Frequently Asked Questions

How much VRAM does Gallium 350M need?

Gallium 350M requires 0.6 GB of VRAM at Q4_K_M, or 1.1 GB at BF16. Full 128K context adds up to 1.8 GB (2.4 GB total).

VRAM = Weights + KV Cache + Overhead

Weights = 353M × 4.8 bits ÷ 8 = 0.2 GB

KV Cache + Overhead ≈ 0.4 GB (at 2K context + ~0.3 GB framework)

Fit ratings and hardware model lists check this model with room for a 16K-token context, which needs a little more memory.

KV Cache + Overhead ≈ 2.2 GB (at full 128K context)

Can I run Gallium 350M on a Mac?

Yes — MacBook Air 13" M3 (8 GB) and 145 other Macs can run Gallium 350M. Apple Silicon uses unified memory, so the model shares RAM with the system. At Q4_K_M you need at least 0.6 GB of usable unified memory (RAM minus macOS overhead).

Can I run Gallium 350M locally?

Yes — Gallium 350M can run locally on consumer hardware. Popular tools include Ollama, LM Studio, and llama.cpp.

How fast is Gallium 350M?

At Q4_K_M, Gallium 350M can reach ~8276 tok/s on AMD Instinct MI350X. On NVIDIA GeForce RTX 4090: ~1130 tok/s. Speed depends mainly on GPU memory bandwidth. Real-world results typically within ±20%.

tok/s = (bandwidth GB/s ÷ model GB) × efficiency

Example: NVIDIA B200 → 8000 ÷ 0.58 × 0.65 = ~8966 tok/s
