オープンAIの新AI「GPT-6アストラ」、価格と実力の詳細が判明

OpenAIの新AI「GPT-6 Astra」は、本や資料をまとめて100万文字ぶん読み込めるうえ、コード作成やパソコン操作でも世界最高クラスとされ、9月4日からチャットGPTに搭載されたほか、他のサービスから呼び出す仕組み(API)やAmazonのクラウドサービスからも使えるようになった。

今週、僕が一番気になった変化

「企業の32%がソフトを買わず、AIで作るようになった」というNewsは、かなり大きな転換だと思っています。

僕自身も今、CRMや個人向けのWeb OSをAIと一緒に作っていますが、数年前なら数百万円〜数千万円・数か月必要だったものが、数日で動くところまで来ています。

これは単なる「開発効率化」ではなく、ソフトウェアを買うという行為そのものが変わり始めているんじゃないかと思っています。

今週、実際に作ったもの

AIで作って、使って、考えたこと。動画や画面とともに、開発の背景と気づきを紹介します。

LAB · RELAY

I built the CRM I actually wanted to use from scratch with AI.

Astraを使い、構想から約2日で、クライアントとの関係を「3Dの街」として育てるWebアプリに。AIで作り、AIが入力・整理も支えるCRM「Relay」を紹介します。
