I tested the same prompt on both Grok 4.3 and GPT 5.5: “Count to 10 starting from 11” ChatGPT 5.5 gave the obvious 11–20 Grok 4.3 gave 11, 10 and explained why going backwards was the only logical move Grok’s logical reasoning is at a level most models still can’t even touch
Here we go... Grok 4.3 just dropped. Now it can create other file formats like Slides, Sheets, PDFs, Docs, etc.
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
@minchoi is showing a real operator signal: This is literally my new workflow now: Real-time research/search → Grok 4.3 Planning… The useful angle is what changes in the workflow: faster proof, better distribution, or a cleaner reason for builders to act
