Eric Siu explains why he's switched to ChatGPT as his main tool. He compares it to Claude and other AI models, noting that product improvements shift preferences fast and no AI company has built a lasting advantage yet.

Until very recently, everything was about Claude. It's like they could do no wrong, right? Here's the thing. In the past couple of weeks or so, because I tend to live in this world, OpenAI is slowly taking the crown back, right? Everyone now on X is talking about Codex. They're talking about ChatGPT 5.5. They're talking about the /goal commanders, all these things. And so I think it's pretty funny that in AI we're very promiscuous. There's a tug of war. All that matters in this world when you're talking about trying to stay at the cutting edge of intelligence is the product itself. Right? It's like nothing matters more. Like 1 or 2 weeks, 3 weeks ago, I would just be talking about Claude all day, okay? And now I'm like, oh man, this OpenAI has made a comeback. I will gladly switch over to it. So it's like there isn't really like a defined moat quite yet.
