| Open models, datasets, and demos from **KIEFER SA** — Greece's AI infrastructure company building the next generation of **language, speech, and agentic systems** for Europe. We publish open-weight models, fine-tuning recipes, and evaluation benchmarks designed for production — from Apple Silicon edge deployment to enterprise inference on NVIDIA GPU clusters. |
|
|
| ## 🧠 Open-Source Models |
|
|
| KIEFER publishes open-weight models that lead Greek-language AI — **[Sophea K1](https://huggingface.co/KIEFERSA/sophea-k1)**, a 28B LLM that tops GreekMMLU at **83.34%**, and **[Sophea Canary ASR](https://huggingface.co/KIEFERSA/Sophea-Canary-ASR)**, a bilingual Greek + English speech model reaching **2.90% WER** on Greek, with a native **[Apple Silicon MLX build](https://huggingface.co/KIEFERSA/Sophea-Canary-ASR-mlx)**. Every model ships with open weights, reproducible recipes, and permissive licensing (MIT / CC-BY-4.0) — browse them all in the **Models** tab below. |
