*2 Since there was no mention of these template versions in rinna's LM Benchmark, the scores were calculated without specifying a template.

🧩 Configuration

The model has been made with a custom version of the mergekit library (mixtral branch) and the following configuration:

base_model: rinna/youri-7b-chat
gate_mode: hidden # one of "hidden", "cheap_embed", or "random"
dtype: bfloat16 # output dtype (float32, float16, or bfloat16)
experts:
  - source_model: rinna/youri-7b-chat
    positive_prompts: 
      - "質問と回答の選択肢を入力として受け取り、選択肢から回答を選択してください。"
      - "前提と仮説の関係を含意、矛盾、中立の中から回答してください。"
      - "以下のテキストを、ポジティブまたはネガティブの感情クラスのいずれかに分類してください。"
      - "与えられた問題に対して、ステップごとに答えを導き出してください。"
  - source_model: rinna/youri-7b-instruction
    positive_prompts: 
     - "質問に対する回答を題名と文章から一言で抽出してください。回答は名詞で答えてください。"
     - "与えられたニュース記事を要約してください。"
     - "与えられた文が文法的であるかを回答してください。"

The positive_prompts in the above configuration are extracted from the instructions of benchmarks that each model excels in. For reference on the benchmarks for each model, please see the LM Benchmark at rinna's LM Benchmark. These benchmarks provide a detailed overview of the areas where each individual model performs particularly well, guiding the effective use of the merged model in various natural language processing tasks.
