Frequently Asked Questions
- How much VRAM does Vaultgemma 1B need?
Vaultgemma 1B requires 2.3 GB of VRAM at BF16.
VRAM = Weights + KV Cache + Overhead
Weights = 1.0B × 16 bits ÷ 8 = 2.1 GB
KV Cache + Overhead ≈ 0.2 GB (at 2K context + ~0.3 GB framework)
VRAM usage by quantization
BF162.3 GB- Can I run Vaultgemma 1B on a Mac?
Vaultgemma 1B requires at least 2.3 GB at BF16, which exceeds the unified memory of most consumer Macs. You would need a Mac Studio or Mac Pro with a high-memory configuration.
- Can I run Vaultgemma 1B locally?
Yes — Vaultgemma 1B can run locally on consumer hardware. At BF16 quantization it needs 2.3 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.
- How fast is Vaultgemma 1B?
At BF16, Vaultgemma 1B can reach ~1921 tok/s on AMD Instinct MI350X. On NVIDIA GeForce RTX 4090: ~286 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 ÷ 2.3 × 0.65 = ~2271 tok/s
Estimated speed at BF16 (2.3 GB)
~2271 tok/s~286 tok/s~2271 tok/s~1921 tok/sReal-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
- What's the download size of Vaultgemma 1B?
At BF16, the download is about 2.08 GB.
- Which GPUs can run Vaultgemma 1B?
50 consumer GPUs can run Vaultgemma 1B at BF16 (2.3 GB). Top options include AMD Radeon RX 6700 XT, AMD Radeon RX 6800, AMD Radeon RX 6800 XT. 50 GPUs have plenty of headroom for comfortable inference.
- Which devices can run Vaultgemma 1B?
59 devices with unified memory can run Vaultgemma 1B at BF16 (2.3 GB), including AMD Ryzen AI 9 HX 370 (Strix Point) Laptop, ASUS Ascent GX10, Apple iPhone 17 Pro, Asus ROG Flow Z13 (2025, Ryzen AI Max+ 395, 128 GB). Apple Silicon Macs use unified memory shared between CPU and GPU, making them well-suited for local LLM inference.
