End of an era, but the start of something even bigger. Today, Gemini CLI will stop serving requests for Google AI Pro, Google AI Ultra, and free tier individual accounts as we transition over to the Antigravity CLI! It started with weekly Gemini CLI updates and grew to be bigger than I ever thought it would. I’m deeply grateful for the community, the code, and the absolute ride of the past year. Thank you all so much!! Next stop: Antigravity SDK. Stoked to keep building with you all there and will be sharing more in the coming weeks! 🚀🚀🚀
