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

GitHub Copilot NESの内部実装が公開、そして続・AIエディタ戦争

Copilot NESとは Copilot NES(Next Edit Suggestions)は2025年2月にリリースされたGitHub Copilotの内部機能です。コードの変更に連動して必要となる次の編集を予測し、タブキーを押しているだけで複数箇所にわたる修正を提案してくれます。通常のコード補完がカーソル位置の続きのコードを予測するのに対して、Copilot NESは「エディタ上の編集操作」の単位で続きを予測して補完します。 GitHub Next | Copilot Next Edit SuggestionsGitHub Next Project: Can we improve Copilot code completion by suggesting the next logical change, wherever it is in your project?GitHub Next この仕組みはCopilot NESの元ネタであるCursor Tab(Copilot++)によって実用化されましたが、Cursorはプロプライエタリなソフトウェアなので内部の詳細が分かり
