Tesla engineering redesigned lithium refining from physics first principles
Tesla North America@tesla_na· 18 avr. 2026Our Lithium Refinery is designed to have a much lower carbon footprint than traditional hard rock refineries
– Acid-free refining helps produce a safe coproduct
– Water is recycled throughout production, with every drop treated & cleaned on site
– Designed to close the loop for

比如说在Tesla使用Grok，它总是答非所问，还总是在那里尬笑；比如用Grok生成图片，总是乱码；等等。

Grok 4.3 (beta) has been released by @xai 🔥🔥
The new version of Grok is currently available to the highest tier plan SuperGrok Heavy.
With 1T params Grok 4.3 is twice as big as Grok 4.20, and was also trained much longer. It should provide a decent jump in performance.
Elon Musk
@elonmusk · 18 avr. 2026
This is still 0.5T, but a more recent training checkpoint.
1T model is ~5 days away from finishing initial training. Will be a major step change improvement in coding, long context and skills.
The SpaceXAI model factory is finally working. Should be an improved base model landing every ~2 weeks.

Grok 4.3 is still an early beta that will improve almost every day, but try it out!
We will publish release notes as we fix bugs and add functionality.
X Freeze@XFreeze· 17 avr. 2026Grok 4.3 beta is natively multimodal, and the front-end capabilities are insane
You can literally just upload a screenshot of any website you like, and Grok will instantly write the code to clone it for you with an cool UI
You don't even need to write a complex prompt...just

Correct
Penny2x@imPenny2x· 17 avr. 202699% of people really do not understand abundance as Elon describes it.
The fundamental reason is that they don’t understand compound growth.
Same people who would probably pick 1 million dollars today over a penny that doubles in value every day for 30 days.
It’s a bad choice

In a normal economy, issuing more money simply increases the dollar price of the existing output of goods & services, meaning people do NOT get more stuff.

If everyone gets a million dollars.
No one has a million dollars.
I'm not sure why no one understands this.
Elon Musk@elonmusk· 17 avr. 2026Universal HIGH INCOME via checks issued by the Federal government is the best way to deal with unemployment caused by AI.
AI/robotics will produce goods & services far in excess of the increase in the money supply, so there will not be inflation.

In a normal economy, issuing more money simply increases the dollar price of the existing output of goods & services, meaning people do NOT get more stuff.
If AI/robots massively increase goods & services output, then you actually MUST issue dollars to people or there will be massive disinflation. Prices are simply the ratio of goods & services output to number of dollars.

tetsuo@tetsuoai· 17 avr. 2026grok 4.3 beta can use an ubuntu shell and a persistent file layer to generate artifacts
grok wrote python to encode the xai / grok logo into audio, i gave it the script back and had it render a spectrogram video from that signal, and use the grok_files tool to save the mp4 into

Brian Roemmele@BrianRoemmele· 17 avr. 2026The new beta of Grok 4.3 is stunning.
In my view it is more of a leap between Grok 3 to 4. The leap of 4.2 to 4.3 is dramatic.
