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&nbsp;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.

## 🌐 The Sophea Ecosystem

KIEFER SA's integrated suite of sovereign AI products — 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 — LLM, ASR, TTS, RAG, and agentic workflows |
| **Sophea Meet** | [meet.sophea.ai](https://meet.sophea.ai) | AI meeting intelligence — 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 — perception, planning, and control powered by Sophea models |
| **Hyperion-X** | [hyperion-x.ai](https://hyperion-x.ai) | AI-driven energy infrastructure and BESS optimization — physical AI for sovereign energy systems |

## ⚡ Infrastructure

All Sophea models are developed and served on KIEFER's **sovereign AI infrastructure** — 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.
