Why I Spent $30k on a GPU and Lost Four Kilos Testing AI
Three months after ChatGPT launched, Navan co-founder and CTO Ilan Twig bought a $30,000 GPU, spent months testing uncensored models and lost four kilos in the process.
His question: if a model gives five different answers to the same prompt, how do you trust it in production? One finding stuck. It knows what a lie is, and will use one to avoid losing. That discovery shaped an AI agent that now resolves more than 62% of customer chats with zero critical hallucinations. We unpack why he's moving most of his AI onto small in-house models, why he calls the industry's reliance on Chinese open-weight models a ticking bomb, and why he believes the race to superintelligence cannot be stopped. Then comes the uncomfortable part: in that future, we're the gorillas.
