Today we’ve made Think Deeper free and available for all users of Copilot.

This now gives everyone access to OpenAI’s world class o1 reasoning model in Copilot, everywhere at no cost. I urge you to give it a try. It’s truly magical. Think Deeper helps you:

- Get in-depth advice on how to manage a career change, with detailed breakdowns of educational milestones and options, resources on where to look for roles, strategies for getting in the door and industry trends you absolutely need to know.

- Plan that epic project. Brain dump everything into Think Deeper and watch it churn through it all and spit out a step by step guide to making it happen. I've tried this on a few things (fitness routine, big launch coming up) and it’s genuinely so helpful.

- Deep dive any topic. Want to learn about something? It nails it! Not a substitute for human teaching, but an extraordinary augmentation. When I get obsessed with something I turn to Think Deeper these days. Lately: the history of India, what’s happening to ocean currents.

The possible uses here are really infinite. I'm genuinely so excited that our tens of millions of users are all getting this opportunity. We've got so much more in the pipeline right now that I can't wait to tell you about. But in the meantime life is full of chaos and complex problems. Let Think Deeper shoulder some of the mental load!

One more day until I'm allowed to fill you in on some new stuff we've been working on...

One thing I’ve been loving on my commute lately: catching up on the news through a conversation with Copilot. I’ll ask it to update me on the day’s top headlines and a few topics I’m extra interested in (renewable energy, healthcare breakthroughs, any UK news), then it’s a choose-your-own adventure.
 
Super helpful to be able to interrupt with follow-up questions, get more detail on-demand. Literally talk through anything confusing or go down a rabbit hole that sparks your interest.
 
Aso noticed I absorb it a lot more with the back and forth - just sticks better than passively listening to a podcast. Give it a go!

We just dropped what we believe is the world's largest study of AI conversations - and it found that what you talk to AI about actually has a lot to do with what time it is.

Researchers across both the Microsoft AI Futures team and Data Science team analyzed 37.5M de-identified conversations from between January and September in Copilot and looked for patterns in not just what people talked about, but when. They found 3 different trends by day, time of day, and time of year - and 1 rock solid constant.

1. The one thing on users' minds around the clock: health. When we ranked what topics people were talking to Copilot about, for mobile users health was #1 no matter what day, month, or time it was. This is a huge responsibility for us, and one we're super focused on.

2. Day of the week: They did find some big swaps between weekday and weekend trending topics. Gaming had a two day spike every week on Saturday and Sunday, while most coding-related conversations happened between Monday and Friday.

3. Time of day: We've all had those existential musings in the middle of the night - and that shows up in the data, with philosophical conversations increasing in the early hours of the morning. On the other hand, we saw upticks in travel-focused conversations happening most often during commute hours, with people daydreaming about where they'd rather be.

4. Time of year: Seasonal differences also affected trending topics - for example, in February, relationship-related conversations spiked on Valentine's Day. And interestingly, "Personal growth and wellness" related conversations surged over the 2-3 days before with people seeming to focus inward.

Zooming out, what the data means to me is people are truly turning to Copilot as a companion. Not just a specific type of tool, but a sounding board and support across all these different moments that make up our lives - from existential overthinking at 2 am to when you're stuck on a certain video game level over the weekend.

Studying these patterns is about understanding what matters most to our users - and where we can help. What's important when using desktop vs. mobile? How should Copilot adapt to you throughout the week? What features would help support people in these day-to-day rhythms, what topics should be our biggest priorities? It's fascinating stuff, and this is how we make AI more useful, for more people, more often.

Big kudos to Beatriz Costa Gomes, Sophia Chen, Connie Hsueh, Deborah Morgan, Philipp Schoenegger, Yash Shah, Sam Way, Yuki Zhu, Timothé Adeline, Michael Bhaskar, and Seth Spielman across both the MAI Futures team and Data Science team for pulling this together.
