If you want to try out out the GGUFs from https://huggingface.co/prism-ml/Ternary-Bonsai-2-27B-gguf#th... be aware that you need Prism's llama.cpp fork to get them to work, from https://github.com/PrismML-Eng/llama.cpp/releases/tag/prism-...

This should work:

  cd /tmp

  # Get the Prism macOS runtime
  curl -fL https://github.com/PrismML-Eng/llama.cpp/releases/download/prism-b10685-7dffb15/llama-prism-b10685-7dffb15-bin-macos-arm64.tar.gz -o bonsai-runtime.tar.gz
  tar -xzf bonsai-runtime.tar.gz

  # Get the ~5.95 GB GGUF model:
  curl -fL https://huggingface.co/prism-ml/Ternary-Bonsai-2-27B-gguf/resolve/main/Ternary-Bonsai-2-27B-PTQ1_0.gguf -o Ternary-Bonsai-2-27B-PTQ1_0.gguf

  # Run the server, I used port 8331
  ./llama-prism-b10685-7dffb15/llama-server \
    -m Ternary-Bonsai-2-27B-PTQ1_0.gguf \
    --port 8331 -ngl 99 -fa on -c 32768

Then open http://localhost:8331 for the (very good) baked in llama-server web UI... or run a prompt via the API like this:

  uvx llm openai endpoint http://127.0.0.1:8331/v1 \
    --model bonsai-2-27b --responses hi

That's running at ~20 token/second for me on an M5 Pro (after a server restart I got 44 token/second, not sure why), but I'm pretty sure something isn't working right, on startup the server said "ggml_metal_device_init: - the tensor API is not supported in this environment - disabling".

If you want to download the gguf to your regular huggingface cache directory instead of to /tmp, you can download the model and run the server in one step:

  export HF_TOKEN=xxx # optional, speeds up the download
  
  ./llama-prism-b10685-7dffb15/llama serve \
    -hf prism-ml/Ternary-Bonsai-2-27B-gguf:PTQ1_0 \
    --port 8331 -ngl 99 -fa on -c 32768

I used that to Generate an SVG of a pelican riding a bicycle:

It took 18 minutes 20 seconds. Pretty decent for a 5.5GB model file.

Honestly looks pretty good except whatever is going on with its booty. Is that an ass helmet? I cannot parse what's going on there.

Where did you get these instructions?

They have a demo repo with a setup.sh script:

https://github.com/PrismML-Eng/Bonsai-demo

The release tag and weight file you suggest doesn’t match what they wrote.

I figured them out, starting from the GGUF on Hugging Face.

If you have found better instructions and they work then use those instead!

Personally I prefer to download models directly rather than running some `./setup.sh` script where I need to then review what it does first.

		Yeah just wanted to mention in case it explains the 2x lower throughout you are seeing on M5. To be fair their documentation is a bit inconsistent in some spots. Would be good to know if the release and weights from their demo repo work better. I’m trying on a 4090 and will report back.

It would be great to have upstream llama.cpp support for this!

		Agreed. They always sound exciting to try out but are such a pain to get working.
