The new Codex model is available in Cursor! It's free to use until December 11th. We worked with OpenAI to optimize Cursor's agent harness for the model.

This year Kit passed $50M ARR. @danputt has been my coach for six years of that journey. In this episode, we cover: - How confidence makes a real difference - How to make hard decisions - Strategies that got us there Search "Nathan Barry Show" to watch.

Harvey has raised a $160M Series F, led by @a16z, with participation from @wndrco, @sequoia, @kleinerperkins, @conviction & @eladgil.

I’m hiring an Executive Software Engineer. Think of this like a Chief of Staff, but your job is to create technology that allows me to scale and move faster. You’ll work closely with me, my CoS, and the Valar IT/Security teams to rapidly create software and hardware tools under my direction. I'm looking for a general athlete, not a specialist. The more and weirder systems you've built with your own hands, the better; but you need to be well-versed in all the latest and greatest ways of creating things wicked fast (Vercel, Replit, AI coders, etc). You'll be responsible for everything, from front-end design to backend implementation, auth, hosting, maintenance, testing, planning, product ownership, etc. Most importantly you'll have the driver's seat view of and direct impact upon the most important company of our time, working with the greatest team of nuclear builders assembled since the Manhattan Project. You'll get the opportunity to work alongside elite operators executing at the top of their game and become one of them. If you are: - self directed - curious - addicted to solving hard problems - really really really good at making software tools very quickly Please send a portfolio, narrative, and evidence of exceptional ability to @CWNazarian.

What are you curious about? We’re not here to tell you what to build. But we do have a few questions, which is where great ideas start. Here’s what we’re most curious about, right now

40,000+ people signed up for Cursor community events in the past 6 months.

new from me on @every: opus 4.5 blew me away this week. i built fully featured reading companion app that i now use every day, in between meetings without looking at the code. two things that are important: - we just reached a new level of autonomous coding. you've been able to one-shot an impressive app demo for a while now with any frontier model. opus 4.5 is the first model that just keeps coding and coding without running into endless loops of errors. - prompt-native apps are now possible. opus 4.5 can now act as a general-purpose agent INSIDE your app, to power many of your features. this turns building features into an exercise in writing prompts—instead of writing code. it's the same paradigm claude code uses but now available for non-coding usecases. more on @every here: https://every.to/chain-of-thought/opus-4-5-collapsed-six-months-of-development-work-into-one-week…

Nice Google Search Console analysis with the new AI-powered configuration https://developers.google.com/search/blog/2025/12/ai-powered-configuration…

What tool are you using to make your Nano Banana Pro images?

Someone asked me, "Why do you think YC demo day is far better than most tech events?" Me: "It feels more like a reunion, with far fewer aggressive pitches and requests to connect on LinkedIn." FWIW, I respect the hustle, but feel drained by highly transactional social environments. That's why I rarely go to tech events.

We're expanding our partnership with @Snowflake in a multi-year, $200 million agreement. Claude is now available to more than 12,600 Snowflake customers, helping businesses to quickly and easily get accurate answers from their trusted enterprise data, while maintaining rigorous security standards.

We’re launching Anthropic Interviewer, a new tool to help us understand people’s perspectives on AI. It’s now available at http://claude.ai/interviewer for a week-long pilot.

Reviewing AI-generated code is the new bottleneck. Writing code was slow before. Now, in a few minutes, you can generate virtually unlimited lines of code using AI. But developers are now spending 70% of their time checking that code. That's the new bottleneck. I've been using Cline, and they have a feature that actually helps with this: You can click a button and have Cline generate an inline explanation for every single line of AI-generated code. Take a look at the attached video. What it does: 1. You can read the code and the explanation together 2. You don't lose context while reviewing code 3. You understand the "why" behind each change And here is the best part: It works on any git diff. You can use it to review PRs, understand commits from other people, or catch up on a codebase you haven't touched in a while.

(this is not ragebait, i promise, just read til the end) The "employment" concept is having its last decade. Salary alone can't make anyone work hard anymore. Tiny startups run by founders outcompete employee-run businesses. AI replaces junior/average work, while top talent freelances, productizes skills, or starts a business. All recent notable hires were - acquihires (Bun, Windsurf, Lemon Squeezy, and more) - bribe-hires (Marc paying huge signing bonuses to get people to join) The critics are gonna say, "but everyone can't be a businessman.." Well, go back to the early years of IG/YT. Only professionals were making videos and creating social media content. Today, half of the working population is doing blogging and other types of content creation. I think in the old days, "business" meant "i'm planning to raise money, build a unicorn, go for IPO...". But today the definition has changed. People would rather prefer making $30k/mo with their own biz instead of being employed. Just because it feels better and you get 100x more respect from society. E.g. when you go to a party and say "i work as .... in faang.." nobody really cares about you from that moment and on. But if you run a business that's barely making a living, people are interested. So the future key human KPI wll be this: "Be interesting". There are many ways to achieve it, but entrepreneurship will be one of the most popular. Long story short: no matter what you do, try your shots at building a business. Do it as a side gig, on weekends. Maybe it's not for you, fine, but give it a try, dont take risks, keep your job, just use your spare time. thx for coming to my ted talk.

do you agree?
