Inference of [Facebook's LLaMA](https://github.com/facebookresearch/llama) model in pure C/C++
**Hot topics**
- Running on Windows: https://github.com/ggerganov/llama.cpp/issues/22
- Fix Tokenizer / Unicode support: https://github.com/ggerganov/llama.cpp/issues/11
## Description
The main goal is to run the model using 4-bit quantization on a MacBook

This was [hacked in an evening](https://github.com/ggerganov/llama.cpp/issues/33#issuecomment-1465108022) - I have no idea if it works correctly.
Please do not make conclusions about the models based on the results from this implementation.
For all I know, it can be completely wrong. This project is for educational purposes and is not going to be maintained properly.
New features will probably be added mostly through community contributions, if any.

Supported platforms:
- [X] Mac OS
- [X] Linux
- [ ] Windows (soon)
- [X] Windows (via CMake)

## Limitations
- Not sure if my tokenizer is correct. There are a few places where we might have a mistake:
- https://github.com/ggerganov/llama.cpp/blob/26c084662903ddaca19bef982831bfb0856e8257/convert-pth-to-ggml.py#L79-L87

In general, it seems to work, but I think it fails for unicode character support. Hopefully, someone can help with that
- I don't know yet how much the quantization affects the quality of the generated text
- Probably the token sampling can be improved
- The Accelerate framework is actually currently unused since I found that for tensor shapes typical for the Decoder,

### Contributing
- There are 2 git branches: [master](https://github.com/ggerganov/llama.cpp/commits/master) and [dev](https://github.com/ggerganov/llama.cpp/commits/dev)
- Contributors can open PRs to either one
- Collaborators can push straight into `dev`, but need to open a PR to get stuff to `master`
- Contributors can open PRs
- Collaborators can push to branches in the `llama.cpp` repo
- Collaborators will be invited based on contributions
- `dev` branch is considered unstable
- `master` branch is considered stable and approved. 3-rd party projects should use the `master` branch
General principles to follow when writing code:
### Coding guide-lines
- Avoid adding third-party dependencies, extra files, extra headers, etc.
- Always consider cross-compatibility with other operating systems and architectures
- Avoid fancy looking modern STL constructs, use basic for loops, avoid templates, keep it simple
- There are no strict rules for the code style, but try to follow the patterns in the code (indentation, spaces, etc.). Vertical alignment makes things more readable and easier to batch edit
- Clean-up any tailing whitespaces, use 4 spaces indentation, brackets on same line, `int * var`
- Look at the [good first issues](https://github.com/ggerganov/llama.cpp/issues?q=is%3Aissue+is%3Aopen+label%3A%22good+first+issue%22) for tasks
