Notable Quotes
“I've used 6.8 billion tokens on Codeex... I am using this tool every day and building stuff and just constantly constantly creating. I absolutely love building inside of codex and I love using these new models.”
— Host
“You don't need to go and subscribe to monthly SaaS products or go and hire developers to build the stuff for you. You just go to something like Codeex with the GPT 5.6 model and say, 'Here's something I'm trying to solve in my business. Can you build the solution for me?'”
— Host
“Nate never stood in front of a camera for this. He didn't record this narration and he never opened the editor. He gave me one prompt. That's it.”
