grok 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 the product's files layer i opened the file from the files panel and played it myself this is getting crazy

Grok 4.3 can create PDF and almost any file formats like Sheets, Slides, Doc

The 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.

i gave Grok 4.3 beta an absolutely psychotic eval and it passed conflicting records, stale CRM data, signed docs with higher precedence, prompt injection buried in the exhibits, timezone conversions, holiday-aware SLA math, annual-prepay revenue normalization, ARR, weighted gross margin, exact JSON output, and a launch recommendation that had to be correct under policy constraints Grok got all of it right that is an insane level of composure for a beta model

Neuralink is just so incredible 🥹 Neuralink will help millions restore speech, blindness, and so much more! These videos make me emotional every single time.

The South African laws are literally super racist, plain and simple. It’s not complicated: imagine if the law was called “White Empowerment”, instead of “Black Empowerment”! People would have a seizure 😂 South Africa now has more anti-White laws than Apartheid had anti-Black laws. Think about that for a second … The current South African government has objectively implemented Apartheid 2.0. Shame on them.
