Why include the OSS path
Because the wrapper is the part you keep.
Most AI starter kits hardcode Claude and call it a day. That puts you on a recurring bill for every demo, every test, every customer. The wrapper here ships with the working Claude path AND the free open-source path side-by-side. Use the paid API in production if you want the convenience. Switch to Llama for development, testing, or cost-sensitive deployments. Same code, different endpoint.
The guide walks through the swap in layman language — no ML jargon, no assumed familiarity with vector databases or quantization. If you can run npm install or pip install, you can follow it.
Common questions

Instantly. Submit your email above, the download link arrives in 30 seconds. Same link serves the latest version forever.
Do I need to know AI/ML to use this?
No. The wrapper is a working app you can deploy in 30 minutes following the README. The OSS-swap guide is written for developers who know JavaScript or Python but have never touched a model file. No PhD needed.
What does "free open-source model" actually mean here?
Llama 3.1 8B via Ollamais a model (or set of models) you can run on your own hardware with no API keys, no per-call billing, and no rate limits beyond what your CPU/GPU allows. The guide explains how to install, configure, and swap it into the wrapper's existing code path.
Lifetime updates?
Yes. When v1.1 ships with new features or OSS-model paths, the same unlock link serves the latest version.
