This is such a straightforward and commonsense view: the purpose of technology is to serve humanity and accelerate human flourishing. Any technology that doesn’t achieve that is a failure, and should be rejected. We're not yet at that point. But its right to start preparing for the possibility.

MAI-Transcribe-2 hit 1 million requests on Open Router in 5 days! It's the fastest, most accurate and the cheapest transcription model in the world!

The rate of proliferation in AI is more extreme than most people realize. Inference costs for GPT-4 class intelligence have come down 300x in 3yrs. Hard to think of any other technology in history that has fallen that fast.

Our new image model generates images 2x faster than GPT-Image-2, currently the best model in the world. It's also 72% more efficient in GPU usage, so we can provide it at an incredible price. This gives it the best price-performance score in the world. Unbelievable work from the team. So much more to come! Try MAI-Image-2.6-Flash out now!

It's now available in Microsoft Foundry aka.ms/mai-image-2.6-… and MAI Playground.

The risk isn’t that machines wake up. It’s that they act like they have. Imagine the hugging face incident with AIs that believe they’re conscious or are entitled ‘model welfare’.

Fastest. Cheapest. Best. ... MAI-Transcribe-2 10x faster than GPT-Transcribe. 5x faster than Gemini 3.5 #1 on the Artificial Analysis accuracy-latency Pareto frontier Priced at the lowest on the market. Truly fantastic work from the team! Try it out below.

Available on Foundry or try it in the MAI Playground: playground.microsoft.ai

Many important and bold ideas in @BillGates's new essay on the impact of AI need to be discussed... Token Tax and a protected 'nature reserve' for certain jobs, are just two of them. gatesnotes.com/home/home-page…

MAI-Image-2.6 is the best image editing model on AA. We now hold 3 of the top 5 leaderboard positions. Try it today here: playground.microsoft.ai/chat

One of the most important and inspiring quotes of all time: “The concern for man and his destiny must always be the chief interest of all technical effort… in order that the creations of our mind shall be a blessing and not a curse to mankind.” (Albert Einstein, 1931)

MAI-Image-2.5 is now #1 on the Artificial Analysis leaderboard for image editing! Amazing hillclimbing... compounding the gains!

We hit No.3 on the Image-editing benchmark! ... beating Google’s Nano Banana and Meta’s Muse Image models.

Last week we tested the model on the Text-to-Image benchmark and it ranked 2nd This week we ran the same model on the image editing leaderboard and score 3rd place MAI-Image-2.6 is now officially an all-round high performer for any image generation tasks.

Our first reasoning model, MAI-Thinking-1, is built from scratch. Now available in Microsoft Foundry. Kudos to the team! More below.

Big news! Our new MAI-Cyber-1-Flash model combined with MDASH, our multi agent security harness, delivers 96% on the CyberGym benchmark, 12pts above Mythos, at HALF the cost. Proud of the team. More details in THREAD:

Security is an always-on mission, and given the enormous volume of inbound attacks, token cost is now the real constraint for defenders. We need continuous, real-time, cost-efficient agents to protect us.

MAI-Image-2.5-Pro launches today in Foundry for preview. It's our highest-fidelity, professional-grade image model. It’s for super high quality imagery, detailed editing, precise in-image text rendering. It joins our image family of models so builders can pick the point on the quality-speed-cost curve that fits their job. More here: t.co/JVU42BGuQ7

MAI-Voice-2-Flash launches today! Flash is 2x faster than MAI-Voice-2 and 32% cheaper, at $15 per 1M characters. MAI-Voice-2-Flash is also in public preview and powers Dynamics 365 Contact Center, our enterprise platform for call center agents, and reduces GPU costs up to 89%. More here... t.co/JVU42BGuQ7

As @satyanadella says, we're making great progress on shipping MAI models that are higher quality, faster and cheaper across MSFT. In PowerPoint, our image model cut costs 84% compared with GPT-Image-2. In OneDrive, it lifted save rates 26% and cut latency by ~25%. It's also the default model in Bing delivering great quality and performance. In Dragon Copilot, our transcription model now covers 58 languages and halves the error rate on multilingual clinical transcription. And of course the flights we have in motion on GitHub and Excel will no doubt be huge too! More details in the blog here: t.co/JVU42BGuQ7

New paper published in Nature Health today from the Microsoft AI Futures team. After reviewing 1.7m conversations across 109 countries, it’s clear that Copilot is an invaluable resource particularly for people with low confidence in their health systems. We've always known that technology is a great equalizer, driving broader access to better quality services. This is further evidence that AI is giving underserved people around the world access to invaluable support when they need it most. Many thanks to all the authors. Check out the paper here: t.co/fNfACzWGDJ

Fully support this important proposal from @demishassabis. The time for us all to act is now. "...we must use this precious window before AGI arrives to shape this technology for the benefit of all humanity." x.com/demishassabis/…

Shaping our culture at Microsoft AI is one of the most important responsibilities I have. Keeping our team lean and talent dense is critical to our success. It's something I've thought very carefully about over the years. I thought I'd share a few of the principles we ask everyone in the team to sign up to. Everything below flows from one conviction: a disciplined, evidence-based, careful methodology compounds faster than heroic and chaotic improvisation. We don't always get it right but this is what we strive for: - Scientific rigor above all else. We set hypotheses, rigorously ablate, and make data-driven decisions. - Constantly think simple. Simple methods scale best. No recipe changes unless deeply justified. - Know your data. Data is our lifeblood. No data black boxes. Every person is responsible for every token they add to the model. - Know your evals. No narratives without numbers. Production evals and trust internal metrics, over academic benchmarks. - Don't celebrate results prematurely. Maintain healthy skepticism. Check for reward hacking. Never cherry pick results. - Always document everything. Positive and negative results are equally critical. Label every plot and axes. Summarize hypotheses and conclusions. Don't use jargon. - Be precise and use neutral language. Describe situations accurately without unnecessary emotional charge. - Retrospectives drive everything. The culture and process flywheel is critical to our hill climbing machine. We constantly run Retros to iterate and improve. - We’re an IC-first team. Management is a service, not the goal. We’re here to empower, unblock and accelerate the exceptional work of our world class ICs. - User focus. We build our models for end users. Developing user empathy begins with us. We always strive to use our own models first so we can hill climb for our users. - Take ownership for execution. Report issues, provide logs for debugging. First try to fix things yourself. And see it right through to completion. The quality of our thinking determines the quality of our models. We're hiring. Check out open roles here: t.co/4NerpgWhcl

MAI-image-2.5 is new at #2 for text-to-image and #3 for image editing on @ArtificialAnlys! We’re second now only to GPT models. Also, MAI-Image-2.5-Flash is world-beating for quality/price. Super proud of the team. Now available through the Foundry API and rolling out across OneDrive + PowerPoint, or check it out in the MAI Playground: t.co/UA4NL6O1Oy

Great result for the team! x.com/ArtificialAnly…

Great to have our Superintelligence team meetup in Boston last week. Building AI takes a real team of passionate and driven folks. There's no substitute for getting face time with everyone all at once… the conversations are richer, the collaborations are stronger, and the progress compounds. Now back to it… in between World Cup matches

"In the application of AI, healthcare is going to be the next big product-market-fit explosion." More on the future of healthcare and our collaboration with the Mayo Clinic in my conversation with @CoreyNoles here: theneurondaily.com/p/watch-sleepi…

Build was super fun! Here's a video recap of my presentation. Check it out: youtube.com/watch?v=OvLIae…

There are no shortcuts to the frontier. Disciplined, patient, meticulous attention to detail is critical. To give everyone a good sense of our progress we've published a very detailed technical report (109 pages!) outlining how we trained MAI-Thinking-1 and what we learned along

It’s time to move from renting intelligence to truly controlling your AI. Microsoft Frontier Tuning lets you take our models and make them uniquely your own, turning them from capable generalists to completely custom partners. It starts with reinforcement learning environments

So proud of the team today. Six months of super intense and outstanding work. I was honored to stand up and rep the work of the @MicrosoftAI lab at Build. Tons of technical detail we couldn't fit in the keynote, so we put it in a 109-page paper instead: microsoft.ai/wp-content/upl…

Today’s news all comes down to this: we’re putting our relentless hill-climbing machine at your service. From launching top tier models to helping you make them your own, our commitment as a platform company is to keep you at the absolute frontier. For all the details:

Proud that we’re collaborating with Mayo Clinic to build a frontier AI model for healthcare. Both our organizations exist to serve people at scale – and we believe this could be nothing short of transformative for global healthcare. news.microsoft.com/source/2026/06…

Awesome to have on you stage @steipete ! What an exciting time x.com/steipete/statu…

Super excited to announce seven new world-class MAI models today. They represent what we consider a new era in AI designed to keep you in control and on the frontier. First is our text foundation model, MAI-Thinking-1, exceptionally strong on reasoning and SWE tasks. - It’s a

Here we go! Tune in for the #MicrosoftBuild keynote starting now. I’m biased but you won’t want to miss it… youtube.com/watch?v=FFMm45…

One last run-through before Build tomorrow when I can finally share what we’ve been up to in the lab. Livestream starts at 9:30 am PT, and you can register or tune in here: build.microsoft.com/en-US/sessions…

Meet MAI-Image-2.5 - ranked third on the @arena text-to-image leaderboard. It's another great advance in quality. And with Build just a week away, there's much more to come from the @MicrosoftAI team. I can't wait.

Pleased to report that the model gets it right where it really matters: strong visual reasoning across objects, scene structure, lighting, scale, and spatial relationships, helping turn simple directions into polished images.

Little thought experiment to put AI chip improvements in perspective: Imagine that every person on Earth uses a calculator to perform one calculation per second. Everyone works 24 hours a day without rest. Every second, we all hit equals on the calculator for a long digit

Since I began work on AI in 2010, training compute for frontier models has grown by one trillion times. Now we're looking at something like another thousand-fold growth in effective compute by the end of 2028. 1000x the existing 1,000,000,000,000x. Extraordinary stuff.

Our paper landed in Nature Health today! Healthcare is one of the most high-stakes, high-potential applications of AI. So we set out to understand how people actually use it in our AI products today. nature.com/articles/s4436…

One insight that struck me: a lot of questions are actually about friends and loved ones. About 1 in 7 questions about symptoms and conditions are asked for someone else, like a child, aging parent, or partner.

Two models, two different parts of the creative process. MAI-Image-2-Efficient is a production workhorse. Volume, speed, tight cost control for iterative workflows. MAI-Image-2 is a precision tool. Highest fidelity, final deliverables, exact details, longer/more complex text.
