Hmmm... They probably reduce the size of the model to 25GB thru quantization (it will be an MoE) z NAND-O sampling is in 2028 They probably can achieve this by late 2028 or early 2029

Quoting @firesidealpha: Qualcomm CEO reveals AI companies want phones running 100-billion-parameter models continuously by 2028--and confirms some are building phones

Cristiano Amon: “I have to be careful not to disclose names, but some AI companies—some of the companies at the forefront of AI—are telling Qualcomm, ‘By 2028, I need to make sure that I have the ability to run at least a 100-billion-parameter model in a phone, and I need to have this thing running kind of all the time.’”

Alex Heath: “So you’re saying there are AI companies that are talking about—”

Cristiano Amon: “Well, AI companies are starting to do phones.”
