Kroonen AI
Kroonen AI is an independent research lab and product studio. We study language models end to end, from pretraining on our own hardware to interpretability on open frontier-scale models, and we release the weights, code and write-ups, including what didn't work.
Research
Glimmer Scope (November 2026). Sparse autoencoders on nine layers of Muse Glimmer 30B: 519,383 labeled features, more than 170,000 steering tests, and every feature followed from layer to layer. SAEs · Live demo · Atlas · Report
Genesis 1B. A 1B-parameter foundation model pretrained from scratch on two RTX 4090s: 80,000 steps, about 42B tokens. Playground
Focus
- Interpretability and steering of open models
- Pretraining and fine-tuning on modest hardware
- Evaluation and model safety
- Local-first and hybrid deployment
