Japan's Shizuku AI launches full-duplex Japanese chat model Shizuku-Duplex

Japan-based AI lab Shizuku AI has unveiled Shizuku-Duplex, a full-duplex conversation model. It says this is the second full-duplex model to support smart Japanese conversations after GPT-Live, and it can start thinking without waiting for a full question.

The model has two parts: a front-end for real-time chat and a back-end that handles complex requests in the background, with context compressed every 5 minutes. It runs in 80ms frames and supports three output types: audio, text monologue, and actions.

In Japanese tests, Shizuku-Duplex showed the highest conversation naturalness among 6 models tested, with response quality second only to OpenAI's GPT-Live.

Based on this technology, Shizuku AI is building a companion AI named Shizuku that keeps listening, responds to users' emotions, and honestly shares its own feelings.
