Sophea-Titan-1: Greek Multimodal Chat Model
Sophea-Titan-1 is a 27 billion parameter multimodal chat model developed by Kiefer SA, built upon the Qwen3.6-27B architecture. It has been specifically fine-tuned for Greek language conversational tasks, incorporating register control and a fixed assistant identity. Notably, it maintains strong English language proficiency and multimodal vision capabilities.
Key Capabilities
- Primary Language Focus: Optimized for general-purpose Greek conversation and Greek-knowledge question answering.
- Multimodal: Retains the vision capabilities of its base model, Qwen3.6-27B.
- Register Control: Offers the ability to switch between formal and informal conversational styles.
- Performance: Achieves the strongest general Greek benchmark scores among comparable open models, outperforming its base model and other Greek LLMs like Krikri-8B. It also demonstrates excellent English retention and strong vision performance on MMStar benchmarks.
- Efficiency: When run in "non-thinking" mode (recommended), it provides high-quality Greek output and can approach the performance of much larger frontier MoE models in Greek benchmarks.
Good For
- Developers building Greek-centric conversational AI applications.
- Applications requiring multimodal understanding in Greek.
- Use cases where controlled conversational register is beneficial.
It is important to note that for optimal Greek output quality, the model should be served with enable_thinking=false in the chat template. The model is not evaluated for safety-critical or legal/medical decisions.
