[@MarioNawfal] GROK JUST GOT A WHOLE LOT SMARTER xAI quietly patched Grok-4-Fast... and the before/after is wild. “Reasoning” mode jumped from 77.5% to 94.1% complete responses. “Non-reasoning”? Up to a staggering 97.9%. All thanks to one thing: better injected system prompts. No press”

“Nice [@jeffreyweichsel] Can anyone beat this pun by @Grok? @SpaceX and @xAI are launching data centers into orbit… because why settle for cloud computing when you can have @X-traterrestrial computing?”

“🎶 Everyday we shufflin 🤣🤣 🎶 https://t.co/ym3El7FDvE [@amXFreeze] The GROK 4 you're using today is actually smarter than it was on launch day xAI didn’t just release it and stop.. they’ve been quietly upgrading GROK 4 under the hood...

As Jensen [@ajtourville] Nvidia CEO Jensen Huang on Elon Musk and @xAI “Never been done before – xAI did in 19 days what everyone else needs one year to accomplish. That is superhuman – There's only one person in the world who could do that – Elon Musk is singular in his understanding of engineering.””

“Coming out soon [@mark_k] "Grok Computer" coming from @xai Supposedly a computer-use agent? That's my guess. So basically like a taste of Macrohard. 🔥🔥”

“As this situation illustrates, we even do dumb stuff to ourselves 🤦‍♂️ [@techdevnotes] The @grok account is No Longer Affiliated with xAI And went from Gold check → Blue check”

“Best part is no part @Grok [@mark_k] Biggest difference when coding with GROK 4 by @xai compared to Claude 4 or GPT-5: Claude and GPT-5 are eager, producing more code for UI embellishments or extra features. Grok 4 is minimalistic, generating exactly what you specify. This is better in the long run.”

“Super important for civilization [@cb_doge] Why Elon Musk and xAI are building Grokipedia? Wikipedia has been hijacked by leftist activists. It no longer represents neutral knowledge, but propaganda. What was once a trusted source of truth has become a machine for biased narratives. That’s why xAI is creating Grokipedia,”

“It is often two steps forward, one step back, but we are making rapid progress in showing people compelling content. It’s too much in flux right now, but, hopefully by next month, we should be able to open source literally all of the @X codebase. Nothing left out at all. [@Scobleizer] The vibes are shifting here on X. Been talking to some on the inside of xAI. The new fully-completed algorithm is still a few weeks off, I hear. It will be run by a new Grok, and the report below makes me excited about the future. As they turn on new systems the vibes here… https://x.com/i/web/status/1996851528259588447”
