MERAK-7B-V2 GGML

readme adapted from TheBloke

These files are GGML format model files for MERAK-7B-V2.

GGML files are for CPU + GPU inference using llama.cpp and libraries and UIs which support this format, such as:

• KoboldCpp, a powerful GGML web UI with full GPU acceleration out of the box. Especially good for story telling.
• LoLLMS Web UI, a great web UI with GPU acceleration via the c_transformers backend.
• LM Studio, a fully featured local GUI. Supports full GPU accel on macOS. Also supports Windows, without GPU accel.
• text-generation-webui, the most popular web UI. Requires extra steps to enable GPU accel via llama.cpp backend.
• ctransformers, a Python library with LangChain support and OpenAI-compatible AI server.
• llama-cpp-python, a Python library with OpenAI-compatible API server.

Compatibility

Original llama.cpp quant methods: q4_0, q4_1, q5_0, q5_1, q8_0

These are guaranteed to be compatible with any UIs, tools and libraries released since late May. They may be phased out soon, as they are largely superseded by the new k-quant methods.

New k-quant methods: q2_K, q3_K_S, q3_K_M, q3_K_L, q4_K_S, q4_K_M, q5_K_S, q6_K

These new quantisation methods are compatible with llama.cpp as of June 6th, commit 2d43387.

They are now also compatible with recent releases of text-generation-webui, KoboldCpp, llama-cpp-python, ctransformers, rustformers and most others. For compatibility with other tools and libraries, please check their documentation.

Explanation of the new k-quant methods

<details> <summary>Click to see details</summary>

The new methods available are:

• GGML_TYPE_Q2_K - "type-1" 2-bit quantization in super-blocks containing 16 blocks, each block having 16 weight. Block scales and mins are quantized with 4 bits. This ends up effectively using 2.5625 bits per weight (bpw)
• GGML_TYPE_Q3_K - "type-0" 3-bit quantization in super-blocks containing 16 blocks, each block having 16 weights. Scales are quantized with 6 bits. This end up using 3.4375 bpw.
• GGML_TYPE_Q4_K - "type-1" 4-bit quantization in super-blocks containing 8 blocks, each block having 32 weights. Scales and mins are quantized with 6 bits. This ends up using 4.5 bpw.
• GGML_TYPE_Q5_K - "type-1" 5-bit quantization. Same super-block structure as GGML_TYPE_Q4_K resulting in 5.5 bpw
• GGML_TYPE_Q6_K - "type-0" 6-bit quantization. Super-blocks with 16 blocks, each block having 16 weights. Scales are quantized with 8 bits. This ends up using 6.5625 bpw
• GGML_TYPE_Q8_K - "type-0" 8-bit quantization. Only used for quantizing intermediate results. The difference to the existing Q8_0 is that the block size is 256. All 2-6 bit dot products are implemented for this quantization type.

Original model card: 6TH PROTOTYPE OF MERAK-7B-V2!

Merak-7B is the Large Language Model of Indonesia Languange

This model is based on Meta Llama-2-7B-Chat-HF and fine tuned by some of Indonesia Wikipedia articles that I cleaned before.

Leveraging QLoRA (QLora: Efficient Finetuning of Quantized LLMs), Merak-7B is able to run with 16 GB VRAM

Licensed under Creative Commons-By Attribution-Share Alike-Non Commercial (CC-BY-SA-NC 4.0) Merak-7B empowers AI enthusiasts, researchers alike.

Big thanks to all my friends and communities that help to build our first model. Feel free, to ask me about the model and please share the news on your social media.

HOW TO USE

Installation

Please make sure you have installed CUDA driver in your system, Python 3.10 and PyTorch 2. Then install this library in terminal

pip install bitsandbytes==0.39.1
pip install transformers==4.31.0
pip install peft==0.4.0
pip install accelerate==0.20.3
pip install einops==0.6.1 scipy sentencepiece datasets

Using BitsandBytes and it run with >= 10 GB VRAM GPU

from transformers import AutoTokenizer, AutoConfig, AutoModelForCausalLM, BitsAndBytesConfig, LlamaTokenizer
from peft import PeftModel, PeftConfig

model_id = "Ichsan2895/Merak-7B-v2"

def generate_response(question: str) -> str:
  prompt = f"<|prompt|>{question}\n<|answer|>".strip()

  encoding = tokenizer(prompt, return_tensors='pt').to("cuda")
  with torch.inference_mode():
    outputs = model.generate(input_ids=encoding.input_ids,
                             attention_mask=encoding.attention_mask,
                             eos_token_id=tokenizer.pad_token_id,

    response = tokenizer.decode(outputs[0], skip_special_tokes=True)

    assistant_start = "<|answer|>"
    response_start = response.find(assistant_start)
return response[response_start + len(assistant_start) :].strip()

prompt = "Siapa penulis naskah proklamasi kemerdekaan Indonesia?"
print(generate_response(prompt))

From my experience, For better answer, please don’t use BitsandBytes 4-bit Quantization, but it using higher VRAM

                                             trust_remote_code=True)

    response = tokenizer.decode(outputs[0], skip_special_tokes=True)

    assistant_start = "<|answer|>"
    response_start = response.find(assistant_start)
return response[response_start + len(assistant_start) :].strip()
