Gemini Advanced が 3.1 Pro にアップデートされてから、どうにも動作が遅い。

昨年まではChatGPTの課金ユーザーだった。
でも、GWSとの連携やNano Banana、NotebookLM、それに2TBのGoogle Driveまでついてくる包括的なパッケージに魅力を感じて、Geminiに乗り換えた。
ChatGPT特有の「寄り添ってくる感じ」があまり好きじゃなかったのもあるし、業務でもGeminiを使い始めたので、学習も兼ねてのことだった。

Gemini 3 Proのころはとても快適だった。
自分用のアシスタントGemを作って、毎日のスケジュールやTODOを処理させるのがすごく便利だったからだ。
時々「TODOやKeepの作成は学習中でできません」とポンコツな嘘をついてくることもあったが、タスクのカテゴリ管理や統一タグの付与とか、人間が手作業でやるとだんだん雑になっていくような作業は、Geminiを介した方がずっと楽にキープできた。

そんな中、Gemini 3.1 Proが導入された途端、パフォーマンスが目に見えて劣化した。
モデル切り替え後の一時的な事象だと思っていたが、この記事を書いている今も継続的に発生している。
もちろん、大規模なモデル入れ替えに伴う一時的な不安定さは許容すべきだとは思っている。モデル更新による恩恵の方が大きいのは自明だからだ。

しかし、リリースからこれだけ経過しても改善が見られないのは、いち課金ユーザーとしてはシンプルに悲しい。
会話をするたびに、文章自体は最後まで生成されているのに、ずっとプロセスが実行中のように回っていて次の会話に進めない。このリズムの悪さは致命的だ。
世界的にも指摘されている現象らしいので改善はされるのだろうが、果たしていつになるのか。

そんなフラストレーションもあって、試験的に Claude Sonnet 4.6 での会話も始めてみた。
それぞれのAIモデルには特徴があるが、デフォルトの素の状態で話していて、一番しっくりくるのはClaudeな気がしている。

事実ベースで話してくれる安心感と、「わからないことはわからない」とちゃんと言えること。
ツールを仕事の相棒として信頼していく上で、この姿勢はとても大切だと思った。

この記事を書きながらふと思ったが、これって現実の人間世界でも同じだな。
調子が悪いなら悪いと、わからないならわからないと正直に言う。
AIも人も、結局は「誠実であるか」が一番大事なのかもしれない。

24:Ta2f,

Ever since Gemini Advanced was updated to 3.1 Pro, it has been noticeably slow.

Until last year, I was a paying user of ChatGPT.
However, I switched to Gemini because I found the comprehensive package appealing, including integration with Workspace, Nano Banana, NotebookLM, and 2TB of Google Drive storage.
Part of the reason was that I didn't really like the "overly empathetic" vibe of ChatGPT, and since we started using Gemini in my day job, it also served as a learning opportunity.

During the Gemini 3 Pro era, it was very comfortable to use.
Creating a personal assistant Gem to handle my daily schedules and to-dos was incredibly convenient.
Occasionally, it would tell silly lies like "I'm still learning and cannot create to-dos or Keep notes," but managing task categories and applying consistent tags—things that tend to get sloppy over time when a human does them manually—was much easier to maintain through Gemini.

However, the moment Gemini 3.1 Pro was introduced, the performance visibly deteriorated.
I thought it was just a temporary issue following the model switch, but it's still consistently happening even now as I write this article.
Of course, I believe that temporary instability caused by an extensive model replacement should be tolerated. It's self-evident that the benefits of updating the model outweigh the drawbacks.

Still, as a paying user, it's simply sad to see no improvement after so much time has passed since the release.
Every time I have a conversation, even after the text generation is fully complete, the process seems to keep spinning, preventing me from moving on to the next prompt. This poor rhythm is fatal.
It seems to be a globally reported issue, so I assume it will be fixed eventually, but I wonder when that will be.

Partly out of that frustration, I also started experimenting with conversations on Claude Sonnet 4.6.
While each AI model has its characteristics, speaking with Claude in its default, vanilla state feels the most natural to me.

The sense of security from its fact-based responses and its ability to properly admit when it "doesn't know something that it doesn't know."
I realized that this attitude is crucial when trusting a tool as a partner in work.

While writing this article, it suddenly occurred to me that this is true in the real human world as well.
If you're in a bad condition, say so; if you don't know something, honestly say you don't know.
Perhaps in the end, whether it's an AI or a person, being "honest" is what matters most.
