I use Chat-GPT and Microsoft Copilot primarily and have never used Grok. The CEO of OpenAI stated that GPT-5 was intended to boost performance in software/code generation, but overall I would say that it has provided more in-depth and accurate information compared to its predecessors. Also, I don't know if you saw, but ChatGPT actually beat Grok in an AI chess tournament.
For AI fans (like me)

Yeah but it was Chat GPT o3 model which best Grok 4 in chess. Grok is developing really fast.
What do you think is better GPT 5 or Grok . I have noticed that earlier Grok was able to render PDFs but now It isn't able to render it and GPT 5 is better at creative writing and image generation. So winner should be GPT 5. Guys vote which is better not which is your favourite because even my favourite is Grok but I know GPT 5 is better. Anyone who has tried Grok 4 can drop their opinions down and vote
