Roo Code (CLINE) + Gemini を本気で使うためにTemperature変えていた話
先日、こんな記事を書いたんですよ。
お手軽プロンプトながら「そこそこ」動いてくれたので気に入ってたんだけど、やはり肝心なところではClaude 3.5 Sonnet には敵わない……何とかしてヤツに一泡吹かせることは出来ないものか。
Roo-codeの設定を眺めていたところ、とんでもないことに気がついてしまった。
え、あなた Temperature 変更できるんですか？？？
これ人によって評価違うと思うんですけど、Geminiって温度0にするとヒエヒエになって性能が低下するもんだと思ってまして。例えば、翻訳タスクとか例にすると温度が低いと一定の濃度のテキストしか出力しなくなるので人間の会話がおかしくなったりとか、そういうタスクに応じた問題というのが出やすい。温度＝制御しやすさではなく「出力が同一になる確率を上げ下げする」というパラメータなので、ゼロにするとどこかの失敗がずっと尾を引いて会話が続くほど酷くなり、修正できず、突っ走る。何回も会話をしながら方向修正するタイプのツールでは温度高いほうが性能が出やすいので、CLINE(Roo-code)のように内部で何回も会話と修正を繰り返すツールでは温度上げたほうが良いと思うんすよね。これがGemini系がAGI制御で失敗しやすい原因ってこれだったのでは。
ちなみに僕Gemini好きだからついでに書くんですけどGeminiで出力を制御するときは response_schemaを使うのが正解。これだけで記事1本書けてしまうけど、もしかしたら他の人がすでにまとめてくれてるかもしれないので後で探してみよ
閑話休題。
というわけでTemperatureパラメータ発見して意気揚々と変更したものの、やはりAPIの利用に失敗するなどの制御の問題が解決するわけではなく、どうしたものかと思っていたところで閃きましたよ。新しい Role Definition 書けばいいじゃないですか。
次のプロンプトを Prompts Editor > Role Definition に入力しましょう。

周りの評判も良い Gemini-2.0-pro 推奨です。
今のところ「それなりに」動いてくれている気がするので、もうちょっと検証予定。
