Building a new class of safer, more capable AI systems we call Humanist Superintelligence: AI that is always aligned, controllable, and in service of humanity.

[Mustafa Suleyman @mustafasuleyman]

Our MAI Diagnostic system is now 1.7x more accurate than physicians in the ED, even when they have access to the web to look things up.

It's also lower cost & does fewer medical tests to get to its diagnosis.

[1/4] How well do speech recognition systems handle real conversations in 21 languages?

Today we're releasing DAI-ASR-I18N, a benchmark that evaluates 14 systems on speech recognition and speaker diarization in natural, unscripted conversation

[Mustafa Suleyman @mustafasuleyman]

We now have state-of-the-art pre-trained base models in the 3T-parameter weight class, built entirely in-house at MAI.

Post-training results coming soon -- stay tuned!

Lots of details in our technical blog post.

[Microsoft AI @MicrosoftAI]

MAI is hill-climbing 61% faster than any other lab in image generation. We've gained +283 Elo on text-to-image in 10 months to optimise the pareto frontier.

[Microsoft AI @MicrosoftAI]

No lab has reached the image frontier faster.

Microsoft AI: 864 → 1147 Elo in nine months. That's 377 points a year — 1.6× the next-fastest climb on the board.
