20/2/2026

Googleは、2026年2月19日にGemini 3.1 Proを発表しました。本モデルは、未知の課題への適応力を示す「ARC-AGI-2」ベンチマークで77.1%という高得点を記録し、競合他社と比較した際の圧倒的なコストパフォーマンスを示しています。
2026年2月12日に発表された特殊推論モード「Gemini 3 Deep Think」(「ARC-AGI-2」ベンチマークで84.6%、高価格帯ユーザーしか使えない)とは、異なるアプローチに基づくシステムで、Gemini 3.1 Proは前モデルであるGemini 3.0 Proと同一の価格設定を維持しながらその実質的な能力は世代交代レベルの飛躍を遂げているということです。
Gemini 3.1 Proについて、生成AIに深掘りさせました。さらに、結果をNotebookLMでインフォグラフィック、スライド資料にさせました。
なお、生成AIによる調査・分析結果は、公開された情報からだけの分析であり、必ずしも実情を示したものではないこと、誤った情報も含まれていることについてはご留意されたうえで、ご参照ください。

February 20 – Gemini 3.1 Pro Achieves 77.1% on “ARC-AGI-2”
On February 19, 2026, Google announced Gemini 3.1 Pro. The model achieved a high score of 77.1% on the “ARC-AGI-2” benchmark, which measures adaptability to novel tasks, demonstrating outstanding cost performance compared with competing models.
Unlike the specialized reasoning mode “Gemini 3 Deep Think,” announced on February 12, 2026 (which scored 84.6% on ARC-AGI-2 but is available only to high-priced-tier users), Gemini 3.1 Pro is based on a different architectural approach. Notably, while maintaining the same pricing as its predecessor, Gemini 3.0 Pro, Gemini 3.1 Pro is said to deliver a generational leap in practical capability.
I asked generative AI to conduct an in-depth analysis of Gemini 3.1 Pro. Furthermore, the results were transformed into infographics and slide materials using NotebookLM.
Please note that the research and analysis conducted by generative AI are based solely on publicly available information and may not necessarily reflect actual conditions. The results may also contain inaccuracies. I kindly ask that you review the material with this understanding.
