Eric Siu switched back to OpenAI's Codex after finding it outperforms Claude, though he still pays for Claude Teams. He breaks down the competitive landscape between OpenAI, Anthropic, Google, and xAI, and what's shifting in model performance and market share.
OpenAI has actually gone down. Anthropic is emerging, and then you have Google at the bottom, xAI at the bottom, in the race for artificial intelligence supremacy. Who knows how true this is right now? Because Neil, one thing I'll say to you is that I have actually switched back to OpenAI. Months ago, I was talking about Claude. Everyone was talking about Claude. Everyone was talking about Opus. Even the guy I had the AI conversation with this morning were like, oh, we switched over to Codex. And I hope my team isn't listening to this. It'll be a pain in the ass to switch them. So I'll tell you what. CTO, OpenAI. I'm on OpenAI, okay? Even though I pay for Claude Teams. But Codex is— it is the shit right now. Pardon my language, but everyone that's serious right now is back on 5.5, ChatGPT 5.5. And I'm just saying this tug of war is happening all the time. So we might say Anthropic's ahead right now and they have the mindshare, but I wouldn't be surprised if OpenAI just takes it right back. And I wouldn't be surprised if Google comes out of nowhere and just kicks both of their butts.
