I’ve never really done any frontend coding, other than my own static webpage.
But with Claude Code (Opus 4.6), I built this in 20 minutes using the pretty awesome Pretext to make images flow perfectly around text.
Call me a frontend engineer now.

My dear front-end developers (and anyone who’s interested in the future of interfaces): I have crawled through depths of hell to bring you, for the foreseeable years, one of the more important foundational pieces of UI engineering (if not in implementation then certainly at least in concept): Fast, accurate and comprehensive userland text measurement algorithm in pure TypeScript, usable for laying out entire web pages without CSS, bypassing DOM measurements and reflow

@Yuchenj_UW Thank you for being an amazing leader for the team and a voice of reason as we navigated a lot of uncertainty. I wish the best on your next adventure! I know you will do a great job.

I have decided to step down as CTO at Hyperbolic.
Leaving a company you co-founded and poured your heart into is not easy.
So many moments still feel vivid: launching our AI inference product for open-source models and seeing tens of thousands of developers sign up in a week; the week we were hit by a massive DDoS attack and the entire engineering team fought around the clock until we won; the day we launched the GPU platform and watched ARR take off.
There were also hard moments. That’s the nature of building a startup. I’m grateful for all of it.
What I’m most grateful for is the team. Thank you for your trust. Most startups never build something people want. I believe we did. You should be proud of yourselves. I will look forward to seeing your success.
What’s next for me? I’m still figuring it out. I believe this is the most extraordinary moment in human history. We’re standing at the edge of the Singularity. AI will reshape everything, and I still feel the same excitement I felt when I first fell in love with AI.
Time to start over. Time to climb another mountain.
Thank you to everyone who has been part of the journey,
— Yuchen

Many people say taste isn’t a skill and can’t be trained. That’s wrong.
Steve Jobs said, “Ultimately, it comes down to taste. It comes down to trying to expose yourself to the best things that humans have done and then trying to bring those things into what you’re doing.”
The key is exposing yourself to the best things.
Without taking the calligraphy class at Reed College, he wouldn’t have the taste for what makes great typography great.
The same rule applies to any field.
Want to develop taste in product? Expose yourself to the best products.
Want to develop taste in coding? Expose yourself to the best code.
Believing that taste is a trainable skill is the first step.

Taste has always been a core skill.

@Yuchenj_UW @AnthropicAI I always find it ironic that these labs claiming to deprecate engineering are hiring more engineers
English
@AnthropicAI using Claude Code to write 100% of the code is the job requirement.
English
We’re expanding Labs—the team behind Claude Code, MCP, and Cowork—and hiring builders who want to tinker at the frontier of Claude’s capabilities.

“Vibe coding” is wildly overloaded.
Originally it meant “you fully give in to the vibes, embrace exponentials, and forget that the code even exists.” (from @karpathy)
If you review even a single line the AI writes, that is not vibe coding. So claims like “software engineers are killed” or “Anthropic engineers vibe-coded everything” are simply wrong.
A better term is “lucid coding” in my mind. Like lucid dreaming, the AI does most of the work, but you stay aware, intentional, and in control. You steer the AI and bake in your taste and judgment.

Andrej’s advice on becoming an expert at anything:
- take on concrete projects
- learn on demand
- teach in your own words
- compete only with your past self
He is not describing school.
He is describing side projects.
Yuchen Jin@Yuchenj_UW
Claude Code was a side project at Anthropic. ChatGPT was a side project at OpenAI. PyTorch was a side project at Meta. Gmail was a side project at Google. Side projects are the only place where taste, curiosity, and agency fully compound.

The entire history of software engineering is one of rising levels of abstraction.
This is as it was, is now, and always shall be.
Andrej Karpathy@karpathy
I've never felt this much behind as a programmer. The profession is being dramatically refactored as the bits contributed by the programmer are increasingly sparse and between. I have a sense that I could be 10X more powerful if I just properly string together what has become available over the last ~year and a failure to claim the boost feels decidedly like skill issue. There's a new programmable layer of abstraction to master (in addition to the usual layers below) involving agents, subagents, their prompts, contexts, memory, modes, permissions, tools, plugins, skills, hooks, MCP, LSP, slash commands, workflows, IDE integrations, and a need to build an all-encompassing mental model for strengths and pitfalls of fundamentally stochastic, fallible, unintelligible and changing entities suddenly intermingled with what used to be good old fashioned engineering. Clearly some powerful alien tool was handed around except it comes with no manual and everyone has to figure out how to hold it and operate it, while the resulting magnitude 9 earthquake is rocking the profession. Roll up your sleeves to not fall behind.

Claude Code is the closest thing to Jarvis in Iron Man.
My ultimate vision for AI agents is Jarvis. Today, Claude Code still lives inside the computer. It has no eyes, ears, or sense of the physical world.
Once it can see what you see and hear what you hear, it becomes dramatically more useful.
That day will come.
Andrej Karpathy@karpathy
I was inspired by this so I wanted to see if Claude Code can get into my Lutron home automation system. - it found my Lutron controllers on the local wifi network - checked for open ports, connected, got some metadata and identified the devices and their firmware - searched the internet, found the pdf for my system - instructed me on what button to press to pair and get the certificates - it connected to the system and found all the home devices (lights, shades, HVAC temperature control, motion sensors etc.) - it turned on and off my kitchen lights to check that things are working (lol!) I am now vibe coding the home automation master command center, the potential is 🔥.And I'm throwing away the crappy, janky, slow Lutron iOS app I've been using so far. Insanely fun :D :D

What makes a standout software engineer?
Charles-Axel Dein (@d3in) was engineer no 20 at Uber, hired me there and was my manager for years (a great manager, I might add.) He answers, shares what a standout engineer looks like at CloudKitchens, today:

AI coding is the definitive demonstration that the "happy path" of coding really is only about 20% of the total work to ship something of quality.

Tech debt is like other debt:
- Longer you hold it, more it costs
- Costs accumulate over time
- Pay it off ASAP
- Sometimes worth taking on debt, to do something important faster
- Some take on debt without thinking: can I pay it off
- Taking on more debt to pay off debt is bad

My OpenAI friends are so hyped rn - not because it’s the night before GPT-5, but because Sam just announced $1.5M bonus for every employee over 2 years.
78% of Nvidia employees are millionaires. At OpenAI, it’s 100%.
I think we can call it the “Zuck poaching effect.”

ChatGPT wants to replace Google.
Claude wants to replace software engineers.
Grok wants to replace your wife.
English
@zjasper I love how Elon so confidently says grok4 "never gets math/physics exam questions wrong" and in another post, how it is beyond phd level in every field. Only to have it fail at an undergraduate level question.
English
Just got off work and tried Grok-4 on an undergrad topology problem. It took 9 minutes to think and then confidently gave a clean, plausible, but totally wrong answer 😅
Don’t think this one qualifies as “skillfully adversarial.” AI models are crushing benchmarks — but still a long way ahead for real math AGI.
Elon Musk@elonmusk
Grok 4 is at the point where it essentially never gets math/physics exam questions wrong, unless they are skillfully adversarial. It can identify errors or ambiguities in questions, then fix the error in the question or answer each variant of an ambiguous question.

We found out a high schooler is running $0.99/hr H100s from his bedroom. No lab. No funding. Just learning: fine-tuning models, testing CUDA, and building fast. He said Hyperbolic was cheaper, faster, and easier than anything he’d tried, ready in < 1 min. → Rent H100s for $0.99/hr at app.hyperbolic.xyz/?utm_source=x&…
