How to Run Llamafile Locally on Windows/Mac/Linux
Using llamafile effectively requires understanding its functionalities and how to implement them. Here's a detailed guide with sample codes to help you get started:
1. Downloading and Installing Llamafile
Begin by downloading the llamafile executable. On Unix-like systems, you can use curl to download and chmod to make it executable:
curl -L https://github.com/Mozilla-Ocho/llamafile/releases/download/0.1/llamafile-server-0.1 > llamafile
chmod +x llamafile
For Windows, the process might require renaming the file to llamafile.exe and ensuring it's executable.
2. Running Llamafile
To run llamafile, use the command line. Here's how to display the help message:
./llamafile --helpFor loading a model, use the -m flag followed by the path to the model weights:
./llamafile -m ~/weights/foo.gguf3. Example: Running a Command-Line Binary
Suppose you have the mistral-7b-instruct-v0.1-Q4_K_M-main.llamafile. To run this command-line binary, execute the following:
./mistral-7b-instruct-v0.1-Q4_K_M-main.llamafile4. Launching a Server Binary
If you're using a server binary like wizardcoder-python-13b-server.llamafile, you can start a local web server. Run the following command:
./wizardcoder-python-13b-server.llamafileThis will launch a server at 127.0.0.1:8080, providing a web-based chatbot interface.
5. Custom Building from Source
For custom building, first download the cosmocc toolchain:
mkdir -p cosmocc
cd cosmocc
curl -L https://github.com/jart/cosmopolitan/releases/download/3.1.1/cosmocc-3.1.1.zip > cosmocc.zip
unzip cosmocc.zip
cd ..
export PATH="$PWD/cosmocc/bin:$PATH"
Then, compile the llamafile repository:
make -j86. Embedding Weights into the Executable
To embed weights into the executable, use the zipalign tool provided by llamafile. Here's an example command:
o//llamafile/zipalign -j0 \
o//llama.cpp/server/server \
~/weights/llava-v1.5-7b-Q8_0.gguf \
~/weights/llava-v1.5-7b-mmproj-Q8_0.gguf
7. Running the HTTP Server with Embedded Weights
To run the HTTP server with embedded weights, execute:
o//llama.cpp/server/server \
-m llava-v1.5-7b-Q8_0.gguf \
--mmproj llava-v1.5-7b-mmproj-Q8_0.gguf \
--host 0.0.0.0
This will launch a browser tab for interactive chat and image upload capabilities.
8. Setting Default Arguments for Simplified Execution
Create a .args file with default arguments:
cat <<EOF >.args
-m
llava-v1.5-7b-Q8_0.gguf
--mmproj
llava-v1.5-7b-mmproj-Q8_0.gguf
--host
0.0.0.0
...
EOF
Then, add the arguments file to the executable:
mv o//llama.cpp/server/server server.com
zip server.com .args
mv server.com server
./server
This allows you to run the server with ./server, using the predefined arguments for a smoother experience.
By following these steps and utilizing the sample codes, you can effectively set up and utilize llamafile for various AI development tasks, enhancing efficiency and productivity in your projects.
