Can I run Falcon-H1-34B-Instruct on iPhone 17?

Compatibility verdict VRAM threshold engine

No, not enough memory would not load

No. Falcon-H1-34B-Instruct needs ~21.1 GB even at Q4_K_M, but iPhone 17 only has ~4.5 GB usable.

Needs ~21.1 GB Device usable ~4.5 GB

Needs ~21.1 GB even at Q4_K_M, but only ~4.5 GB is usable.

That figure is at a 4k context and moves about ±15% as context length changes.

The gap is about 16.6 GB: Falcon-H1-34B-Instruct needs roughly 21.1 GB at Q4_K_M and iPhone 17 leaves only about 4.5 GB usable for a model. The lightest tracked hardware that runs Falcon-H1-34B-Instruct is the Nvidia GeForce RTX 4090 (24GB) at 24 GB. See Falcon-H1-34B-Instruct on Nvidia GeForce RTX 4090 (24GB).
