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
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? 主にRedditやXで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。 Horizon Beta

Serena MCPはClaude Codeを救うのか?
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

The /o in Ruby regex stands for “oh the humanity!”
Your code using the /o modifier Source: wikipedia Hi there! Do you like Regex? Do you like performance? Do you like creating confounding bugs for yourself rooted in the mechanics of the Ruby VM itself? If you said yes to all of the above, have I got a feature for you! But first, let’s start with a story. The cliffs of insanity I was recently reviewing some code, and part of the functionality was about matching.

How Parcel bundles React Server Components
Parcel v2.14.0 added support for React Server Components. This post is a deep dive into the internals: how RSCs integrate with a bundler, what directives like "use client" actually do, how code splitting works and how RSCs improve it, etc.

We built the security layer MCP always needed
Today we’re announcing the beta release of mcp-context-protector, a security wrapper for LLM apps using the Model Context Protocol (MCP). It defends against the line jumping attacks documented earlier in this blog series, such as prompt injection via tool descriptions and ANSI terminal escape codes.
