Feeling there’s some shade here from Claude that’s direct feedback for the dev team @AnthropicAI @claudeai 😀 These tool defs could use some work in voice chat!

@KaiXCreator Word. I’d add: Evolving the system after the first MVP in a way that aligns with your adoptive audience.

Hot take: Most people who say “AI will replace developers” have never built a real product. Writing code is the easy part. The real job is: 1. Understanding the problem 2. Designing the system 3. Debugging weird issues 4. Making things actually work in production

Welcome home Reid, Victor, Christina, and Jeremy! 🫶 The Artemis II astronauts have splashed down at 8:07pm ET (0007 UTC April 11), bringing their historic 10-day mission around the Moon to an end.

Artemis! 38 mins to splashdown!Watching the reentry with excitement - crazy that they’re traveling at 16,000 Miles per hour! youtube.com/live/nfhDuOHMp…

Interesting. I mean I'd frame this as "Chinese open source AI models are increasingly showing up in production at major US companies." but interesting...

Disturbing situation. I'm feeling good that we're quite conservative on our AI supply chain, as it were, and this warrants more digging to ensure we can trace provenance...

@karpathy @kepano What’s interesting is that I noticed that it is still a default library getting installed and used even by Claude desktop…it’s definitely lightweight and fast but IBM’s docling might work better in a heavy duty doc…

@kepano I just tried it this morning on the 245-page Mythos pdf and it failed badly and the outputs were all mangled. Converting pdfs is really hard, I think it has to probably be a Skill not a program, for a SOTA LLM for it to work properly.

I wrote about Microsoft's Markitdown back in 2024, but it's grown into a big messy project now :/ It would be more valuable if Microsoft provided high-quality official libraries for converting their proprietary formats to Markdown (.docx, .xlsx, .pptx, OneNote, etc). For now Obsidian's Markdown conversion options are: 1. Obsidian Web Clipper for converting URLs 2. Obsidian Importer for converting from apps like Notion, Apple Notes, Google Keep, Microsoft OneNote, Evernote, etc

@SanicaCodeio PHP.

Name a programming language you will never recommend to people

Strong release! GLM-5.1 is a DeepSeek-V3.2-like architecture (including MLA and DeepSeek Sparse Attention) but with more layers. And the benchmarks look better throughout! Looks like THE flagship open-weight model now.

@rxhit05 Can you call yourself a CEO if your company built a product and you had little do with it? Oh wait, that's most of them right there...carry on...

Can you call yourself a founder if your entire product was built by Claude?

@KaiXCreator max_tokens

I'm a vibe coder, scare me with one word.

@karpathy I think it doesn't help that every "influencer" out here is busy amplifying random AI signals, whether it makes sense or not. Asimov's prescient remark about "my ignorance is as good as your knowledge" comes to mind...

Judging by my tl there is a growing gap in understanding of AI capability. The first issue I think is around recency and tier of use. I think a lot of people tried the free tier of ChatGPT somewhere last year and allowed it to inform their views on AI a little too much. This is a group of reactions laughing at various quirks of the models, hallucinations, etc. Yes I also saw the viral videos of OpenAI's Advanced Voice mode fumbling simple queries like "should I drive or walk to the carwash". The thing is that these free and old/deprecated models don't reflect the capability in the latest round of state of the art agentic models of this year, especially OpenAI Codex and Claude Code. But that brings me to the second issue. Even if people paid $200/month to use the state of the art models, a lot of the capabilities are relatively "peaky" in highly technical areas. Typical queries around search, writing, advice, etc. are *not* the domain that has made the most noticeable and dramatic strides in capability. Partly, this is due to the technical details of reinforcement learning and its use of verifiable rewards. But partly, it's also because these use cases are not sufficiently prioritized by the companies in their hillclimbing because they don't lead to as much $$$ value. The goldmines are elsewhere, and the focus comes along. So that brings me to the second group of people, who *both* 1) pay for and use the state of the art frontier agentic models (OpenAI Codex / Claude Code) and 2) do so professionally in technical domains like programming, math and research. This group of people is subject to the highest amount of "AI Psychosis" because the recent improvements in these domains as of this year have been nothing short of staggering. When you hand a computer terminal to one of these models, you can now watch them melt programming problems that you'd normally expect to take days/weeks of work. It's this second group of people that assigns a much greater gravity to the capabilities, their slope, and various cyber-related repercussions. TLDR the people in these two groups are speaking past each other. It really is simultaneously the case that OpenAI's free and I think slightly orphaned (?) "Advanced Voice Mode" will fumble the dumbest questions in your Instagram's reels and *at the same time*, OpenAI's highest-tier and paid Codex model will go off for 1 hour to coherently restructure an entire code base, or find and exploit vulnerabilities in computer systems. This part really works and has made dramatic strides because 2 properties: 1) these domains offer explicit reward functions that are verifiable meaning they are easily amenable to reinforcement learning training (e.g. unit tests passed yes or no, in contrast to writing, which is much harder to explicitly judge), but also 2) they are a lot more valuable in b2b settings, meaning that the biggest fraction of the team is focused on improving them. So here we are.

You can now run Cursor on any machine and control it from anywhere. Kick off agents from your phone to run on your devbox.

@SaraDiscovers Just now

Do you write notes while coding?

@KaiXCreator 👋🏾🖖🏾

X is cool. But it’s 100x better when you connect with people who actually build. If you're into tech, AI, or coding, say hi 👋

@om_patel5 @Scobleizer That’s both dope and a mindf*ck but now I want to go set this up lol.

THIS GUY GOT TIRED OF MANAGING AI AGENTS THROUGH TERMINALS AND DASHBOARDS SO HE BUILT THEM AN RPG WORLD 5 agents and each one has a pixel character, a station, and they actually walk around the space when enough unresolved issues pile up, the agents walk to a meeting point and hold a council session. four different models debating what to do next, not scripted. each one reads the live system state independently. in one session an agent pushed for cold outreach to close leads at 2am. another one said that's a terrible look for an autonomous system contacting strangers while the operator sleeps. they ended up pivoting to an inbound strategy that none of them originally proposed. single HTML file, node bridge, and phaser. runs on a Mac Mini. instead of reading logs and checking dashboards you just watch your little pixel agents walk around and talk to each other this is the most creative way i've seen anyone manage AI agents so far

I look at this sticker on my old Linux rig on which I wrote nearly a million lines of code and it just hits differently now with AI code gen and being more of an AI pilot/architect. Doesn’t feel the same for sure but the coffee is still being drunk!

@sarah_edo Congrats, Sarah - and l look forward to all the great stuff you will almost definitely ship! (Yes, I just got back on this platform - the marketing guys insist...)

📣 After nearly 5 fulfilling years leading Core infrastructure organizations for Google, I’m thrilled to share that I’ve taken on a new role! I’m going back to IC work as a Distinguished Engineer- my new role is in Chrome as Area Tech Lead, AI Web Ecosystem! 💥 The rise of AI is driving a fundamental sea change in web architecture. While this era promises immense innovation, it demands rigorous focus on security, privacy, and user observability. AI is a technology. It must be integrated with the same deliberate care as the major technological shifts that preceded it. In this new role, I’ll be working alongside world-class colleagues to redefine the web platform for an AI-first runtime. My mission is to architect a composable web that enables safe, standardized, and mutually beneficial interactions between creators, users, and AI agents. With this transition, I am moving from leading large organizations back to the IC track. I’ve swung this "managerial pendulum" several times in my career, and I’m energized to return to deep technical work at a moment that so clearly demands it. I'm also excited to be working with/for web legends like @laparisa @jimbankoski @paul_irish @RickByers @Paul_Kinlan @groby @mathias @bmeurer @fractorious and so many more! 💥

Honestly the level of work you're doing with Vercel - especially the open-source AI SDK, the new AI gateway and the absolute killer app that VZero is - amazing. The next 12 months are going to be interesting as more companies scale with the token economy and I'm betting Vercel does well!

@SylonZero 🫡 we just helped a large customer with a pretty catastrophic issue on Vertex fail over

AI Gateway is quite literally a “peace of mind” product: ✅ No downtime ✅ No lock-in ✅ No keys 🆕 No training
