Abstract Heresies: llambda.lisp

llambda.lisp

I wanted to run LLM models locally on my machine. I discovered<br>that llama.cpp is how people run models locally, and that the<br>popular LLM servers like Ollama and lmstudio and unsloth use<br>llama.cpp under the hood.

llama.cpp is, of course, written in C++. I don't care for C++ and<br>I prefer Common Lisp. With the appropriate declarations, Common<br>Lisp code should be in the same performance ballpark as C++ code.<br>So I decided to write a Common Lisp implementation of llama.cpp,<br>which I call llambda.lisp.

It is available<br>on GitHub.com/jrm-code-project/llambda<br>If you care to contribute, it could use routing for architectures<br>other than gemma, GPU support, NPU support, and other features.

I need to assume windows (since there is a kernel32 dependency), don't I?

To use it out of the box, yes, I wrote it under windows and it uses MapViewOfFile rather than mmap. But it doesn't have a deep dependency here and porting it to linux should be simple.
