**Lythri** builds small language models for **emotional companionship** that run entirely on your own device.
The models are chat-focus and go through a full life loop from CPT to GRPO using gemma4-PT framework, using special data generation pipeline as well as the novel reward system, which leads a decent result againt original instruct models
**The whole training process is self-funded. If you like our model, please click a free like — that means a lot to me!**
