• How does the compression work? The model is compressed with GGUF.
• How does the model quality change? The quality of the model output might vary compared to the base model.
• What is the model format? We use GGUF format.
• What calibration data has been used? If needed by the compression method, we used WikiText as the calibration data.

Downloading and running the models

How to download GGUF files ?

• LM Studio
• LoLLMS Web UI
• Faraday.dev

• Option A - Downloading in text-generation-webui:
  • Step 1: Under Download Model, you can enter the model repo: PrunaAI/zephyr-orpo-141b-A35b-v0.1-GGUF-smashed-smashed and below it, a specific filename to download, such as: phi-2.IQ3_M.gguf.
  • Step 2: Then click Download.
• Option B - Downloading on the command line (including multiple files at once):
  • Step 1: We recommend using the huggingface-hub Python library:
  pip3 install huggingface-hub
  • Step 2: Then you can download any individual model file to the current directory, at high speed, with a command like this:
  huggingface-cli download PrunaAI/zephyr-orpo-141b-A35b-v0.1-GGUF-smashed-smashed zephyr-orpo-141b-A35b-v0.1.IQ3_M.gguf --local-dir . --local-dir-use-symlinks False
  More advanced huggingface-cli download usage (click to read)

  Alternatively, you can also download multiple files at once with a pattern:

  huggingface-cli download PrunaAI/zephyr-orpo-141b-A35b-v0.1-GGUF-smashed-smashed --local-dir . --local-dir-use-symlinks False --include='*Q4_K*gguf'

  For more documentation on downloading with huggingface-cli, please see: HF -> Hub Python Library -> Download files -> Download from the CLI.

  To accelerate downloads on fast connections (1Gbit/s or higher), install hf_transfer:

  pip3 install hf_transfer

  And set environment variable HF_HUB_ENABLE_HF_TRANSFER to 1:

  HF_HUB_ENABLE_HF_TRANSFER=1 huggingface-cli download PrunaAI/zephyr-orpo-141b-A35b-v0.1-GGUF-smashed-smashed zephyr-orpo-141b-A35b-v0.1.IQ3_M.gguf --local-dir . --local-dir-use-symlinks False

  Windows Command Line users: You can set the environment variable by running set HF_HUB_ENABLE_HF_TRANSFER=1 before the download command.

How to run model in GGUF format?

• Option A - Introductory example with llama.cpp command
  Make sure you are using llama.cpp from commit d0cee0d or later.
  ./main -ngl 35 -m zephyr-orpo-141b-A35b-v0.1.IQ3_M.gguf --color -c 32768 --temp 0.7 --repeat_penalty 1.1 -n -1 -p "<s>[INST] {prompt\} [/INST]"
  Change -ngl 32 to the number of layers to offload to GPU. Remove it if you don't have GPU acceleration.
  Change -c 32768 to the desired sequence length. For extended sequence models - eg 8K, 16K, 32K - the necessary RoPE scaling parameters are read from the GGUF file and set by llama.cpp automatically. Note that longer sequence lengths require much more resources, so you may need to reduce this value.
  If you want to have a chat-style conversation, replace the -p <PROMPT> argument with -i -ins
  For other parameters and how to use them, please refer to the llama.cpp documentation
• Option B - Running in text-generation-webui
  Further instructions can be found in the text-generation-webui documentation, here: text-generation-webui/docs/04 ‐ Model Tab.md.
• Option C - Running from Python code
  You can use GGUF models from Python using the llama-cpp-python or ctransformers libraries. Note that at the time of writing (Nov 27th 2023), ctransformers has not been updated for some time and is not compatible with some recent models. Therefore I recommend you use llama-cpp-python.

  How to load this model in Python code, using llama-cpp-python

  For full documentation, please see: llama-cpp-python docs.

  First install the package

  Run one of the following commands, according to your system:
  shell

  1# Base ctransformers with no GPU acceleration 2pip install llama-cpp-python 3# With NVidia CUDA acceleration 4CMAKE_ARGS="-DLLAMA_CUBLAS=on" pip install llama-cpp-python 5# Or with OpenBLAS acceleration 6CMAKE_ARGS="-DLLAMA_BLAS=ON -DLLAMA_BLAS_VENDOR=OpenBLAS" pip install llama-cpp-python 7# Or with CLBLast acceleration 8CMAKE_ARGS="-DLLAMA_CLBLAST=on" pip install llama-cpp-python 9# Or with AMD ROCm GPU acceleration (Linux only) 10CMAKE_ARGS="-DLLAMA_HIPBLAS=on" pip install llama-cpp-python 11# Or with Metal GPU acceleration for macOS systems only 12CMAKE_ARGS="-DLLAMA_METAL=on" pip install llama-cpp-python 13 14# In windows, to set the variables CMAKE_ARGS in PowerShell, follow this format; eg for NVidia CUDA: 15$env:CMAKE_ARGS = "-DLLAMA_OPENBLAS=on" 16pip install llama-cpp-python

  Simple llama-cpp-python example code

  python

  1from llama_cpp import Llama 2 3# Set gpu_layers to the number of layers to offload to GPU. Set to 0 if no GPU acceleration is available on your system. 4llm = Llama( 5 model_path="./zephyr-orpo-141b-A35b-v0.1.IQ3_M.gguf", # Download the model file first 6 n_ctx=32768, # The max sequence length to use - note that longer sequence lengths require much more resources 7 n_threads=8, # The number of CPU threads to use, tailor to your system and the resulting performance 8 n_gpu_layers=35 # The number of layers to offload to GPU, if you have GPU acceleration available 9) 10 11# Simple inference example 12output = llm( 13 "<s>[INST] {prompt} [/INST]", # Prompt 14 max_tokens=512, # Generate up to 512 tokens 15 stop=["</s>"], # Example stop token - not necessarily correct for this specific model! Please check before using. 16 echo=True # Whether to echo the prompt 17) 18 19# Chat Completion API 20 21llm = Llama(model_path="./zephyr-orpo-141b-A35b-v0.1.IQ3_M.gguf", chat_format="llama-2") # Set chat_format according to the model you are using 22llm.create_chat_completion( 23 messages = [ 24 {"role": "system", "content": "You are a story writing assistant."}, 25 { 26 "role": "user", 27 "content": "Write a story about llamas." 28 } 29 ] 30)
• Option D - Running with LangChain
  Here are guides on using llama-cpp-python and ctransformers with LangChain:
  • LangChain + llama-cpp-python
  • LangChain + ctransformers
