Details & FAQ

Workflow, boundaries, sources, and common questions in one compact block.

Overview

For users who want to know whether 3B, 8B, 14B, 32B, or 70B models are practical locally before downloading or buying hardware.

Hardware fit

Checks VRAM, RAM, and CPU for GPU, GPU+RAM split, or CPU-only.

Status + score

Shows whether the setup is good, tight, slow, or not sensible.

Q4 to FP16

Compares quantization, context length, and model size directly.

Download & RAM

Estimates model size, KV cache, overhead, and recommended RAM.

Safety, legal notes, and sources

The tool does not auto-scan devices or send hardware data. It only calculates from your inputs.

Models, quantizations, and runtimes have different memory layouts. The calculator is intentionally conservative.
Very long context windows increase KV cache strongly and can break an otherwise fitting setup.

Estimate without guarantee. Final performance depends on model architecture, runtime, drivers, batch size, and background load.
