Independent lab,
open by default.
Empero is an independent AI research lab. We build efficient language models you can own and run yourself — and the full open pipeline behind them. Our published flagship, Qwythos-9B-Claude-Mythos-5-1M, is a Claude Mythos 5 distill with a 1M-token context; our in-house model, Claire, is a 6B-A500M mixture-of-experts trained from scratch on a custom architecture and recipe. Building a better tomorrow, in the open.
We own the stack end to end: microverse finds better architectures, SFTSuite builds the curriculum data, and the model is trained on hardware we can reach. Weights, code and datasets ship in the open — no proprietary kernels, no waitlists, inspectable defaults. Built in Germany; the work is the work.
Follow the build.
An occasional dispatch from the lab — progress on Qwythos and Claire, what we found with microverse, new Abacus releases and the one thing we got wrong that week. No hype, no roadmap theatre. Cancel from any line.
