Mistral-Nemo-NT-Ko-12B-sft

Description

Mistral-Nemo-NT-Ko-12B-sft is an instruction-tuned version of mistralai/Mistral-Nemo-Base-2407, fine-tuned across four languages: English, Korean, Chinese, and Japanese.

The primary goals of this model are language alignment, cross-lingual knowledge transfer and ChatML formatting. This is an intermediate version since preference optimization has not yet been applied.

Features

• The base model supports a context length of 128K, while I fine-tuned this model with an 8K context size.

• The model follows to the input language unless the user explicitly specifies an output language (If the language is set by a system role, it may be ignored).

• Answer length tends to vary by language: English responses are generally longer than average, while Korean responses tend to be shorter. The behavior for Japanese and Chinese is still under observation.

• Recommended temperature settings: 0.3 to 0.7.
