there’s ~40% chance that xAI acquires Cursor. or at... least some sort of collaborative relation between them. Cursor has the goldmine. mountains of real world dev data, prompts, and codebase patterns from millions of AI-assisted coding sessions. xAI has Colossus. the largest GPU cluster on the planet. imagine the data + insane compute together, that’s disruption of peace for the three largest players. elon is a visionary. he sees it. Grok Code soon!show more

BREAKING: SPACEX IS BUYING ITS WAY INTO THE AI... CODING WAR FOR $60 BILLION. 🇺🇸 Musk's SpaceX agreed to acquire Anysphere, the company behind Cursor, in a $60,000,000,000 all-stock deal, days after its record Nasdaq IPO. Cursor competes directly with Anthropic's Claude Code and OpenAI's Codex. This deal hands xAI a foothold in a market where it was lagging, overnight. Revenue around $2,600,000,000 annualized. A $10,000,000,000 breakup fee shows how badly Musk wanted it. The AI coding race just went from a startup fight to a clash of trillion-dollar empires.show more

I’m joining OpenAI Codex to work on the future... of agentic development! At Cursor, I got to see the shift from autocomplete to agents. The next step isn’t a better IDE. It’s an Agent Development Environment (ADE): systems and tools for orchestrating agents, reasoning over their outputs, and making them autonomous enough to reliably complete ambitious work. After chatting with Alexander Embiricos and Tibo, it was clear that Codex is the best place to realize this vision. The team has consistently shipped SOTA models for agentic coding (check out gpt-5.3-codex) and I’m pumped for the future that the new Codex App points to. What I’m most excited about is the broader mission: accelerating the knowledge work economy. All agents are coding agents, and we’re already seeing Codex used across every job function within organizations. I’m extremely grateful for my time at Cursor, working with the incredible team, and I’m proud of what we built together. I’m excited to take an even bigger swing with Codex. If you’re curious to get a glimpse of where we are headed, download the Codex App! If you want to work on this mission, please apply or reach out - we are hiring across all functions! You can just build things.show more

2 Cursor Composer agents working together on the same... project. one builds the project, the other reviews once the first agent is done and writes a report. cursor rules file is in comment to achieve this. first agent is instructed to build the project second agent is instructed to write a monitoring script to determine when the project is done then to review the project for errors and write a report This prompt can be improved. This is meant as a baseline If you are interested in learning how to use Cursor more in depth, I have a 28 chapter 1000x Cursor Course building full apps from scratch with 19 hours of content. link is in my bio if you are interestedshow more

Why $30BN for Cursor Is A Good Deal: "The... pro side is revenue and revenue growth rate. If something's gone from $1-$100M in a year, and then $100M to $1BN this year, with Newton's laws of motion, it is going to $3BN-$4BN next year." Suddenly you're in this thing at 10 times NTM revenues." Legit question, when you do Cursor at $29BN, what do you underwrite to? Miles Clements Lucas Swisher Sarah Wang Tom Hulmeshow more

I think it's interesting that we're starting to see... different types of specialists emerge in the field of Generative AI technology. We are seeing a new generation of world-class storytellers. Some are immaculate at vibe coding workflows and building infrastructures. Some are incredible at AI visual effects and AI cinematography. And some are just maestros at composition and world-building. And of course, many of us dip into all facets. We are witnessing the emergence of new creative and technical roles that didn't exist yesterday, and that's very exciting. And now we are starting to see the benefits of AI as an additive to existing workflows. I hope to work with many of you for the upcoming productions we have in the works at Promise.show more

Fable 5 comes back！It can now build playable game... prototypes. I think it is actually a signal for where AI coding is going. Making a game is not just “write some code.” Even a small browser game needs: game loop；character movement；collision logic；scoring system；UI states；physics tuning；visual feedback；bug fixing；playtesting This is why game prototyping is a great test for AI models. A model cannot fake it with a pretty answer. Either the game runs, or it does not. What impressed me about Fable 5 is that it is useful for the messy middle: turning an idea into mechanics, turning mechanics into code, debugging broken interactions, and iterating until the prototype feels playable. But here is the practical part: I would not use the strongest model for every step. For game building, I would split the workflow: 1. Fable 5 for game design + architecture 2. a fast coding model for routine implementation 3. a vision-capable model for screenshot/UI feedback 4. a cheaper model for docs, test cases, and small fixes 5. fallback when latency, cost, or output quality becomes a problem That is the real AI coding stack. Not “one magic model does everything.” More like: the right model, for the right task, at the right cost, with fallback when things break. This is why I’ve been looking at ZenMux ZenMux. ZenMux gives developers one gateway to access multiple leading AI models, with OpenAI / Anthropic / Google Vertex compatible APIs, cost tracking, quality benchmarks, auto-routing, and compensation when output quality, latency, or throughput falls short. If AI can now make games, the next question is not just “which model is strongest?” It is:how do we manage the whole model workflow Fable 5 shows the creative ceiling. ZenMux is closer to the infrastructure layer you need when AI coding becomes a real production habit.show more
