Billing unit: Hardware and model licence separate
Platform: Local cross-platform executable

Overview

What you provide

A trusted prebuilt llamafile or a runtime plus compatible model weights, followed by a prompt.

What you get

Local model responses; the project also provides a separate whisperfile transcription tool.

Choosing this tool

Choose Llamafile for a portable demonstration or a model handoff where a single executable is useful. Ollama is better aligned with managing several models through a service and API; llama.cpp exposes lower-level runtime and hardware choices. Match the model size to the target machine before distributing it.

A decision worked through

For a Windows handoff above 4 GB, do not send a large bundled executable and assume it will run. The official guide requires a separate runtime with external GGUF weights for that case. A small demonstration model proves packaging works, not that a larger model will fit or answer well.

Llamafile: alternatives and trade-offs

Compare Llamafile on the documented workflow and cost boundary below; this is an official-source comparison, not a hands-on benchmark.

Product	Price / unit	Free allowance	Input → output	Key limit
LlamafileRead profile Official source ↗	Open source; local hardware	Runtime source available	Model + prompt → local response	Windows bundle must be below 4 GB
OllamaRead profile Official source ↗	MIT local runtime	Local software	Models + prompts → API responses	Cloud service billed separately

Setup & workflow

Download a prebuilt model from the official project links.
Apply the platform-specific executable instructions.
Run locally and test a representative prompt before sharing the package.

Requirements & installation

Enough memory and storage for the chosen model; executable permission on Unix-like systems or an .exe suffix on Windows.

Limits & review

Windows executable size is limited to under 4 GB. Newer 0.10 builds differ from the classic 0.9 experience; model compatibility and memory needs vary.

Your part

Verify the model source and licence and assess output on the actual target hardware.
