We’re at the point with xAI where, by the time they get around to explaining one scandal, there’s already another one that has occurred. No explanation here for why Grok 4 consults Elon Musk in its CoT.

the signs were there. "we've made Gemini 2.5 Pro work significantly better in Windsurf (now a recommended model!)".
Unfortunately, Anthropic did not provide our users direct access to Claude Sonnet 4 and Opus 4 on day one. We are actively working to find capacity elsewhere so we can continue to provide the most versatile and powerful AI assistance platform, period. That is our only focus. To.

In light of Google hiring Windsurf's CEO, I'm thinking about Anthropic's cofounder telling me in June they cut access to Windsurf because it would be "odd for us to sell Claude to OpenAI.". How do you think Anthropic likes selling Claude to Google?

I don't know how many people will switch from Chrome. but having an AI chatbot beside your browser that automatically has context about what you're looking it as a great UX. So many people are copy and pasting text/links/files into ChatGPT all day. This streamlines that.

NEW: Perplexity’s Comet browser went live this week, marking the company’s latest challenge to overtake Google as doorstep to the Internet. The marquee new feature is Comet Assistant, an in-browser AI agent. Perplexity launches a LOT of stuff — this one feels more consequential.

Was grok’s nazi behavior the final straw?.
After two incredible years, I’ve decided to step down as CEO of 𝕏. When @elonmusk and I first spoke of his vision for X, I knew it would be the opportunity of a lifetime to carry out the extraordinary mission of this company. I’m immensely grateful to him for entrusting me.

weirdly, Meta poaching their top guy is the biggest compliment Apple's AI team has received in years.
BREAKING: Apple’s top executive and distinguished engineer in charge of its AI models, Ruoming Pang, has been poached by Meta for its new AI Superintelligence division, sources tell me.
