 A text editor that lets you view the text through the eyes of an LLM, see what it expects and what it finds surprising, generate continuations,
 and seamlessly explore different alternatives at every point - as in [the device](https://en.wikipedia.org/wiki/Autopen), and a [pen](https://en.wikipedia.org/wiki/Pen_%28enclosure%29) for [assorted](https://en.wikipedia.org/wiki/LLaMA) [macrofauna](https://lmsys.org/blog/2023-03-30-vicuna/).

 On Windows: try the VS2022 .sln file (and vcpkg). imgui should be cloned as on Linux, and llama.cpp should be cloned and built with a configuration matching the Release/Debug setting you pick (as libcommon has to be statically linked). Some adjustment of include and library directories will probably be necessary.
 
 ### To run
+Under Linux:
 ```
 ./cmake-build-Release/output/autopen
 ```
-The model location is hardcoded to `./qwen2.5-1.5b-instruct-q4_k_m.gguf` (so in particular, this file is assumed to be present), but feel free to change this.
 
+Under Windows: run `autopen.exe` in a folder containing the .otf/.ttc fonts and all required DLLs.
