The most advanced lib for dealing with LLMs is
https://github.com/zmedelis/bosquet
There is also https://github.com/cjbarre/multi-gpt/tree/main but it hasn't been update in 3 months and seems rather basic.
Alternatively, you can shoot me an email at
(->> '(102 117 110 116 97 105 110 64 109 101 46 99 111 109) (map char) (apply str))
and I'll prepare a repo for what I've been working on. It's usable but I wanted to clear some things up before a public release.
