個人向けGeminiのモデル選択が厳格化 無料ユーザーが使えるのは「Flash-Lite」のみに

Quick Look

米Googleは10月初旬にGeminiのサポートページを更新し、個人向けGeminiアプリでのAIモデル利用を契約プランに応じて制限すると発表。無料ユーザーは10月9日から「Flash-Lite」のみ利用可能となり、有料プラン「AI Plus」以上で「Flash」、さらに「AI Pro」以上で「Pro」モデルが利用可能になる。

AI-generated summary

Why It Matters

Googleは5月から、Geminiの利用上限を単純な回数ではなく、プロンプトの複雑さや使用する機能、チャットの長さなどに応じて算出する方式に変更している。

米Googleは10月初旬に更新したGeminiのサポートページで、個人向け「Gemini」アプリで利用できるAIモデルを、加入しているGoogle AIの契約プランに応じて変更すると告知した。Google AIの有料プランを契約していない無料ユーザーについては10月9日から変更を適用し、利用できるモデルは「Flash-Lite」のみになる。

変更後に利用できるモデルは「Flash-Lite」「Flash」「Pro」の3段階となり、無料ユーザーはFlash-Liteのみ、「Google AI Plus」プランではFlash-LiteとFlash、「Google AI Pro」と「Google AI Ultra」では3モデルすべてを利用できる。各プランのサブスクリプション料金は以下の通り。

つまり、無料版のGemini自体が使えなくなるわけではないが、利用できるモデルの選択肢は限定される。Flashを使うにはAI Plus以上、最上位のProモデルを使うにはAI Pro以上の契約が必要になる。

各モデルでは、推論に割り当てる処理量を「low」「medium」「high」から選択できる仕様となっている。高い設定ほど複雑なタスクへの対応力や回答の詳しさが増す一方、利用上限の消費も多くなる。さらにAI ProとAI Ultraでは、並列に推論してより複雑な問題に取り組む「Deep Think」も利用できる。

Googleは5月から、Geminiの利用上限を単純な回数ではなく、プロンプトの複雑さや使用する機能、チャットの長さなどに応じて算出する方式に変更している。上限は5時間ごとに更新され、週単位の上限も設けられている。無料版を「標準」とすると、AI Plusはその2倍、AI Proは4倍の利用枠を持つ。AI Ultraは契約内容に応じてAI Proの5倍または20倍となる。画像・動画・音楽生成、Deep Research、Proモデル、拡張推論などは利用枠を比較的多く消費する。

今回のモデル変更は個人アカウントが対象。無料ユーザーには10月9日から適用を開始する予定だ。AI Plusユーザーについては、変更が適用される時期をメールで案内するとしている。

Docomo fails to explain and obtain consent for RCS use, affecting approximately 16,000 cases

NTT Docomo announced that RCS was available to approximately 16,000 users who signed up for new MNP contracts at stores between September 17th and September 25th without receiving an explanation of important matters regarding the use of RCS or obtaining consent for third-party provision to Google Asia Pacific. There were 225 messages that were actually sent and received, and the messages were encrypted, but this was considered problematic from the perspective of secrecy.
