Hi Fazier! I built Gemma4All Hardware Checker after watching people (myself included) download 20+ GB of model weights, only to find out their machine couldn't actually run them. The checker gives you a verdict in about 10 seconds — pick your device and memory, and see which of the 5 Gemma 4 sizes fit, with the best quantization for each. It's free, no signup. I'd love your feedback on what hardware or open models you'd want covered next!
