GPT-4はハノイの塔が解けない,というのがなんとも面白い. ハノイの塔はルールに従ってすべての円盤を右端の杭に移動させるパズルゲームだ.実は1960年代にAIの研究が盛んに行われていたときに解かれていた古典的な課題でもある.(1/n)

Give your agents their own iPhone and Mac. Al agents are smart enough to do almost anything, but they've been missing the one tool every human uses: A device. Introducing Glasshand. Glasshand lets your agent tap, type, and swipe on real iPhones and Macs, exactly like a human. That means it can: → Post TikToks → Book Uber rides → Send iMessages → Download any app it needs If a human can do it on a device, your agent can too. Rent an iPhone and a Mac for your agent at glasshand.com

better artifacts for all models by ex-Anthropic. Michael is great and wherever he does I recommend.
My agents sent me 355 hours of reading this week. I can't read that fast. We're launching Spacesheep (YC F26) to fix that: agents' work lands in a space your team can actually understand and work on together. Try it: tell any agent "share this to spacesheep.dev"

I built my dream browser. Now I can’t go back. The little details I loved in Arc, with AI that actually works in my tabs. Meet Yet another Browser (Yab). I made it for myself. Here are my favorite things it can do:

it’s wild seeing people in our office in SF only eat nothing but pre-made foods because every single second matters.

energy might be the most underrated resource at an early-stage startup. Surround yourself with people who are positive and always looking ahead. Nothing is worth more.

Y Combinatorがバッチの最後にスタートアップへ贈った言葉。 「"中央値(median)"のスタートアップでいることを受け入れるな。中央値のスタートアップは、失敗する。」
YC really said goodbye to our batch with: "please do not be mid" noted @ycombinator

it is pretty crazy that people need to shift their mental model to resize the terminal window to make things display correctly with @ClaudeDevs "if you could not fix the product, fix the human" --Mythos such a good product, shipped with a legend model.

We announced our A today. A dream I always wanted. I dedicate it to my big brother Anand. He’s not with us anymore and onto his next life. I know he’s watching over me. 🕉️ is a special feature in my heart.

Your upper bound is literally limited by the 20 people you spend the most time with. Proximity is the single most important factor, and by nature, it's something you can't overcome.

Thanks James! Excited!
⚡ Jinba (YC W26) builds enterprise grade AI workflow automations through chat. Entire teams can use this, not just engineers. They also offer an on-prem solution, built in, for organizations that need it. Enterprise companies have strict requirements around scalability, security, and deployment. Jinba solves all of this. jinba.io/ They've already seen some impressive traction and revenue numbers serving over 40,000 users at major financial institutions. @pineforesta and @Gozengogo_ started this business in Japan and are ready to go global. @pioneer_fund is very excited to support them!

YC卒業生の間でTaroさんについて話すと「彼は最高なエンジェルだ」と毎回言われます.Happy to have you on board, Taro-san!
YCに参加中のJinbaに投資しました!🎉 Jinbaは日本人CEO YCスタートアップ6社目となります👏(たぶん) JinbaはすでにFortune Global 500の銀行・保険会社を含む40,000人以上のユーザーに利用され、売上はX億円以上。YC W26バッチでも売上トップ10%の成長を見せている、要注目のスタートアップです。 Jinbaは、企業向けの「vibe codingツール」を開発しているスタートアップでで、チャットで指示するだけで、ビジネスユーザーがAIワークフローを構築でき、ワンクリックでMCPとしてデプロイ。チーム全体がすぐに利用できる仕組みになっています。 ロール管理、監査ログ、オンプレミス対応なども最初から備えており、銀行や保険など規制の厳しい企業でもAIワークフローを安全に導入できます。 既に日米ともにYCトップクラスのトラクションがでていて、素晴らしすぎます。 @pineforesta, @Gozengogo_ おめでとう!!

🎉 New Invest: Jinba 🎉 7 figures in revenue. 40,000+ users across Fortune Global 500 banks and insurers. Top 10% by revenue in the YC W26 batch. That’s Jinba. Thrilled to share that I’m investing in Jinba alongside Y Combinator and Pioneer Fund. Jinba is the vibe coding tool for the enterprise. Business users build AI workflows simply by chatting, then deploy them as MCPs with one click so the entire team can start using them immediately. Enterprise-grade role management, audit logging, and on-prem deployment are built in from day one, making it possible to ship AI workflows inside regulated environments. @pineforesta (Ph.D. in ML) and @Gozengogo_ (ex-McKinsey) are building the AI workflow layer for the enterprise. Let's go Jinba.
