Microsoft’s AI unit has shipped two first‑party foundation models — MAI‑Voice‑1 and MAI‑1‑preview — marking a clear acceleration of in‑house model development even as the company continues to integrate and promote OpenAI’s frontier models such as GPT‑5 across its product stack. The launches are...

Microsoft has quietly crossed a strategic Rubicon: after years of tight integration with OpenAI, the company has begun shipping its own first-party foundation models — notably MAI-Voice-1 and MAI-1-preview — and is positioning them inside Copilot and Azure as the start of a long-term bid to...

Microsoft’s AI group quietly cut the ribbon on two home‑grown foundation models on August 28, releasing a high‑speed speech engine and a consumer‑focused text model that together signal a strategic shift: Microsoft intends to build its own AI muscle even as its long, lucrative relationship with...

Microsoft’s Windows lead has just sketched a future in which the operating system becomes ambient, multimodal and agentic — able to listen, see, and act — a shift powered by a new class of on‑device AI and tight hardware integration that will reshape how organisations manage and secure Windows...
