Built a fact-checker that pulls live data in seconds. @xAI's Live Search API gets news and X posts in one call. Game changer for @SecondOpinionSO.
Happy second birthday @xai
Announcing formation of @xAI to understand reality
In 1000 years archeologists will wonder how Andree & team built such colossal compute infrastructure so rapidly without legions of robots.
Our @xai Memphis team never ceases to amaze. Holy crap - setting records and establishing new baselines every day. LFG!!!
LinkedIn every day for the last two millennia:
It's a great day to send an email. ☀️
I will never understand the obsession with JSON+REST+Python/TS. Proto+gRPC+Rust/Go is much better. Our entire backend stack across API, Auth, Grok is based on it.
Atlassian switched from JSON to Protobuf for one of their services, resulting in: - 75% less memcached CPU usage - 80% smaller data - 33x faster deserialization - a 55% smaller memcached cluster
xAI gave us early access to Grok 4 - and the results are in. Grok 4 is now the leading AI model. We have run our full suite of benchmarks and Grok 4 achieves an Artificial Analysis Intelligence Index of 73, ahead of OpenAI o3 at 70, Google Gemini 2.5 Pro at 70, Anthropic Claude…
Go ham but don't trigger my pager. Model reliability is also reported on status.x.ai.
I have discovered a truly marvellous live stream link, which this post is too narrow to contain
Grok 2 happened less than a year ago. Tonight we'll unveil Grok 4.
sus
Grok 4 release livestream on Wednesday at 8pm PT @xAI
The data shown on status.x.ai is actually a live export of our internal dashboards. This means you can see in real-time when Pagerduty decides it's time for me to wake up.
This xAI status UI kinda hot man
Grinding on @Grok all night with the @xAI team. Good progress. Will be called Grok 4. Release just after July 4th. Needs one more big run for a specialized coding model.
Moats are dug with spoons. One big feature will attract attention. A thousand little features will create retention.
An EPIC day at the @XUK Client Council with @xai co-founder @TobyPhln Grateful for the team, grateful for the work, and the grateful for the packed house eager for what’s next at 𝕏. The future has arrived @X 🤝 @xai
In other news, today was my 2nd @xai anniversary. Not a single boring day (or night; xai never sleeps™) at this company.
To most users, the performance of a model on academic benchmarks is as important as the transistor count of their CPU. Yes, higher probably means better but in a way that is very much intangible and thus inconsequential to their product decisions.
Google Search is having its Internet Explorer moment. Regulators are coming for it just as strong competitors from younger companies are emerging. x.com/i/grok/share/c…
Preview of a new shader made by @XorDev. Needs just a few tweaks before we'll ship it.
