[Microsoft AI](https://microsoft.ai/news/two-new-in-house-models/) officially introduced two **in-house artificial intelligence models**, **MAI-1-preview** and **MAI-Voice-1**, showcasing them as foundational pieces for the future of its **AI-powered services**. The models are now live in early-stage testing and some are already integrated into products like **Copilot Daily** and **Podcasts**. > Excited to share our first [@MicrosoftAI](https://twitter.com/MicrosoftAI?ref_src=twsrc%5Etfw) in-house models: MAI-Voice-1 and MAI-1-preview. Details and how you can test below, with lots more to come⬇️ [pic.twitter.com/LtL2YmzuTv](https://t.co/LtL2YmzuTv) > > — Mustafa Suleyman (@mustafasuleyman) [August 28, 2025](https://twitter.com/mustafasuleyman/status/1961111770422186452?ref_src=twsrc%5Etfw) ## Microsoft’s First In-House Models For the first time, [Microsoft](https://sqmagazine.co.uk/microsoft-statistics/) is stepping into the spotlight with AI models built entirely within its own AI division, **Microsoft AI (MAI)**. This marks a notable shift from its previous heavy dependence on **OpenAI models**. **MAI-1-preview**, Microsoft’s first **foundation model**, is a **mixture-of-experts architecture** trained on roughly **15,000 [Nvidia H100 GPUs](https://sqmagazine.co.uk/ai-chip-statistics/)**. The model is designed for **text-based use cases** like following instructions and answering user queries. It is now in **public testing** on the benchmarking platform **LMArena**. **MAI-Voice-1**, on the other hand, is a **speech generation model** that can produce a **full minute of expressive audio in under a second** using just one GPU. It supports **both single and multi-speaker conversations**. ## **Where You Can Try Them**? **MAI-Voice-1** is already in action within **Copilot Daily** and **Podcasts**, delivering **AI-generated news and discussions**. Users can also interact with it directly via **Copilot Labs**, which offers customization in **voice and tone**. It’s ideal for **storytelling**, **guided meditations**, and interactive experiences like **choose your own adventure** prompts. > 🚨Text Leaderboard Update: > > A new model provider, [@MicrosoftAI](https://twitter.com/MicrosoftAI?ref_src=twsrc%5Etfw) has broken into the Top 15 this week! > > 💠MAI-1-preview by [@MicrosoftAI](https://twitter.com/MicrosoftAI?ref_src=twsrc%5Etfw) debuts at #13. > > Congrats to the Microsoft AI team! As the Text Arena is one of the most competitive races, breaking into the Top 15 is no small… [pic.twitter.com/y2q3nHnLlz](https://t.co/y2q3nHnLlz) > > — lmarena.ai (@lmarena\_ai) [August 28, 2025](https://twitter.com/lmarena_ai/status/1961112908026593557?ref_src=twsrc%5Etfw) **MAI-1-preview** is being tested on **LMArena**, and Microsoft is collecting feedback through **trusted testers** and early adopters. The company is preparing to roll it out for specific **Copilot text features** in the coming weeks. ## Strategic Shift Away from OpenAI? While Microsoft continues to collaborate with **[OpenAI](https://sqmagazine.co.uk/openai-statistics/)** and leverages its models in many current products like **[Bing](https://sqmagazine.co.uk/bing-vs-google-statistics/)** and **Windows 11**, this move reflects a **potential long-term shift**. Reports suggest Microsoft may be working to **diversify its AI infrastructure**, especially as OpenAI itself expands partnerships with other cloud providers such as **[Google](https://sqmagazine.co.uk/google-search-statistics/), CoreWeave, and Oracle**. In fact, Microsoft has already listed **OpenAI as a competitor** in its recent annual report, hinting at the evolving dynamics between the two. ## Microsoft AI’s Vision for the Future Microsoft AI says these new models are part of a broader mission to create **responsible**, **reliable**, and **human-centric AI companions**. The team believes **voice is the future interface** for AI and is committed to delivering tools that are **supportive**, **expressive**, and tailored to **individual needs**. The company also hinted at the **operational readiness** of its **next-gen GB200 compute cluster**, showing it’s gearing up for even more powerful model development. Microsoft wants to orchestrate a **diverse ecosystem of specialized models** that can handle a wide range of user tasks with greater **precision** and **personalization**. ## SQ Magazine’s Takeaway I think this is Microsoft signaling it’s ready to play in the big leagues of AI, **not just as a partner of [OpenAI](https://sqmagazine.co.uk/openai-vs-anthropic-statistics/) but as a serious builder in its own right**. **MAI-Voice-1 sounds slick**, and honestly, the speed and flexibility it brings could reshape how we interact with AI day to day. But **MAI-1-preview is the real game changer**. If Microsoft nails this model, we might soon see a world where **Copilot relies less on OpenAI and more on its own tech stack**. That’s a major power move.
