The Google Pixel 9A features the Tensor G4 chip but has a limited version of Gemini AI due to its 8GB RAM. It runs the smaller Gemini Nano 1.0 XXS model, which only activates when needed, unlike the always-on AI in pricier Pixel 9 models. As a result, the Pixel 9A lacks features like AI-powered Pixel Screenshots and Call Notes but still supports Recorder app summaries. Google previously restricted Gemini AI to the Pixel 8 Pro but later added it to the Pixel 8 after user feedback.
