Falcon-40B-Instruct GPTQ

This repo contains an experimantal GPTQ 4bit model for Falcon-40B-Instruct.

It is the result of quantising to 4bit using AutoGPTQ.

EXPERIMENTAL

Please note this is an experimental first model. Support for it is currently quite limited.

To use it you will require:

  1. AutoGPTQ, from the latest main branch and compiled with pip install .
  2. pip install einops

You can then use it immediately from Python code - see example code below

text-generation-webui

There is also provisional AutoGPTQ support in text-generation-webui.

However at the time I'm writing this, a commit is needed to text-generation-webui to enable it to load this model.

I have opened a PR here; once this is merged, text-generation-webui will support this GPTQ model.

To get it working before the PR is merged, you will need to:

  1. Edit text-generation-webui/modules/AutoGPTQ_loader.py
  2. Make the following change:

Find the line that says:

'use_safetensors': use_safetensors,

And after it, add:

'trust_remote_code': shared.args.trust_remote_code,

Once you are done the file should look like this

  1. Then save and close the file, and launch text-generation-webui as described below

How to download and use this model in text-generation-webui

  1. Launch text-generation-webui with the following command-line arguments: --autogptq --trust_remote_code
  2. Click the Model tab.
  3. Under Download custom model or LoRA, enter TheBloke/falcon-7B-instruct-GPTQ.
  4. Click Download.
  5. Wait until it says it's finished downloading.
  6. Click the Refresh icon next to Model in the top left.
  7. In the Model drop-down: choose the model you just downloaded, falcon-7B-instruct-GPTQ.
  8. Once it says it's loaded, click the Text Generation tab and enter a prompt!

About trust_remote_code

Please be aware that this command line argument causes Python code provided by Falcon to be executed on your machine.

This code is required at the moment because Falcon is too new to be supported by Hugging Face transformers. At some point in the future transformers will support the model natively, and then trust_remote_code will no longer be needed.

In this repo you can see two .py files - these are the files that get executed. They are copied from the base repo at Falcon-7B-Instruct.

Simple Python example code

To run this code you need to install AutoGPTQ from source:

git clone https://github.com/PanQiWei/AutoGPTQ
cd AutoGPTQ
pip install . # This step requires CUDA toolkit installed

And install einops:

pip install einops

You can then run this example code:

import torch
from transformers import AutoTokenizer
from auto_gptq import AutoGPTQForCausalLM

# Download the model from HF and store it locally, then reference its location here:
quantized_model_dir = "/path/to/falcon7b-instruct-gptq"

from transformers import AutoTokenizer
tokenizer = AutoTokenizer.from_pretrained(quantized_model_dir, use_fast=False)

model = AutoGPTQForCausalLM.from_quantized(quantized_model_dir, device="cuda:0", use_triton=False, use_safetensors=True, torch_dtype=torch.float32, trust_remote_code=True)

prompt = "Write a story about llamas"
prompt_template = f"### Instruction: {prompt}\n### Response:"

tokens = tokenizer(prompt_template, return_tensors="pt").to("cuda:0").input_ids
output = model.generate(input_ids=tokens, max_new_tokens=100, do_sample=True, temperature=0.8)
print(tokenizer.decode(output[0]))

Provided files

gptq_model-4bit.safetensors

This will work with AutoGPTQ as of commit 3cb1bf5 (3cb1bf5a6d43a06dc34c6442287965d1838303d3)

It was created with no groupsize to reduce VRAM requirements as much as possible, with desc_act (act-order) to increase inference quality.

  • gptq_model-4bit.safetensors
    • Works only with latest AutoGPTQ CUDA, compiled from source as of commit 3cb1bf5
      • At this time it does not work with AutoGPTQ Triton, but support will hopefully be added in time.
    • Works with text-generation-webui using --autogptq --trust_remote_code
      • At this time it does NOT work with one-click-installers
    • Does not work with any version of GPTQ-for-LLaMa
    • Parameters: Groupsize = 64. No act-order.

Want to support my work?

I've had a lot of people ask if they can contribute. I love providing models and helping people, but it is starting to rack up pretty big cloud computing bills.

So if you're able and willing to contribute, it'd be most gratefully received and will help me to keep providing models, and work on various AI proejcts.

✨ Original model card: Falcon-40B-Instruct

✨ Falcon-40B-Instruct

Falcon-40B-Instruct is a 40B parameters causal decoder-only model built by TII based on Falcon-40B and finetuned on a mixture of Baize. It is made available under the TII Falcon LLM License.

Paper coming soon 😊.

Why use Falcon-40B-Instruct?

💬 This is an instruct model, which may not be ideal for further finetuning. If you are interested in building your own instruct/chat model, we recommend starting from Falcon-40B.

💸 Looking for a smaller, less expensive model? Falcon-7B-Instruct is Falcon-40B-Instruct's small brother!

from transformers import AutoTokenizer, AutoModelForCausalLM
import transformers
import torch

model = "tiiuae/falcon-40b-instruct"

pipeline = transformers.pipeline(
    "text-generation",
    model=model,
    tokenizer=tokenizer,
    torch_dtype=torch.bfloat16,
    trust_remote_code=True,
    device_map="auto",
)
sequences = pipeline(
   "Girafatron is obsessed with giraffes, the most glorious animal on the face of this Earth. Giraftron believes all other animals are irrelevant when compared to the glorious majesty of the giraffe.\nDaniel: Hello, Girafatron!\nGirafatron:",

Uses

Direct Use

Falcon-40B-Instruct has been finetuned on a chat dataset.

Out-of-Scope Use

Production use without adequate assessment of risks and mitigation; any use cases which may be considered irresponsible or harmful.

Bias, Risks, and Limitations

Falcon-40B-Instruct is mostly trained on English data, and will not generalize appropriately to other languages. Furthermore, as it is trained on a large-scale corpora representative of the web, it will carry the stereotypes and biases commonly encountered online.

Recommendations

We recommend users of Falcon-40B-Instruct to develop guardrails and to take appropriate precautions for any production use.

Model Architecture and Objective

Falcon-40B is a causal decoder-only model trained on a causal language modeling task (i.e., predict the next token).

The architecture is broadly adapted from the GPT-3 paper (Brown et al., 2020), with the following differences:

For multiquery, we are using an internal variant which uses independent key and values per tensor parallel degree.

Hyperparameter Value Comment
Layers 60
d_model 8192
head_dim 64 Reduced to optimise for FlashAttention
Vocabulary 65024
Sequence length 2048

Compute Infrastructure

Hardware

Falcon-40B-Instruct was trained on AWS SageMaker, on 64 A100 40GB GPUs in P4d instances.

Software

Falcon-40B-Instruct was trained a custom distributed training codebase, Gigatron. It uses a 3D parallelism approach combined with ZeRO and high-performance Triton kernels (FlashAttention, etc.)
