Xiaomiが、新型の折りたたみスマートフォン「Xiaomi 18 Fold」を、9月7日に中国で発表することをX公式アカウントで予告している。

本製品は、Xiaomi自社開発したプロセッサ「Xiaomi XRING O3チップ(※Oはアルファベットの大文字O《オー》)」を採用した最初のフラグシップ製品に位置付けられる。同社はこれまでも「Xiaomi XRING O1」という自社開発のチップを開発しており、2025年に発売した「Xiaomi 15S Pro」に搭載した。

3nmプロセスで製造されたXRING O3は、モバイル向けプロセッサでは初めて次世代低消費電力メモリ規格「LPDDR6」をサポートする。メモリの帯域幅は113.8GB/sで、データ転送速度がXRING O1から48%高速化したという。NPUのAI性能は45%高速化したとする。CPUは60%、GPUは85%の性能アップを果たし、「AnTuTu Benchmark」アプリで522万超えのスコアを出したことをアピールしている。

その他の詳細なスペックは明かされていないが、ディスプレイを開くと横長になるパスポート型の形状であることが分かる。この形状は、同じ中国メーカーではHuaweiが「Pura X Max」でいち早く採用した他、国内でもサムスン電子が7月に発売した「Galaxy Z Fold8」でも取り入れている。そして、9月9日(米国太平洋標準時)に発表されることが予想されるiPhone初の折りたたみスマホも、この横長ディスプレイを採用することが予想されている。

Xiaomiとしては、Appleが発表する一足先に、同様の形状(である可能性が高い)折りたたみ端末を発表することで、中国市場で先手を打ちたいと考えているのかもしれない。日本市場でもサムスン電子に加えてOPPO、モトローラ、Google、ZTEなどが折りたたみ端末を投入しており、折りたたみ市場が活性化する兆しが見えることから、日本への投入も期待される。

なお、Xiaomi 18 Foldはドイツ・ベルリンで開催されている展示会「IFA 2026」で実機が展示される。

4 steps of "Decision Driven Architecture" to formulate the decision-making process

Against the backdrop of the increasing complexity of architectural decision-making in the AI era, we proposed a "decision-driven architecture" that consists of four steps: quantifying requirements, setting evaluation axes, comparing proposals, and recording results. Using the choice between monolith and microservices as an example, he explains the importance of recording background information and prioritizing.

Anthropic test releases common specification "MHS" for AI agents to safely operate physical devices

On August 27, Anthropic released a test version of the Model Hardware Standard (MHS), a common specification for AI agents to safely operate physical equipment such as microscopes and robot arms. The plan is to initially provide the service only to scientific research laboratories and some advanced manufacturing industries, and to open source it once safety evaluations and operational guidelines are finalized. MHS is centered around a common driver that enables automatic collaboration between AI and devices, reducing the weeks or months typically required to connect devices from hours to minutes. In a demonstration at quantum computer company QuEra, AI reduced a task that would have taken four experts months to just six seconds overnight, achieving a success rate of 99.3%.
