次期GPT系モデルかもしれない「Horizon Beta」のコーディング性能を検証する

2025年7月30日、OpenRouter上に「Horizon Alpha」という詳細不明のステルスモデルが登場しました。その後「Horizon Beta」という名前に置き換わりました。このモデルは、OpenAIの次期モデルのテスト用ではないか？と注目を集めています。今回は、このモデルの性能をコーディングタスクで検証しました。 https://openrouter.ai/openrouter/horizon-beta 特徴 * コンテキストウィンドウ: 256K（GPT-4.1の1M、o3/o4-miniの200Kと比較して中規模） * スループット: 126.9 tps（Sonnet 4の64.50 tpsの約2倍。コーディング時に体感で早い） * Reasoning機構: なし 本当にOpenAI系のモデルなのか？ OpenAI系のモデルである可能性が議論されています。過去にもQuasar Alpha/Optimus AlphaがGPT-4.1リリース前に登場した経緯があり、今回も同様のパターンかもしれません。 直系のGPT-5ならコンテキストウィンドウは１M

Serena MCPはClaude Codeを救うのか？

「Claude Codeがアホになる問題」が勃発している最中、SerenaというMCPサーバーが「Claude Codeのコンテキスト消費を削減し、応答を改善する」という評価でユーザーたちの間で注目されています。 筆者も実際にSerenaを使ってみたところ、確かにコンテキスト効率の改善（入出力トークンの減少を指します）を実感できました。詳しく調べてみると、このツールは非常にユニークな発想で設計されており、一過性の流行として消費されるには惜しいと感じました。 そこで、本記事では、この機能の背景にある技術的な仕組みを詳しく解説したいと思います。実際の検証も交えながら、Serenaのアーキテクチャとその効果を分析していきます。 現在のコーディングエージェントが抱える課題 現在のコーディングエージェントの多くは、コードを単なるテキストファイルとして扱って逐次的な処理をしています。この根本的なアプローチが、制約を生み出しています。 大規模なプロジェクトで作業する際、エージェントは必要な情報を見つけるために膨大なテキストを読み込まなければなりません。関数の定義を探すだけでも、リポジトリ

Cursorの価格設定変更の騒動について

2024年6月にCursorは価格体系を大幅に変更し、月額20ドルのProプランを「リクエスト数制限」から「トークン使用量制限」へと切り替え、さらに月額200ドルのUltraプランを新設しました。 Updates to Ultra and Pro | Cursor - The AI Code EditorIn collaboration with the model providers, we’re introducing a $200 / mo tier for power users.Cursor Cursorの説明によると、以前は月500リクエストまでの制限で、リクエストごとのトークン使用量は考慮されていませんでした。新しい料金モデルは1回のリクエストで消費するトークン数が大幅に異なるため、単純なリクエスト数制限ではコストを正確に反映できなくなりました。そのため、CursorはAPIベースのトークン使用量課金に移行し、Proプランには月20ドル分のトークンクレジットを含み、それを超えた分は追加課金となる形にしました。 まずいことにCursorはこの変更をポジティブに伝えるた

t-wada vs テスト大好郎

先日一部のClaude Codeユーザーの間で「プロンプトに”t-wadaさんの推奨する進め方に従ってください”と書くとテスト駆動開発のプラクティスを実践してくれる」というTIPSが話題になっていました。 なるほど、TDDやテスト駆動開発という言葉は広まりすぎて「意味の希薄化」が発生し、曖昧な理解のまま自動テストやテストファーストと混同され、それがLLMの学習データにも影響したが、人名を与えるとLLMに「具体的な参照点」を与え、より具体的なプログラミングスタイルに限定させる効果があったのか pic.twitter.com/p6SCPj8YdA — Takuto Wada (@t_wada) June 25, 2025 これは確かに面白い現象で、現にClaudeに直接質問するとt-wadaさんの知識を持っていることがわかります。そこから連想してClaude CodeがTDDをするトリガーとして使えるのなら面白いなと思い色々試してみました。 （ところでこの翌日、最近バイブコーディングにはまってSmalltalkのライブラリをLLMで書いているKent Beckも自著のタイトルを

Claude CodeのTaskツールの並列実行（parallelTasksCount）は分析タスク向け

Claude CodeのTaskツールは派生元となる親エージェントの処理から子エージェントがメッセージAPI呼び出しを非同期で実行しているが、この時の子の数がparallelTasksCountの設定値になる。デフォルトでは「１」に設定されている。 これを上書きするコマンドは以下になる。設定値を上げるとトークン消費量が増加するので注意してほしい。 claude config set -g parallelTasksCount 2 parallelTasksCountはTaskツール実行時の動作を変える。簡単なテスト方法はClaude CodeにTaskツールを使ってくれと直接頼むことだ。parallelTasksCountの数だけ「Initializing N parallel agents…」がコンソールに出力される。 Tyler Burnamのポストではこの並列数がタスク完了速度に寄与するという説明をしているが、筆者が調べたところによるとそれは正確でなかった。 Taskツールの並列実行は親となるエージェント・内部的にはSynthesis Agentと呼ばれる、が子に対して
