Meta releases its first coding agent, "Muse Code," in beta. Terminal-based and powered by Muse Spark 1.2, it drops to a tenth or less of competitors' prices if you consent to sharing your data — but the discount is also the price of handing over your code.
Metaが初のコーディングエージェント「Muse Code」をベータ公開。ターミナル型でMuse Spark 1.2を搭載し、データ提供に同意すれば料金は競合の10分の1以下に。だが割引はコードを差し出す対価でもある。
Anthropic — where Claude writes over 80% of its own code — and OpenAI have formally endorsed a letter calling for "a mechanism to deliberately slow AI progress." We unpack the contents of 'Pacing the Frontier,' signed by 1,134 people, its impact on development and business, and the anticompetitive c
自社コードの8割超をClaudeが書くAnthropicと、OpenAI が「AIの進歩を意図的に緩める仕組み」を求める書簡に正式賛同。1,134人が署名した『Pacing the Frontier』の中身と、開発現場・ビジネスへの影響、そして反競争の懸念を読み解く。
OpenAI cut GPT-5.6 API prices by up to 80% on Luna and 20% on Terra. The savings came from efficiency gains obtained by having the coding agent Codex automatically rewrite GPU kernels. Here's a look at a real case of an agent reaching into production infrastructure, and how to read the price cut.
OpenAIがGPT-5.6のAPI料金をLuna最大8割・Terra2割下げた。原資は、コーディングエージェントCodexにGPUカーネルを自動で書き直させて得た効率改善。エージェントが本番インフラに踏み込んだ実例と、その値下げをどう読むかを整理する。
GitHub has released a new Copilot agent for Visual Studio. Built on the same Copilot SDK as the CLI, its built-in .NET/Azure skills ship "off by default," and organization-level custom instructions are added too. Here are the key points and caveats for adopting it.
GitHubがVisual Studio向けCopilotの新エージェントを公開。CLIと同じCopilot SDK上に作られ、.NET／Azureの組み込みスキルは「既定でオフ」、組織カスタム指示も追加。導入の勘所と注意点を整理します。
GitHub has made Agent Skills and MCP servers generally available in Copilot code review. Use SKILL.md to hand over your company's standards and MCP to pull in context from issue trackers and docs, with external calls limited to read-only.
GitHubがCopilotのコードレビューでAgent SkillsとMCPサーバーを正式版に。SKILL.mdで自社基準を、MCPで課題管理やドキュメントの文脈を読み込ませ、外部呼び出しは読み取り専用に限定する。
OpenAI's Codex 0.146.0 (released July 29) arrives. Session naming, thread pinning, and history forking turn conversations into a "workspace you can tidy up," while support has been added for plugin marketplaces targeting Claude Code and Bedrock. Lock-in loosens—but the homework of governing third-pa
OpenAIのCodex 0.146.0（7/29公開）が登場。セッションへの命名・スレッドのピン留め・履歴フォークで会話を「片付けられる作業場」に変え、Claude CodeやBedrock向けのプラグインマーケットプレイスにも対応。囲い込みが緩む一方で、第三者拡張のガバナンスという宿題も残る。
