Composer 2 is out! Cursor is an example of a new type of company, not a pure app maker and not a model provider. Our aim is to build the most useful coding agents by combining the best API models and our domain-specific models.

Composer 2 marks the one-year anniversary of our large model training efforts. Since then, we've built an exceptionally talent-dense team of ~40 people with some of the best researchers and engineers from the labs, academia, industry, and more heterogeneous backgrounds. And we are exclusively focused on coding. We don't care about models that can respond to emails, do your tax returns, or be your friend. Every FLOP, token, parameter, and researcher is entirely dedicated to software engineering.

don't bet against this team!

Today we’re launching the newest version of @paradigmai When we started Paradigm, the goal was never to tack AI onto existing spreadsheets. It was to build a new type of interface that does the work for you. Now we’re pushing that vision much further. Workflows turn Paradigm into a system that runs research processes for you. Connect your CRM, existing spreadsheets, Slack, email, and internal data, and let Paradigm continuously run the research workflows your team already does. Same intuitive interface. But now a system of action. If you tried Paradigm before, try it again. Manual research is now a competitive liability.

Update on this: - cursor & opus got the proof of concept working - gave it back to codex and said “hey this is working if you were to rearchitect from scratch what would you do” - full day of turns & refactors - bugbot snagging edge cases - shipped & Devin does docs

the answer was Cursor all along 😃 while we're messing about with our Claude Codes and Codex CLIs people that just kept using Cursor & optimized their workflows seem to be winning 🤦‍♂️ maybe it's my FOMO, but the other day I asked about which model to use between Opus 4.6 and Codex 5.3 People were like "use both". I'm thinking, how tf can I use Codex 5.3 in Claude Code and also not pay OpenAI 200 bucks too. Turns out most of them just use Cursor 🤷

@Bhavani_00007 multiple times, every day

Anyone still using Cursor?

GPT-5.3 Codex is now available in Cursor! It's noticeably faster than 5.2 and is now the preferred model for many of our engineers.

@mindtheflo @cursor_ai 100% agree!

Drives me nuts that @cursor_ai is so underrated at this point. I’ve spent the last week with Claude code, Codex, the new codex app and of course Conductor and can tell you know: night and day. Being on X, I felt I was missing on something. Well not at all. Turns out everyone is missing on Cursor. Here’s my top five: - Cursor with Opus 4.5 is unbeatable. Full stop. Even the native Claude code harness doesn’t come close. - Bug agent is so so SO good that I asked Cursor to create a skill I could use with Codex and Claude to get work done. Pure genius from the team here. - Cursor has made installing MCPs and Skills so easy that I didn’t realize how bad the others were until I tried. Who wants to waste 15 minutes figuring out the format of each agent and unique workflow to Oauth. - Cursor agents management is best in class (even though I’m impatiently waiting for them to create some sort of Kanban to track which work I’ve reviewed) - The UI is delightful to surface everything you need when you need it so you never have to search online how to do something. But it’s powerful enough that you can always go crazy when needed (sub agents, hooks, etc). I could go on and on talking about how they accidentally created one or maybe the best agentic browser. Then there is composer, by far the best way to work on UI side by side with an agent at light speed. Oh and let’s not forget Bugbot that is pretty much managing my whole QA and fixing things autonomously at this point. 🤯 So yep, I’m keeping my 3 ULTRA (likely need a 4th one this month) subscriptions. I hope they launch a generous 2K plan soon as this would feel cheap for running what feels like a team of 10 engineers in 2020. I love you @cursor_ai. @notis_ai would not be half the product it is without your work. You are my daily North Star when it comes to building a product that is 200$/month and yet look stupidly cheap. PS: thank you for shipping updates every day that delight me.

Introducing a new category of app: Your Daily Assistant Unlike other apps, @hero_assistant is the first daily assistant to run your life: 1) Brings your entire life into *one app* 2) Briefs you every morning with what you need to know 3) Tells you exactly what's coming up, with 'SuperAlerts' that take over your lock screen 4) And blocks social media when you have things to do Why? Because if you jump between apps all day, eventually you'll blow up 😉 👇 see the new way to live

🚀 Today is a big day: Mesh has officially secured a $75M Series C, bringing our valuation to $1B. 🦄 Fifteen years ago, I came to the United States with almost nothing, driven by belief, grit, and an obsession with building meaningful businesses. After years of endless nights, hard lessons, and selling my previous startup, I took the leap again six years ago and started Mesh. What began as a bold idea is now a $1B company, built alongside an extraordinary team, trusted partners, and world-class investors. This is more than a funding announcement–it’s the beginning of the end for legacy payments. For too long, global commerce has relied on systems designed decades ago: networks optimized for batch processing, delayed settlement, and geographic silos. Incumbents have locked commerce into closed networks, extracting high fees and limiting choice for merchants and consumers alike. That model worked for a while, but it doesn’t work today. At Mesh, we believe payments should be easy, instant, and interoperable by default. Any asset. Any chain. Any geography. Ultimately, today’s announcement is bigger than crypto. It’s about building a new financial system–one that actually works for everyone, not just those who profit from high friction. I want to thank our customers and partners, as well as the investors who participated in this Series C, including Dragonfly, who led the round, along with Paradigm, Moderne Ventures, Coinbase Ventures, SBI Investment, Liberty City Ventures, and others. Becoming a unicorn is not the finish line. It marks the end of the beginning. We are now stepping into our next chapter with momentum, setting out to build a generational business that defines the future of payments. Our next milestones are clear: $1B in revenue and $1T in volume.

This work by @cursor_ai is, I think, the coolest AI breakthrough since GPT-4. (And there are plenty of candidates!) simonwillison.net/2026/Jan/19/sc…

we just raised another $25M after 10x'ing our ARR in 5 months. the crazy part is this almost never happened. 17 years ago, I watched Iron Man as a 10-year-old kid in Delhi. that night, I pulled my first all-nighter teaching myself to code. not because I wanted to build apps or make money. because I wanted to build Jarvis. my parents gave me 1 hour of screen time per day. so I coded in secret, sleeping every alternate night through middle school and high school. built 50+ apps. got a cease and desist from Google at age 12. all for this one obsession: making computers understand us like humans do. fast forward to today: - we've raised $81M total to build the voice operating system - growing revenue 40% month-over-month this year - 70% user retention after one year (unheard of in consumer) - teams at 270 of the Fortune 500 use Wispr Flow daily our Series A2 was led by @hanstung at @notablecap (who was an early investor in five companies that made it to $100B valuation like Slack, Tiktok, and Airbnb). we also brought on @StevenBartlett as an investor and partner. but here's what matters more than the money: we cracked voice input. not transcription - actual understanding. our users hit "send" in under 0.5 seconds without checking. they trust it blindly. that's never existed before. in a recent benchmark, Wispr came out as 3-4x more accurate than OpenAI, ElevenLabs, and Siri. and we're just getting started. voice input was step one. now we're building the assistant that actually does things for you. to my co-founder @SahajGarg6 - there's no one else I'd rather build Jarvis with than my college roommate and closest friend. to our team pulling all-nighters and shipping magic - you're the reason that 10-year-old kid's dream is becoming real. we're hiring cracked engineers and growth marketers who want to build the future of human-computer interaction. the keyboard had a good 150-year run. time to build what comes next. PS: like, retweet, and bookmark to get wispr flow for free for 3 months ❤️ — Written with @WisprFlow

We’re excited to announce our partnership with @Samsung, bringing Net 60/90 payment terms* directly into the Samsung Business checkout experience. * Slope is a financial technology company, not a bank.

We've raised $2.3B in Series D funding from Accel, Andreessen Horowitz, Coatue, Thrive, Nvidia, and Google. We're also happy to share that Cursor has grown to over $1B in annualized revenue and now produces more code than any other agent in the world. This funding will allow us to invest deeply in research and build Cursor's next magical moment.

Thanks @RashiShrivast18 for telling the @speak story! We’re pushing hard to make the world’s best AI language tutor available to everyone. Super excited for the slate of new feature launches coming later this year! Stay tuned. forbes.com/sites/rashishr…

I’m very excited to announce AI Autocomplete AI Autocomplete is a breakthrough patented technology that supercharges natural language input = Unlocking 10x faster search and commerce, advertising, and powerful augmented reality. Available for use as an SDK. This solves a fundamental problem of today’s chat interfaces – They are good at single step request, but any multi-step action (like booking a flight or purchasing goods) quickly becomes a back and forth 'game of 10 questions'. While working on our own assistant, we realized the core driver of this problem is a human one: People don’t know everything they need to say upfront, for every action you could do on the internet. And to solve it, we would need to think about how to marry design and technology in a new way. AI Autocomplete solves this, and can now plug into chat interfaces to guide you in real-time, with everything you would need to say, upfront. So you can do anything you can do on the internet in one shot. No more back and forth. As a result, this unlocks multiple AI breakthroughs: 1. 10x faster search and commerce 2. Smarter (and far lower cost) media generation 3. Natural language advertising 4. Powerful, lightweight Augmented Reality From here, we’ll be using this for Hero, but we also want others to use it too since this is an industry-wide problem. So if you have a product that could benefit from AI Autocomplete and want to work with us, reach out below! Shoutout to @seunglee1b who helped think of and patent this nearly 3 years ago! And shoutout to the entire @hero_assistant team that keeps innovating on the next generation of AI products
