I assume that "pretty fast" depends on the phone. My old Pixel 4a ran Gemma-3n-E2B-it-int4 without problems. Still, it took over 10 minutes to finish answering "What can you see?" when given an image from my recent photos. Final stats: 15.9 seconds to first token 16.4 tokens/second prefill speed 0.33 tokens/second decode speed 662 seconds to complete the answer
I did the same thing on my Pixel Fold. Tried two different images with two different prompts: "What can you see?" and "Describe this image" First image ('Describe', photo of my desk) - 15.6 seconds to first token - 2.6 tokens/second - Total 180 seconds Second image ('What can you see?', photo of a bowl of pasta) - 10.3 seconds to first token - 3.1 tokens/second - Total 26 seconds The Edge Gallery app defaults to CPU…
Pixel Fold was in the Pixel 8 generation but uses the Tensor G2 from the 7s. Pixel 7 release date = October 2022
That's a 26 month difference, yet a full order of magnitude difference in token generation rate on the CPU. Who said Moore's Law is dead? ;)
