLM for batch throughput—and grant models access to tools and data stores on a per-agent basis. The GitHub repository includes setup instructions and example configurations.
