`rinna/youri-7b-chat`

Overview

The model is the instruction-tuned version of rinna/youri-7b. It adopts a chat-style input format.

Model architecture

A 32-layer, 4096-hidden-size transformer-based language model. Refer to the llama2 paper for architecture details.
Fine-tuning

The fine-tuning data is the subset of the following datasets.
- Databricks Dolly data
- Japanese Databricks Dolly data
- Anthropic HH RLHF data and its Japanese translation
- FLAN Instruction Tuning data and its Japanese translation
- Izumi lab LLM Japanese dataset
  - The following sections are used
    - alt
    - aozora-txt
    - CourseraParallel
    - ParaNatCom
    - Tab-delimited_Bilingual_Sentence_Pairs
    - tanaka-corpus
    - wikinews
    - wordnet
    - yasashi-japanese
  - The remaining sections contain commonly used evaluation corpora so they are skipped to prevent data leak.
