Inference of [LLaMA](https://arxiv.org/abs/2302.13971) model in pure C/C++ Inference of [LLaMA](https://arxiv.org/abs/2302.13971) model in pure C/C++
### 🚧 Incoming breaking change + refactoring: ### Hot topics
See PR https://github.com/ggerganov/llama.cpp/pull/2398 for more info. A new file format has been introduced: [GGUF](https://github.com/ggerganov/llama.cpp/pull/2398)
To devs: avoid making big changes to `llama.h` / `llama.cpp` until merged Last revision compatible with the old format: [dadbed9](https://github.com/ggerganov/llama.cpp/commit/dadbed99e65252d79f81101a392d0d6497b86caa)

Returns list of utf-8 byte and a corresponding list of unicode strings.
The reversible bpe codes work on unicode strings.
This means you need a large # of unicode characters in your vocab if you want to avoid UNKs.
When you're at something like a 10B token dataset you end up needing around 5K for decent coverage.
This is a significant percentage of your normal, say, 32K bpe vocab.
To avoid that, we want lookup tables between utf-8 bytes and unicode strings.

## Verifying that the model is running on the GPU with cuBLAS ## Verifying that the model is running on the GPU with cuBLAS
Make sure you compiled llama with the correct env variables according to [this guide](../README.md#cublas), so that llama accepts the `-ngl N` (or `--n-gpu-layers N`) flag. When running llama, you may configure `N` to be very large, and llama will offload the maximum possible number of layers to the GPU, even if it's less than the number you configured.
