data-gtm-click-label="entry-info-description-href">AI（人工知能）モデルの「長期記憶」がにわかに注目を集めている。これまで大規模言語モデル（LLM）が一度に処理できるトークン量を表す「コンテキストウインドー」には限界があり、プロンプトで入力された情報を長らくとどめておけなかった。この弱点を克服できればLLMの用途は一気に拡大する。「鍵を握るのは長期記憶だ」――。2025年2月、米Open AI（オープンAI）と企業向けAIエージェント「クリスタル・インテリジェンス（Cristal intelligence）」を共同開発することを発表したソフトバンクグループの孫正義会長兼社長は、こう見通しを語った。長期記憶に関する特許も複数取得済みだという。クリスタル・インテリジェンスは、企業が抱える情報システムのソースコードやデータを学習し、自律的に業務を代行する。この構想の実現を左右するのが長期記憶というわけだ。オープンAIのサム・アルトマンCEO</p> <p

IT人材を確保しやすくみずほ銀行がMINORIのクラウド移行を決めた狙いは大きく3つある。 1つ目はシステム障害から早期に復旧する能力を指す「レジリエンス」の向上だ。金融庁は2023年4月に「オペ</p> <p class="entrylist-contents-thumb"> <span

Global Mobilityの協力の下、中国での自動車販売データ約2億台分を入手し分析した。外資系メーカーからシェアを奪って成長しているのは中国の現地メーカーだ（図1）。中でも中国・比亜迪（BYD）は2020年ごろまでは販売台数で目立たなかったが、2021年ごろから急速に成長し、その速度も年々増加して</p> <p class="entrylist-contents-thumb"> <span

Japanが2025年1月に発表した予測によれば、2025年の国内IT市場規模は前年比8.2％増の26兆6412億円を見込む。旺盛な国内IT需要に応えるため、次の一手に乗り出すITベンダーの動きが見え始めてきた。2024年には富士通やNEC、三菱電機がグループ会社の再編を相次いで発表した他、NTTデータやSCSK、KDDIは自社の事業とシナジー効果を見込める企業の買収へ乗り出した。積極的に組織再編と構造改革を進める富士通中でも動きが大きいのは富士通だ。2019年に時田隆仁氏が社長に就任して以降、急速な組織再編を進めてきた。富士通本体が関係する、国内の主な組織変更だけでも、再編の対象になったグループ会社は約40社に上る。直</p>

Sonnet」を採用している企業が目立った。どちらも両社の主力モデルであり、回答精度は「申し分ないレベルに達している」との評価が多い。このため、企業は自社環境との親和性や利用料金など精度以外の観点から、選択肢を絞り込んでいる。利用料金は推論に強い「o1」で一気に高くモデル選びにおける重要な要素が利用料金だ。LLMの利用料金は、文章を単語や文字で分割した「トークン」という単位による従量課金が一般的である。入力及び出力したトークン数の合計で利用料金が決まる。 LLMの利用に当たってはクラウド大手が提供する生成AI基盤を活用するケースが多い。こうした生成AI基盤ではRAG（検索拡張生成）などの周辺サービスも利用でき、システムを開発しやすいためだ。この場合</p> <p class="entrylist-contents-thumb"> <span
