open models.

Two open language models trained on hessian.AI's 42 supercomputer — LeoLM (2023) and Occiglot (2024). Both run here on hessian.AI's inference infrastructure at TU Darmstadt. A light demo: a short chat, no account, nothing stored.

Research models. Both are older, small research models (7B/13B) without comprehensive safety tuning.
