6つの「Deep Research」を比較

21/2/2025

0 Comments

 
xAIが「地球上で最も賢いAI」として2月18日にリリースしたばかりの「Grok 3」が無料開放されました。2月20日時点で、Xユーザーであれば有料プランに加入していなくても、高度な推論機能やDeepSearchを24時間に2回まで利用できるようです。(2月18日時点では、Xの有料プラン「プレミアムプラス」ユーザーに対し一部機能を、Grokの機能を単体で提供する「SuperGrok」ユーザーに全機能を提供していて、無料では使えませんでした。)
さっそく、Grok 3 Deep Searchを使ってみました。OpenAI Deep Research、Gemini Deep Research、Genspark Deep Research、Felo AI Deep Research、Perplexity Deep Researchにも同じプロンプトで指示しました。(題材は、セルロースナノファイバー)
6つの「Deep Research」を比較したことになりますが、比較検討はご自身で行ってください。

Comparison of Six “Deep Research” Tools
 
xAI’s “Grok 3,” which was just released on February 18 as “the smartest AI on Earth,” has been made available for free. As of February 20, even X users who are not subscribed to a paid plan can use advanced reasoning capabilities and DeepSearch up to twice within a 24-hour period. (On February 18, some functions were provided only to X’s paid “Premium Plus” users, and full functionalities were available only to “SuperGrok” users—who received Grok’s capabilities as a standalone product—so it was not free.)
I immediately tried using Grok 3 Deep Search. I also provided the same prompt to OpenAI Deep Research, Gemini Deep Research, Genspark Deep Research, Felo AI Deep Research, and Perplexity Deep Research. (The subject is cellulose nanofibers.)
This constitutes a comparison of six “Deep Research” tools; however, please conduct your own evaluation.
