I built Zeta AI v5 because Google changed Gemini API key format to AQ... in May 2026 and broke thousands of apps. Zeta AI fixes it. Works with new AQ... keys + old AIza... keys. Features: Chat like ChatGPT, Upload photo & ask, Generate images, Video AI, UPSC/Exam answers, No login needed, Works in 200+ countries even with slow internet. I fixed gemini-2.0-flash deprecated error -> now uses gemini-2.5-flash. 100% working, deployed on Cloudflare free tier. Made in Unnao, UP for the world. Try it!
