カーパシー氏は、ソフトウェアというものが過去2回にわたって急速に変化したものと考えています。最初に登場したのがソフトウェア 1.0です。ソフトウェア1.0は誰もがイメージするような基本的なソフトウェアのことです。 ソフトウェア1.0がコンピュータ向けに書くコードであるのに対し、ソフトウェア2.0は基本的にニューラルネットワークであり、特に「重み」のことを指します。開発者はコードを直接書くのではなく、データセットを調整し、最適化アルゴリズムを実行してこのニューラルネットワークのパラメーターを生成するのです。 ソフトウェア 1.0に当たるGitHub上のプロジェクトは、それぞれを集約して関係のあるプロジェクトを線で結んだ「Map of GitHub」で表せます。 ソフトウェア 2.0は同様に「Model Atlas」で表されます。巨大な円の中心にOpenAIやMetaのベースとなるモデルが存在し、そのフォークがつながっています。 生成AIが洗練されるにつれ、ニューラルネットワークの調整すらAIの助けを得て行えるようになりました。これらは専門的なプログラミング言語ではなく、「自然言語」で実行できるのが特徴です。自然言語、特に英語で大規模言語モデル(LLM)をプログラミング可能になった状態を、カーパシー氏は「ソフトウェア 3.0」と呼んでいます。 まとめると、コードでコンピューターをプログラムするのがソフトウェア 1.0、重みでニューラルネットワークをプログラムするのがソフトウェア 2.0、自然言語のプロンプトでLLMをプログラムするのがソフトウェア 3.0です。 カーパシー氏は「おそらくGitHubのコードはも��や単なるコードではなく、コードと英語が混在した新しい種類のコードのカテゴリーが拡大していると思います。これは単に新しいプログラミングパラダイムであるだけでなく、私たちの母国語である英語でプログラミングしている点も驚くべきことです。私たちは3つの完全に異なるプログラミングパラダイムを有しており、業界に参入するならば、これらすべてに精通していることが非常に重要です。なぜなら、それぞれに微妙な長所と短所があり、特定の機能は1.0や2.0、3.0でプログラミングする必要があるかもしれません。ニューラルネットワークをトレーニングするべきか、LLMにプロンプトを送信するべきか。指示は明示的なコードであるべきでしょうか？つまり、私たちは皆、こうした決定を下し、実際にこれらのパラダイム間を流動的に移行できる可能性を秘めているのです」と述べました。 ◆AIは「電気」である カーパシー氏は「AIは新しい電気である」と捉えています。OpenAI、Google、Anthropic などのLLMラボはトレーニングのために設備投資を行っていて、これは電気のグリッドを構築することとよく似ています。企業はAPIを通じてAIを提供するための運用コストもかかります。通常、100万件など一定単位ごとに料金を請求する仕組みです。このAPIには、低遅延、高稼働率、安定した品質などさまざまなバリューがあります。これらの点に加え、過去に多くのLLMがダウンした影響で人々が作業不能に陥った現象も鑑みると、AIは電気のようななくてはならないインフラに当たるというのがカーパシー氏の考えです。 しかし、LLMは単なる電気や水のようなものではなく、もっと複雑なエコシステムが構築されています。OSだとWindowsやMacのようなクローズドソースのプロバイダーがいくつかあり、Linuxのようなオープンソースの代替案があります。LLMにおいても同様の構造が形成されつつあり、クローズドソースのプロバイダーが競合している中、LlamaのようなオープンソースがLLM界におけるLinuxのようなものへと成長するかもしれません。 カーパシー氏は「LLMは新しい種類のOSのようなものだと感じました。CPUの役割を果たすような存在で、LLMが処理できるトークンの長さ(コンテキストウィンドウ)はメモリに相当し、メモリと計算リソースを調整して問題解決を行うのです。これらの機能をすべて活用しているため、客観的に見ると、まさにOSに非常に似ています。OSだとソフトウェアをダウンロードして実行できますが、LLMでも同様の操作ができるものもあります」と述べました。 ◆AIは発展途中 LLMの計算リソースはコンピューターにとってまだ非常に高価であり、性能の良いLLMはほとんどクラウドサーバーで動作しています。ローカルで実行できるDeepSeek-R1のようなモデルも出てきていますが、やはり何百万円もするような機器を何百台とつなげて動かしているようなクラウドサーバーと個人のPCでは出力結果に大きな差が現れます。 カーパシー氏は「個人用コンピューター革命はまだ起こっていません。経済的ではないからです。意味がありません。しかし、一部の人々は試みているかもしれません。例えば、Mac miniは一部のLLMに非常に適しています。将来的にどのような形になるかは不明です。もしかしたら、皆さんがこの形や仕組みを発明するかもしれません」と述べました。 また、PCでは当たり前に使われているグラフィカルユーザーインターフェース(GUI)がLLMには中途半端にしか導入されていないという点も特徴です。ChatGPTなどのチャットボットは、基本的にテキスト入力欄を提供しているだけです。カーパシー氏は「まだ一般的な意味でのGUIが発明されていないと思います」と話しています。 ◆AIは技術拡散の方向が逆 これまでのPCは、政府が軍事用に開発し、企業などがそれを利用し、その後広くユーザーに使われるという歴史をたどってきました。一方でAIは政府や企業ではなくユーザーが広く利用し、その集合知が体系化され、企業が利用するようになります。カーパシー氏は「実際、企業や政府は、私たちが技術を採用するような速度に追いついていません。これは逆行していると言えるでしょう。新しい点であり前例がないといえるのは、LLMが少数の人々や企業の手中にあるのではなく、私たち全員の手中にあることです。なぜなら、私たちは皆コンピュータを持っており、それはすべてソフトウェアであり、ChatGPTは数十億の人々に瞬時に、一夜にしてコンピュータに配信されたからです。これは信じられないことです」と語りました。 ◆人類はAIと協力関係にある AIが利用されるときは、通常、AIが生成を行い、人間である私たちが検証を行うという作業が繰り返されます。このループをできるだけ高速化することは人間にとってもAIにとってもメリットがあります。 これを実現する方法としてカーパシー氏が挙げるのが、1つは検証を大幅にスピードアップすることです。これはGUIを導入することで実現できる可能性があります。長いテキストだけを読むことは労力がかかりますが、絵など文字以外の物を見ることで容易になります。 2つ目は、AIを制御下に置く必要がある点です。カーパシー氏は「多くの人々がAIエージェントに過剰に興奮している」と指摘しており、AIの出力すべてを信じるのではなく、AIが正しいことを行っているか、セキュリティ上の問題がないかなどを確かめることが重要だと述べています。LLMは基本的にもっともらしい言葉をもっともらしく並べるだけの機械であり、出力結果が必ずしも正しいとは限りません。結果を常に検証することが大切です。 この記事のタイトルとURLをコピーする ・関��記事 Metaが既存の生成AIにあるトークン制限をはるかに上回る100万トークン超のコンテンツ生成を可能にする次世代AIアーキテクチャ「Megabyte」を発表 - GIGAZINE 世界最長のコンテキストウィンドウ100万トークン入力・8万トークン出力対応にもかかわらずたった7800万円でトレーニングされたAIモデル「MiniMax-M1」がオープンソースで公開され誰でもダウンロード可能に - GIGAZINE AppleがXcodeにAIでのコーディング補助機能を追加＆Apple Intelligenceの基盤モデルフレームワークが利用可能に - GIGAZINE AnthropicがAIモデルの思考内容を可視化できるオープンソースツール「circuit-tracer」を公開 - GIGAZINE DeepSeekと清華大学の研究者がLLMの推論能力を強化する新しい手法を発表 - GIGAZINE 「現在のAIをスケールアップしても汎用人工知能は開発できない」と考える科学者の割合は76％ - GIGAZINE ・関連コンテンツ TwitterやFacebookで使われている「Apache Hadoop」のメリットや歴史を作者自らが語る 仮想通貨暴落などで苦境に立たされたマイニング業者は余ったGPUを「AIトレーニング用のリソース」として提供している 「AI懐疑論者の友人はみんな頭がおかしい」というブログが登場、賛否両論さまざまなコメントが寄せられる 私たちが何気なく使っているソフトウェアはどのように開発されているのか？ グラフをはみ出した点と線が世界に広がっていく手描きアニメ「Extrapolate」が圧巻 「アルゴリズムって何？」を専門家が分かりやすく解説 機械学習でコンピューターが音楽を理解することが容易ではない理由 生きてるだけでお金がもらえるベーシックインカムこそ「資本主義2.0」だとの主張、その理由とは？
