LLM GPU VRAM & Hardware Sizer
Estimate exact GPU VRAM needed to run or fine-tune models like Llama 3, DeepSeek, and Mistral.
GPU Memory Estimation Equation:
\( \text{VRAM}_{\text{GB}} = \left( \frac{\text{Params (B)} \times \text{Bytes/Param}}{10^9} \right) \times 1.20_{\text{KV Overhead}} + \text{Activation Buffer} \)
