SOUTH KOREA IS COLLAPSING EVEN FASTER THAN JAPAN
South Korea now has the lowest fertility rate in the world — sitting at around 0.7 children per woman. That is less than half of the 2.1 replacement level needed to maintain a population.
The country is aging and shrinking at an
Tesla Owners Silicon Valley@teslaownersSV· 12. Juli 2026JAPAN IS QUIETLY DISAPPEARING
Japan’s birth rate has collapsed to record lows, and the consequences are no longer theoretical.
The fertility rate now sits around 1.2 children per woman — far below the 2.1 replacement level. The population has been shrinking for over a decade,

False. Proof of Citizenship and cleaning voter rolls would expose Michigan and she knows it.
Breitbart News@BreitbartNews· 11. Juli 2026Sen. Elissa Slotkin (D-MI) falsely claims the SAVE Act would "disenfranchise all married women... You'd have to show your birth certificate at the polls if you have a married name."

What she’s saying is such an utterly idiotic lie. Married women have to present ID all the time for everyday living!

@just_cameron The default in Grok Build is off. You can also run /privacy and any synced data is deleted. ZDR is respected for both headless and interactive use as well.

We're rolling out a small tweak to boost visibility of your posts to your mutuals (people who you follow back).
We noticed this data was missing from the algo and it made your friends appear less in your replies. This resulted in the reply section feeling more like a battleground with people you don't recognize.
This should also help clusters form around interests more easily, which many people have asked for.

That's not the case. The CLI doesn't retain data under ZDR (including headless/non-headless modes), and has since launch. Similarly, /privacy in the CLI will disable or reenable any data retention. For some features, including remote session listing, cloud agents, and handoff, you will need to enable data syncing.

True.
As a precautionary measure, all user data that was uploaded to SpaceXAI before now will be completely and utterly deleted. Zero anything whatsoever will remain.

ZDR and /privacy are always respected in Grok Build - and swapping your setting with /privacy deletes any synced data retoractively

SpaceX policy regarding data retention.
It is actually helpful for debugging issues if we can retain some amount of data, so allowing this would be appreciated, but your privacy settings are always respected.
SpaceXAI@SpaceXAI· 13. Juli 2026We care deeply about your privacy and respect customer choice. For teams using zero data retention, no trace and code data is ever retained. All API key use of Grok Build also respects ZDR.
If ZDR is disabled, the /privacy command is available in the CLI to disable data

Using Grok agents in background mode
Andrew Milich@milichab· 12. Juli 2026@arthurkatcher 1) Yes! Use `.grok/agents` or config.toml (see below), adding to the docs site right now.
2) Yes: Agents can spawn background subagents, or try /dashboard, to move your agent to the background and create another. I've been using /dashboard as my default.

I take it all back. We just got access to eval Grok 4.5 and it has landed above GPT-5.6-Sol and just shy of Opus for browser use.
Because cache input is expensive, the overall cost is only 10% cheaper than opus. Its overall a bit faster.
We have another opus-class model in the
Alexander Yue@Alezander907· 12. Juli 2026Some new model release and my eval scores:
gpt-5.6-sol is a small improvement on browser tasks, but seems to consume many more tokens

Claude sonnet 5 is 5th best performance at higher

Necessarily so, as power harnessed would be more than a trillion times what human civilization uses today.
The economy will be measured in energy and mass at that point, not dollars.
