Open models, datasets, and demos from **KIEFER SA** โ€” 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 โ€” from Apple Silicon edge deployment to enterprise inference on NVIDIA GPU clusters. ## ๐Ÿง  Open-Source Models KIEFER publishes open-weight models that lead Greek-language AI โ€” **[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) โ€” browse them all in the **Models** tab below. ## ๐ŸŒ The Sophea Ecosystem KIEFER SA's integrated suite of sovereign AI products โ€” language models, speech intelligence, robotics, and energy infrastructure. Every product is built on open-weight Sophea models and served on KIEFER's sovereign European GPU infrastructure. | Product | URL | Description | |---|---|---| | **Sophea AI** | [sophea.ai](https://sophea.ai) | The core platform โ€” LLM, ASR, TTS, RAG, and agentic workflows | | **Sophea Meet** | [meet.sophea.ai](https://meet.sophea.ai) | AI meeting intelligence โ€” real-time transcription, summaries, and action items powered by Sophea ASR + K1 | | **Sophea Nous** | [nous.sophea.ai](https://nous.sophea.ai) | Advanced reasoning and knowledge platform built on Sophea K1 and GraphRAG | | **AI Robots** | [ai-robots.ai](https://ai-robots.ai) | Humanoid and quadruped robotics AI โ€” perception, planning, and control powered by Sophea models | | **Hyperion-X** | [hyperion-x.ai](https://hyperion-x.ai) | AI-driven energy infrastructure and BESS optimization โ€” physical AI for sovereign energy systems | ## โšก Infrastructure All Sophea models are developed and served on KIEFER's **sovereign AI infrastructure** โ€” NVIDIA GPU clusters deployed in Greece, designed for data-residency compliance and low-latency European inference. Our roadmap targets **1,000+ GPU capacity** to support the full Sophea model family at enterprise scale. ## ๐Ÿ“Ž Resources - ๐ŸŒ **Website** โ€” [kiefer.gr](https://kiefer.gr) - ๐Ÿฆ‰ **Try Sophea K1** โ€” [sophea.ai](https://sophea.ai) - ๐Ÿ“„ **Licenses** โ€” MIT (Sophea K1) ยท CC-BY-4.0 (Sophea ASR models) - ๐Ÿค **Enterprise & partnerships** โ€” [info@kiefer.gr](mailto:info@kiefer.gr) ยท [info@sophea.ai](mailto:info@sophea.ai) --- ![Building Sovereign European AI โ€” from Athens to Europe ยท by KIEFER SA](./tagline.png)
