What AI models can the Other iPhone (8 GB RAM) run?

RAM: 8.0 GB
One app can use: 4.4 GB
Memory bandwidth: 60 GB/s
FP16 compute: 2.0 TFLOPS
Released: 2025

176 / 622 LLMs run Best: Nemotron Labs Dory 1.0 4B 7 / 61 Image models run Best: SDXL Turbo 0 / 43 Video models run None fit 0 / 70 Decision models run No iOS app

A model runs in RAM (the 8.0 GB here), not in storage. Storage only keeps the downloaded files, and even the smallest size has room for several. iOS lets one app hold only part of the RAM before it closes the app, so we plan around 4.4 GB; a model bigger than that won’t run. Phone apps such as PocketPal AI download a model once, then run it with no connection.
