Gemma 4 26B Mac demo clarifies SSD streaming, not 2GB RAM usage

A recent demonstration of Google's Gemma 4 26B-A4B model on Macs has sparked discussion about its memory requirements. While initially presented as a 2 GB model, closer examination reveals it utilizes SSD streaming for its Mixture-of-Experts architecture, requiring approximately 3 GB of resident RAM and significantly more disk space. This technique allows for lower active memory usage by loading model components on demand from the SSD, rather than keeping the entire model in RAM. The actual memory footprint can vary considerably depending on the specific runtime and configuration, with some setups demanding up to 26 GB of RAM. AI
