> Imagine what happens when millions more people can build robots, medical devices, instruments, vehicles, satellites, toys, tools and things none of us have thought of yet. More builders is more better!
The walls between engineering disciplines are coming down. And when they do, millions more people will be able to turn ideas into physical products. We took a big step toward that future today 🚀

CAD is about to collapse into one interface

For years I've been telling people that Flux is taking the hard out of hardware. When we started, that mostly meant PCBs. But that was never the destination. The dream was always much bigger: what if

y’all @CommandCodeAI has massive capacity for Kimi K3. And sub starts at just $1 Go with 10x free credits. New? Command Code is purpose built for open models. Tool repairs, cache repairs, and phenomenal harness engineering. Currently #1 coding agent harness on OpenRouter.
Kimi K3 has received far more love than we expected, and our GPUs are feeling it. Over the past 48 hours, demand has pushed close to the limits of our current capacity. To protect the experience of existing subscribers, we're temporarily pausing new subscriptions and prioritizing compute for current members. Existing subscribed users are not affected. We're adding capacity as fast as we can and will reopen new subscription spots in batches. Going forward, we'll also split membership into two more focused plans: Kimi Membership for Kimi Web, App, and Work; and Kimi Code Membership for coding workflows. This will help us match compute more precisely and keep the experience stable. Thank you for your patience and understanding!

Command Code just crossed 15K paying customers! 🥳 It took us 60 days to get here. 3T tokens. We added yet another $1M a month, and now doing $2M run rate!! July will be crazy, GUI, SDK, ACP, v1 GA, BYOK, major new plan, and two new products launching. Command Code is quickly become the best most used coding agent harness for top open and closed models. We took an early bet on open models when all other agents were only focused on closed frontier models. Our research has led to the discoveries and meaningful inference engine improvements like: 1. tool call repairs (make open models faster and outperform closed by improving their tool calling ability, now doing 1M repairs per 1T tokens on most open models) 2. /design skill (a super well researched bundled skill built by real designers which is an easiest way to deslop AI's design "design repair" and improve just about any design surface) 3. cache thrashing repairs (saving tens of thousands of dollars in costs to our customers with 97-98% median cache across the top 5 models, gateway fallbacks are a bad idea, most gateways are costing you money, strong prefix building and cache management can lead to massive infra/cost improvments) … and a couple of amazing new things we're cooking, about to launch this month! We're also hoping that alongside v1 launch we'll be able to open source Command Code, and make it fully hackable, extendable, and support BYOK, with Codex, Claude, Grok, and more subscriptions working natively. Super easy to get started with $1 Go plan with 10x credits, literally $10, extends to $40 on DeepSeek and other deals as we're not overcharging like all our competitors. Massive roadmap ahead, thank you for all y'all's support. Let's go! 👊

Ona (formerly Gitpod) is joining @OpenAI, bringing their secure cloud execution and async agent orchestration tech to further enhance Codex! Five years ago, I sent @jolandgraf a DM on Twitter after seeing how rad Gitpod was for spinning up cloud development environments. It seemed clear to me that devs needed better ways to manage multiple environments for different projects, especially in the enterprise. I made my first angel investment in 2021. As I got to know Johannes better, I realized what a special founder he is. Always asking the hard questions of himself and his team. Relentlessly pursuing product/market fit. Extensive communication to the team and investors through Notion docs. In 2022, I led their Series A at @PWVentures, a first for me, and one of the biggest checks I've written to a startup. Over the last four years, Johannes and team have been through several mini-pivots, always adjusting to the market. As AI has taken over mindshare, they made their biggest pivot yet, rebranding and leveraging their core tech to bring robust AI tooling/orchestration via secure cloud development environments to the enterprise. Ona's technology is years ahead of competition, and I'm really glad to see it land at OpenAI, where millions of devs will get to experience it make their lives better. Congratulations to @jolandgraf and the whole Ona team—a well deserved success, and a bright future for you and the product!

I got a new MacBook Pro recently and the trackpad is being weird: When I two-finger scroll, stop, then release my fingers to scroll again, the content I'm scrolling will occasionally jump (like a phantom scroll input). Sometimes a little, sometimes a lot. Never once had this problem on my previous MacBook Air. Anyone seen this? Can't find anyone else on the web with this problem. It's killing me!

It turns out that if you fix tool calling and add a taste layer on top of open models, you can get really good performance for very low cost. @CommandCodeAI is how you do it. Save money. Code more. I predict we'll all be using open models before long.
BIG day for us!! @CommandCodeAI has crossed $1M in annual run rate, 1 trillion tokens of usage, with over 9K customers, just 24 days after our public beta launch. we believe this makes it the fastest-growing coding agent harness for open models. 3rd largest by usage. Command Code is built around two ideas: 1. open models should be production-grade for coding. 2. your coding agent should learn your taste. we're building for taste and developer experience. so instead of making a soup of thousands of models, we build for the best ones, open or closed. the goal: a coding agent that feels like an iphone, opinionated and with taste, not a random android or a windows phone with no taste. on the first idea: open models. we fixed the "open models aren't good enough at tool calling" problem. our research came down to two things, quality and speed, and both trace back to one root cause: broken tool-calls that open models produce, especially when you use a bad harness. open-model tool-call failures are not deep, they are a small finite set of contract mismatches. so we repair them, with zero token loss. what started as 4 repairs is now the largest repair layer in the space: 36k tool-call fix variants. i wrote the idea up openly¹ a few weeks ago, and it has quietly become a de facto way people fix open models. developers have either adopted Command Code or used the same idea to build repair harnesses for nearly every top coding agent. i take that as more meaningful validation than anything we could say about ourselves. on the second idea: taste. Command Code builds your coding taste into skills, learned from your accepts, rejects, edits, prompts, and the corrections you repeat. over time it drifts away from generic code and toward how you actually ship code. it learns continuously, and while it is early, the direction feels right. net effect: developers using Command are writing production-quality code on open models, 10x to 100x cheaper, without fighting tool calls, while building repo and team-wide coding taste that compounds. i believe these numbers are a consequence of getting those two things right. what's next. we've applied the same repair idea to ai design slop, and bundled a /design capability² so every developer can level up their design work. the early response has been great. we have a big roadmap ahead of us. the feedback we hear most is that Command Code feels fundamentally different: an approach built on taste and repair. we're going open source next month. today we're a cli at the core, and we're also launching a full-fledged gui app, sandboxed background agents, and cooking up something fun i can't wait to share. we're growing too, hiring in sf and remote worldwide. check open roles on my profile bio. try it now. npm i -g command-code if you like engineering deep dives on how we're doing all this, i've linked some relevant posts below.

I turned 47 years old yesterday, so it's time for my traditional reverse birthday present! This year, I'm sending 47 teenagers to Shenzhen, China (the electronics capital of the world) to build hardware at Hack Club's Fallout, our flagship electronics hackathon! Fallout is a free, in-person hackathon in Shenzhen by Hack Club open to teenagers ages 13–18. Participants spend one week designing, manufacturing, and assembling their own electronics at the source, visiting the legendary Huaqiangbei markets, touring PCB fabs, and shipping a finished hardware project by the end of the trip. I'm covering travel and build costs for the first 47 teenagers! To sign up, all you need to do is go to fallout.hackclub.com and start building. For example, heres a custom made expressive midi controller based on the stm32 ecosystem. Built by a 17 year old from NYC: github.com/udu3324/stm32pe-m… Now go build something cool!

My friends and I got tired of saying "agentic coding" all the time so now we just say "genting". As in, "sorry, I can't come to your party, I'm going to be genting all night." We started saying it ironically, because it sounds ridiculous, but now it just feels normal. LOL language. I'm curious what we will call "coders" in the future, when we no longer write any code. What do YOU say you're doing these days?
