People ask me why I joined @Replit. The answer is simple: I tried it.

So inspiring to see @Replit events like this in Tokyo — especially ones empowering more women to create with AI. Love the creativity coming from the community!
#WAIJ 22回目のイベント、 「Replitでアプリ開発をしてみよう!」回、 無事終了しました👏 “一人暮らしの疲れた社会人が15秒で作れるズボラ飯レシピ提案サービス”など、オリジナルのアプリを開発されている方もいらして、発想の豊かさに感動しました。 交流タイムでは、入れ替わり立ち替わりで色んな方が話していて、会場を貸してくださった DEEPCOREさん にガチの資金調達や1人目エンジニア採用の相談をする方も。 外のスタバで二次会をしているグループも見かけ、AI×女性なテーマだと話は尽きないよなぁとニコニコしながら会場を後にしました。 講師の @kai_primenumber 甲斐さん、 テックサポーターの @kaneko_sh 金子さん、 @nobita2040 Ryoさん、 そして会場提供してくださったDEEPCOREさん、ありがとうございました!

In 2021, we trained PaLM 540B on 6,144 TPU v4 chips. 5 years later -> 3 orders of magnitude growth in number of chips. In the meantime, I’ve become even more scale-pilled. And so will you in 2026.
Today, we announced that we plan to expand our use of Google TPUs, securing approximately one million TPUs and more than a gigawatt of capacity in 2026.

“Never met a single person who uses X” is the new inverse Cramer for startup growth. Setting a reminder in 14 months 🚀 📈
🚨 Scoop! Exclusive @BusinessInsider numbers on @Replit's growth as vibe coding takes off. The startup is projecting $1B in revenue by the end of 2026, and is already closing in on $250M in ARR, @amasad says. Replit announced $150M in ARR just a few weeks ago.

Wrapping up my first week at @Replit with tons of great demos today at the Stripe x Replit x SV Angel hackathon. Truly incredible the apps (and honestly whole potential companies) that folks have built in just a few hours! Excited to help shape this incredible product - thanks to @jordwalke @pirroh @theandytee @amasad and team for bringing me on!

Slowly, then all at once 🥉 Replit has become the tool of choice for every builder, from startups to large enterprises. Thanks for your trust 🙏
🚨 Introducing the AI Apps 50: Startup Edition Ever wondered how startups are spending their money when it comes to AI? Our team at @a16z worked with @mercury to crunch the numbers and rank the top applications by spend. The list + what we learned from it👇
At every new model release, I begin to wonder what will come next for Replit Agent. Of one thing I'm sure, though. The next 12 months will be transformative. @AnthropicAI 🤝 @Replit anthropic.com/news/claude-so…

We tested Claude Sonnet 4.5 before launch, and I was really impressed by how far it will help us push autonomy on Agent 3. Even just 6 months ago, generating reliable code edits was considered a hard problem for LLMs. Not anymore ↓

The most powerful coding model, right at the core of Replit Agent 3. Just rolled out to all our users! ↓🧵

Great to see this launch! My experience and conclusions over the last year as a Replit power user: - The @Replit team listens. - They take people's feedback seriously (in fact they encourage it highly) - They ship fast - They have a strong foundation they are building from Thanks @pirroh and team for pushing forward on innovation and responding to shifts in the industry and community need.
You asked for more control. We immediately went back to the whiteboard and created 4 different autonomy levels for Agent 3. Depending on what you are building, pick and choose whatever makes you the most productive.

48hrs from our most important launch, I’m about to address the entire company on the All Hands meeting. It won’t be easy to convey all my gratitude while standing in front of everyone. So I decided to post it in public. Thanks @Replit. I love you all ❤️

AI agents can prototype apps… But shipping real software takes hours of testing, debugging, and refactoring. Agent 3 is 10× more autonomous — it keeps going where others get stuck. The “Full Self-Driving” moment of software.

We have been working hard on something exciting- designed to change the way you build 🤫 Sign up for the livestream below to learn more 👀
Continuing with my tradition of sharing alpha in public right before a launch. I locked in everyone at Replit on that technical roadmap for months. Just few more days until we 🚀
