Model Card

rStar2-Agent-14B-Q4_0-GGUF

This model was converted to GGUF format from `rstar2-reproduce/rStar2-Agent-14B` using llama.cpp via the ggml.ai's GGUF-my-repo space. Refer to the original model card for more details on the model.

Use with Llamafile :)

Portable and fast...

bash

wget "https://github.com/Mozilla-Ocho/llamafile/releases/download/0.9.3/llamafile-0.9.3"
chmod +x llamafile-0.9.3
wget "https://huggingface.co/F-urkan/rStar2-Agent-14B-Q4_0-GGUF/resolve/main/rstar2-agent-14b-q4_0.gguf"
./llamafile-0.9.3 --server --port 8081 --no-mmap --nobrowser -ngl 9999 -m rstar2-agent-14b-q4_0.gguf

Requirements:

—8 gb vram
—8 gb disk space

Use with llama.cpp

Install llama.cpp through brew (works on Mac and Linux)

bash

brew install llama.cpp

Invoke the llama.cpp server or the CLI.

CLI:

bash

llama-cli --hf-repo F-urkan/rStar2-Agent-14B-Q4_0-GGUF --hf-file rstar2-agent-14b-q4_0.gguf -p "The meaning to life and the universe is"

Server:

bash

llama-server --hf-repo F-urkan/rStar2-Agent-14B-Q4_0-GGUF --hf-file rstar2-agent-14b-q4_0.gguf -c 2048

Note: You can also use this checkpoint directly through the usage steps listed in the Llama.cpp repo as well.

Step 1: Clone llama.cpp from GitHub.

git clone https://github.com/ggerganov/llama.cpp

Step 2: Move into the llama.cpp folder and build it with LLAMA_CURL=1 flag along with other hardware-specific flags (for ex: LLAMA_CUDA=1 for Nvidia GPUs on Linux).

cd llama.cpp && LLAMA_CURL=1 make

Step 3: Run inference through the main binary.

./llama-cli --hf-repo F-urkan/rStar2-Agent-14B-Q4_0-GGUF --hf-file rstar2-agent-14b-q4_0.gguf -p "The meaning to life and the universe is"

./llama-server --hf-repo F-urkan/rStar2-Agent-14B-Q4_0-GGUF --hf-file rstar2-agent-14b-q4_0.gguf -c 2048
