Acknowledgements
RenameWise stands on a lot of other people's work. This page names it, and carries the notices those licences ask us to pass on to you.

The AI model
Qwen3-VL-4B-Instruct — the vision-language model that actually reads your files. Created by the Qwen team at Alibaba Cloud and released under the Apache License 2.0. We use it unmodified.
This is the piece that makes RenameWise possible. A model small enough to run on a laptop, good enough to read a crumpled receipt, and openly licensed enough to build a business on — all three at once is not a given, and we're grateful for it.
The authors ask that work built on the model cites their technical reports, and we're happy to:
- Qwen3 Technical Report, Qwen Team, 2025
- Qwen2.5-VL Technical Report, Qwen Team, 2025
The inference engine
llama.cpp — runs the model on Apple Silicon via Metal. By Georgi Gerganov and contributors, under the MIT License, along with the ggml tensor library.
Without llama.cpp there is no practical way to ship a vision model that runs on a MacBook without a cloud bill attached. The full licence text is included inside the app.
