SmolLM2 360M GPU Hardware & VRAM Calculator
Hugging Face's ultra-lightweight language model designed for on-device browser and mobile edge deployment.
📊 Real-Time VRAM Mathematical Formulation & Derivation
How did we arrive at 6 GB? Below is the verified industrial infrastructure forecasting model.
The VRAM Forecasting Equation
Total VRAM = (Model Weights + KV Cache) × System Overhead
VRAM = ((Params × Bits / 8) + (Context / 1024 × 0.5)) × 1.25
1. Input Parameters & Constants Mapping
Model Variables
- • Params (Model Size): 0.36 Billion
- • Bits (Precision): 4-bit (Selected via slider)
Runtime Constants
- • Context Window: 8,192 Tokens (Selected via slider)
- • KV Cache Factor: 0.5 GB / 1K Tokens (Empirical baseline)
- • System Overhead: 1.25 (25%) (CUDA Context & Activation buffer)
2. Step-by-Step Calculation Engine
[Step 1] Compute Model Weights Allocation:
Formula: (Parameters × Bits) / 8 Bytes per GB
➔ (0.36B × 4) / 8 = 0.18 GB
[Step 2] Compute Key-Value (KV) Cache Matrix Size:
Formula: (Tokens / 1024) × 0.5 GB Baseline
➔ (8192 / 1024) × 0.5 = 4.00 GB
[Step 3] Apply System Overhead Risk Buffer:
Formula: (Weights + KV Cache) × 1.25 CUDA Runtime Multiplier
➔ (0.18GB + 4.00GB) × 1.25 = 5.22 GB
[Final Step] Rounding Ceiling (Ceil):⌈ 5.22 ⌉ = 6 GB
