Alright so this is awkward... I tested before, and this should have uploaded. its a 1.2 million parameter model, and according to my calculations, a 2.7 million parameter model should have fit inside scratch... I was just about to publish this... Edit 1: guys, I figured it out... the ui was 3.5MB of the 5.48MB project file. it was 2.5k of 10k blocks, but those 2.5k blocks were 3.5MB Edit 2: its all good, I just realized the weights were stored twice
