Compatibility verdict VRAM threshold engine

No, not enough memory would not load

No. Sarvam-30B needs ~21.7 GB even at Q4_K_M, but iPhone 16 Pro only has ~4.5 GB usable.

Needs ~21.7 GB Device usable ~4.5 GB

Needs ~21.7 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 17.2 GB: Sarvam-30B needs roughly 21.7 GB at Q4_K_M and iPhone 16 Pro leaves only about 4.5 GB usable for a model. The lightest tracked hardware that runs Sarvam-30B is the Nvidia GeForce RTX 4090 (24GB) at 24 GB. See Sarvam-30B on Nvidia GeForce RTX 4090 (24GB).

FAQ

Can iPhone 16 Pro run Sarvam-30B?

No. Sarvam-30B needs ~21.7 GB even at Q4_K_M, but iPhone 16 Pro only has ~4.5 GB usable.

How much memory does Sarvam-30B need?

iPhone 16 Pro does not have enough memory. At Q4_K_M the weights are ~19.6 GB; with KV cache and runtime overhead, budget ~21.7 GB at a 4k context. It is a Mixture-of-Experts model (30B total / 2.4B active), so all experts must stay in memory; memory tracks total params, not active params.

What is the best tool to run Sarvam-30B on iOS?

On iPhone and iPad, Apple Foundation Models (Built into iOS 26, ~3B on-device model, zero download, fully private.) is the standard choice. Phones realistically run 1B-4B class models. Anything larger thermally throttles or OOMs.

Weights are measured from GGUF files; KV cache and overhead are computed, so totals can vary ~15% with context and runtime. Any tok/s is a bandwidth estimate. See methodology.
