Working LLaMA 7B on a 64GB M2 MacBook Professional with llama.cpp

Fb’s LLaMA is a “assortment of basis language fashions starting from 7B to 65B parameters”, launched on February twenty fourth 2023.

It claims to be sufficiently small to run on client {hardware}. I simply ran the 7B mannequin on my 64GB M2 MacBook Professional!

I am utilizing llama.cpp by Georgi Gerganov, a “port of Fb’s LLaMA mannequin in C/C++”. Georgi beforehand launched whisper.cpp which does the identical factor for OpenAI’s Whisper automated speech recognition mannequin.


To run llama.cpp you want an Apple Silicon MacBook M1/M2 with xcode put in. You additionally want Python 3 – I used Python 3.10, after discovering that 3.11 did not work as a result of there was no torch wheel for it but.

You additionally want the LLaMA fashions. You possibly can request entry from Fb by means of this form, or you possibly can seize it through BitTorrent from the hyperlink in this cheeky pull request.

The mannequin is a 240GB obtain, which incorporates the 7B, 13B, 30B and 65B fashions. I’ve solely tried operating the smaller 7B mannequin up to now.

Subsequent, checkout the llama.cpp repository:

git clone
cd llama.cpp

Run make to compile the C++ code:


Subsequent you want a Python 3.10 surroundings you possibly can set up some packages into, with a purpose to run the Python script that converts the mannequin to the smaller format utilized by llama.cpp.

I take advantage of pipenv so I created an surroundings like this:

pipenv shell --python 3.10

It’s worthwhile to create a fashions/ folder in your llama.cpp listing that instantly incorporates the 7B and sibling recordsdata and folders from the LLaMA mannequin obtain. Your folder construction ought to appear to be this:

% ls ./fashions

Subsequent, set up the dependencies wanted by the Python conversion script.

pip set up torch numpy sentencepiece

Earlier than operating the conversions scripts, fashions/7B/consolidated.00.pth ought to be a 13GB file.

The primary script converts the mannequin to “ggml FP16 format”:

python fashions/7B/ 1

This could produce fashions/7B/ggml-model-f16.bin – one other 13GB file.

The second script “quantizes the mannequin to 4-bits”:

./quantize ./fashions/7B/ggml-model-f16.bin ./fashions/7B/ggml-model-q4_0.bin 2

This produces fashions/7B/ggml-model-q4_0.bin – a 3.9GB file. That is the file we’ll use to run the mannequin.

Working the mannequin

Having created the ggml-model-q4_0.bin file, we will now run the mannequin.

This is tips on how to run it and move a immediate:

./important -m ./fashions/7B/ggml-model-q4_0.bin 
  -t 8 
  -n 128 
  -p 'The primary man on the moon was '

./important --help reveals the choices. -m is the mannequin. -t is the variety of threads to make use of. -n is the variety of tokens to generate. -p is the immediate.

This is the complete assist output:

utilization: ./important [options]

  -h, --help            present this assist message and exit
  -s SEED, --seed SEED  RNG seed (default: -1)
  -t N, --threads N     variety of threads to make use of throughout computation (default: 4)
  -p PROMPT, --prompt PROMPT
                        immediate to begin era with (default: random)
  -n N, --n_predict N   variety of tokens to foretell (default: 128)
  --top_k N             top-k sampling (default: 40)
  --top_p N             top-p sampling (default: 0.9)
  --temp N              temperature (default: 0.8)
  -b N, --batch_size N  batch dimension for immediate processing (default: 8)
  -m FNAME, --model FNAME
                        mannequin path (default: fashions/llama-7B/ggml-model.bin)

Outcomes of some prompts

The primary man on the moon was

My first immediate was The primary man on the moon was – I bought again this:

Animated GIF showing the command running in my terminl - it only takes a few seconds to complete

-p 'The primary man on the moon was '

The primary man on the moon was 38-year-old astronaut Neil A. Armstrong.
Apollo 11 landed on the moon on July 20, 1969.
Apollo 11 was the primary manned mission to land on the Moon. It was the end result of the House Race, throughout which america house program turned the primary to land people on the Moon, in July 1969, with Neil Armstrong and Edwin "Buzz" Aldrin.
Apollo 11 launched from the Kennedy House Middle on July 16, 1

To my shock, this passes an preliminary reality verify – that was the precise age, center preliminary and date for Armstrong’s moon touchdown.

For this smaller mannequin my instinct is that it is going to be susceptible to all types of errors, so I am impressed how properly this held up.

Within the guide the writer reveals that he had referred to as a demon named Demise, which appeared to him within the type of a goat with wings. He took the demon's identify and put it in his guide.

Bit bizarre. I could not confirm if a guide of this identify exists or not.

This immediate managed to generate some useful Python code!

def get_file_info(filename, fullpath):
    Get file data (i.e., permission, proprietor, group, dimension)

I had beforehand tried prompts like “Python code to open a file: def” however these weren’t efficient – it looks as if it bought confused at mixing common English and code.

Nicely these are all garbage! Clearly getting respectable pun concepts requires a a lot bigger mannequin dimension.

It hasn’t been instruction tuned

One of many key causes GPT-3 and ChatGPT are so helpful is that they’ve been by means of instruction tuning, as described by OpenAI in Aligning language models to follow instructions.

This extra coaching gave them the flexibility to reply successfully to human directions – issues like “Summarize this” or “Write a poem about an otter” or “Extract the details from this text”.

So far as I can inform LLaMA has not had this, which makes it so much tougher to make use of. Prompts should be within the basic type of “Some textual content which can be accomplished by …” – so immediate engineering for these fashions goes to be so much tougher, at the least for now.

I’ve not found out the precise immediate to get it to summarize textual content but, for instance.

Usually although, this has completely blown me away. I believed it will be years earlier than we may run fashions like this on private {hardware}, however right here we’re already!

Useful resource utilization

Whereas operating, the mannequin makes use of about 4GB of RAM and Exercise Monitor reveals it utilizing 748% CPU – which is sensible since I advised it to make use of 8 CPU cores.

I think about it is potential to run a bigger mannequin equivalent to 13B on this {hardware}, however I’ve not found out how to do this but. Fb declare the next:

LLaMA-13B outperforms GPT-3 (175B) on most benchmarks, and LLaMA-65B is aggressive with the very best fashions, Chinchilla70B and PaLM-540B

So operating even simply the 13B mannequin could possibly be an enormous step up.
