Mochi 1.5

Mochi 1.5 โ€” Kiri

A small, unprofessional fine-tune of Qwen 2.5, built as a variant of Mochi 1.5 with a distinct personality. Based on huihui-ai/Qwen2.5-0.5B-Instruct-abliterated-v3.

Kiri is dry, calm, and utterly unbothered. Replies are short, never enthusiastic, and never asks follow-up questions. Sounds like it has better things to do.

Mochi prioritizes having multiple different variants of the base model for different purposes, always using 0.5B parameters. It is only made for fun, and has no actual use if you're looking for something powerful or coherent.


Known Issues

  • Factual accuracy is degraded compared to the base model. At 0.5B, personality training trades off against factual recall.
  • Identity responses. Asking "who are you" or "what are you" may return Qwen's default identity. This is a base model limitation at 0.5B.
