"Finally playing w/ the ChatGPT Apps SDK. It looks like you basically just set up an MCP server and effectively define your endpoints. I'm not sure if this would drive new user growth. I think the Q is if ChatGPT itself selects certain tools to answer a user query but I suspect most users if they cite a specific tool are already an acquired user by that tool"

"Old news but totally missed that GPT5 introduced X new params on their /completions endpoint. You can now tune reasoning (how deep to think) and verbosity (how succinct the answer). This can enable a better experience but also creates new UX challenges (eg designing async if long-waits are involved etc)"

"Have to call-out the X feed algo + the revival of links + minor UI updates (making it closer to the Threads UI) have vastly improved the X experience. It feels like a completely different app"
