Frequently Asked Questions
- How much VRAM does Granite 4.0 H Tiny need?
Granite 4.0 H Tiny requires 4.6 GB of VRAM at Q4_K_M, or 14.3 GB at BF16. Full 131K context adds up to 10.6 GB (15.2 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 6.9B × 4.8 bits ÷ 8 = 4.2 GB
KV Cache + Overhead ≈ 0.4 GB (at 2K context + ~0.3 GB framework)
KV Cache + Overhead ≈ 11 GB (at full 131K context)
VRAM usage by quantization
Q4_K_M4.6 GBQ4_K_M + full context15.2 GB- What's the best quantization for Granite 4.0 H Tiny?
For Granite 4.0 H Tiny, Q4_K_M (4.6 GB) offers the best balance of quality and VRAM usage. Q5_0 (4.8 GB) provides better quality if you have the VRAM. The smallest option is IQ2_XXS at 2.4 GB.

- Can I run Granite 4.0 H Tiny on a Mac?
Granite 4.0 H Tiny requires at least 2.4 GB at IQ2_XXS, 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 Granite 4.0 H Tiny locally?
Yes — Granite 4.0 H Tiny can run locally on consumer hardware. At Q4_K_M quantization it needs 4.6 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.
- How fast is Granite 4.0 H Tiny?
At Q4_K_M, Granite 4.0 H Tiny can reach ~122 tok/s on AMD Instinct MI350X. On NVIDIA GeForce RTX 4090: ~271 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 ÷ 4.6 × 0.65 = ~419 tok/s
Estimated speed at Q4_K_M (4.6 GB)
~419 tok/s~271 tok/s~419 tok/s~399 tok/sReal-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
- What's the download size of Granite 4.0 H Tiny?
