GPU Memory / Model Fit

Check which model sizes fit in GPU memory. VRAM requirements depend on precision (FP16, INT8, INT4) and batch size.

Model parameters in billions (e.g. 7, 70, 405)
Lower precision = less memory, slight quality trade-off
Available VRAM; KV cache adds ~20% for inference
Inference needs extra memory for context; add ~20%
Higher batch = more throughput, more memory
