yes, I've now I tried both the 20 GB version (gemma4:31b) which is the largest on the page[1], and the ~10 GB version (gemma4:e4b). The 20 GB version was rather slow even when fully loaded and with some RAM still left free, and the 10 GB version was speedy. I installed openclaw but couldn't get it to act as an agent the way Claude Code does. If you'd like to see a video of how both of them perform with almost nothing else running, on a Mac Mini M4 with 24 GB of RAM, you can see one here (I just recorded it):[2]

Thank you for the video. It was super helpful. the 20g version was clearly struggling but the 10g version was flying by. I think it was probably virtualized memory pages that were actually on disk causing the issue. Perhaps that and the memory compression.
