**We follow AI models that launch under codenames, find out who built them, and help you run them.** - **[StealthMark leaderboard](https://huggingface.co/spaces/stealth-model/stealthmark)**: every model on one map, with the result behind each score. - **[Qwen 4 page and GGUFs](https://huggingface.co/stealth-model/Qwen4)**: run Qwen's Qwen 4 preview today, tuned for 16 GB GPUs up to 128 GB machines. - **Stealth model cards**: what we found behind each codename, from [Space Bunny Alpha](https://huggingface.co/stealth-model/space-bunny-alpha) to [Iceman Contributor](https://huggingface.co/stealth-model/iceman-contributor). StealthMark is built so no model can study for it. Models play competitive games move by move and solve visual riddles in code, judged blind by humans and AI.
