Sign-In With GPT, Anthropic Vs. the Pope, Paramount Rebrands as Skydance | Diet TBPN

The hosts of TBPN open their Q4 episode with a deceptively small piece of news from OpenAI's Dev Day: "Sign in with ChatGPT." It sounds like a boring developer feature, but they argue it could reshape the economic structure of the AI industry. From there, the conversation spirals into a Vatican standoff over machine consciousness, a surprising stat about AI adoption, Tesla's delivery numbers, the Paramount-Skydance merger, and Ben Affleck's surprisingly technical take on training video models. The throughline is the messy, awkward adolescence of AI as it tries to find a business model, a moral status, and a place in everyday life.

The "Bring Your Own Compute" Economy

The hosts zero in on Sign in with ChatGPT as potentially the most consequential announcement of the week, precisely because it is boring. They frame it as a solution to a problem that has plagued indie developers since the generative AI boom began: you build a magical product, it scales, and suddenly you are stuck with a $30,000 API bill. The new feature lets users "bring their own compute" (BYOC) by authorizing an app to run OpenAI model requests against their personal ChatGPT subscription. A developer named Peter Yang captured the sentiment: "I have a live language learning app that I wasn't planning to launch to users due to API costs, but letting users sign in with ChatGPT makes this viable."
