Elon’s famous analogy: “Every person in your company is a vector. Your progress is determined by the sum of all vectors”. At big companies, vectors often point to different directions. The sum is zero. xAI has a small team of engineers, but every vector points at the same…


Codex is 🔥

Codex had its strongest growth in one day yesterday since the launch of gpt-5-codex. Way to motivate the team during a gnarly investigation that's making us go through every piece of infra, hardware and line of code in our system.



Sounds right

Have a friend who works at Nvidia. He phrased it nicer, but internally they think banks can fire most of their employees.



The brain is amazing

I agree w most of @karpathy’s assessments. Noone who actually spent time to learn neuroscience is not humbled by the complexity, intricacies, depth, & ingenious design by nature and had illusion that AI today was anywhere near a true comparison.



Yep

AgentKit and Codex are the same product. It's just a difference in form factor.



Yep

There’s never been a better time to be a creative technologist



Yes!

Every company needs a DM POC - someone high up who you can just DM the most obvious things and who shortcuts the PM hierarchy.



Sonnet 4.5

Introducing Claude Sonnet 4.5—the best coding model in the world. It's the strongest model for building complex agents. It's the best model at using computers. And it shows substantial gains on tests of reasoning and math.

Yep

For anyone out there, saying that MacBook are not good enough for local inference 🚀



Finally! Auto-compact!

gpt-5-codex is now available in the API + 0.40 CLI release: visibility into rate limits under /status, new /review features, auto-compaction and other small improvements



Are the Vikings good or bad this year?


Bad agents

Wow!!

Introducing Grok 4 Fast, a multimodal reasoning model with a 2M context window that sets a new standard for cost-efficient intelligence. Available for free on grok.com, grok.x.com, iOS and Android apps, and OpenRouter. x.ai/news/grok-4-fa…



It is amazing.

I’m surprised Apple got away with making everyone’s app icon logos blurry.



Claude has memory now

Excited to begin the rollout of this feature. I've found memory to be incredibly valuable when working with Claude. Starting with Team and Enterprise but coming to other plans soon.



Wut

I was talking with my bro about how he uses Claude Code, and realized he was operating the agents without a radar view. That's just silly
