Update(1) 2026-04-24: apparently, VirusTotal does not like the llamafiles and marks them "suspicious". There's not much I can do there, I guess. Let us wait untill the other scanners try it; until then -- feel free to e.g. ClamAV scan them after download, but also feel free to redo it yourself following the links provided: your result will be binary compatible with what is uploaded here.
Update(2) 2026-04-24: hmm, the "suspicious" flag seems to be cleared on some binaries. Good. May be just give it time to update the databases.
Update(3) 2026-04-24: testing virustotal reaction on other files, see Qwen3.5-4B-llamafile/README.md

A llamafile is a universal (APE) single-file executable, which is based on llama.cpp-built binaries. It contains an embedded LLM model and can provide a console and/or a web interface to chat with it.

"and/or" here has a literal meaning -- one can either run a console chat (--chat), or a web server (--server), or -- by default -- both.
NB(1): by default the web server attempts to listen on all available interfaces -- run it as --host 127.0.0.1 to make it private to your system only!
NB(2): there's also a cli completion interface (--cli), if you wish -- check the docs!

How to use:

Default arguments:

--temp 0.6 --top-p 0.95 --top-k 20 # instead of -1

Quirks:

For some quirks and workarounds (like how to make this run on WSL), see the second link above; in particular, if you are seeing a message like this:

Cannot open assembly '...': File does not contain a valid CIL image.

The reason might be that you have wine installed and it tries to run the executable (and fails). There are workarounds available -- see above; if that does not work, please open an issue, and when I see it (which might not happen immediately), we will think of something.
