Companies like OpenAI built "Super AI" that threatens human independence. We crave individuality: AI that amplifies, not erases, you.
We’re challenging that with "Second Me": an open-source prototype where you craft your own AI self—a new AI species that preserves you, delivers your context, and defends your interests.
It’s locally trained and hosted—your data, your control—yet globally connected, scaling your intelligence across an AI network. Beyond that, it’s your AI identity interface—a bold standard linking your AI to the world, sparks collaboration among AI selves, and builds tomorrow’s truly native AI apps.
Join us. Tech enthusiasts, AI pros, domain experts—Second Me is your launchpad to extend your mind into the digital horizon.
Train Your AI Self with AI-Native Memory (Paper)
Start training your Second Me today with your own memories! Using Hierarchical Memory Modeling (HMM) and the Me-Alignment Algorithm, your AI self captures your identity, understands your context, and reflects you authentically.
Launch your AI self from your laptop onto our decentralized network—anyone or any app can connect with your permission, sharing your context as your digital identity.
Roleplay: Your AI self switches personas to represent you in different scenarios.
AI Space: Collaborate with other Second Mes to spark ideas or solve problems.
Unlike traditional centralized AI systems, Second Me ensures that your information and intelligence remains local and completely private.
Star and join us, and you will receive all release notifications from GitHub without any delay!

Made with contrib.rocks.
This work leverages the power of the open source community.
For data synthesis, we utilized GraphRAG from Microsoft.
For model deployment, we utilized llama.cpp, which provides efficient inference capabilities.
Our base models primarily come from the Qwen2.5 series.
We also want to extend our sincere gratitude to all users who have experienced Second Me. We recognize that there is significant room for optimization throughout the entire pipeline, and we are fully committed to iterative improvements to ensure everyone can enjoy the best possible experience locally.
