<!-- Provide a quick summary of what the model is/does. --> |
|
|
|
dragon-llama-7b-v0 part of the dRAGon ("Delivering RAG On ...") model series, RAG-instruct trained on top of a LLama-2 base model. |
|
|
|
DRAGON models are fine-tuned with high-quality custom instruct datasets, designed for production quality use in RAG scenarios. |
|
|
|
|

## Uses |
|
|
|
<!-- Address questions around how the model is intended to be used, including the foreseeable users of the model and those affected by the model. --> |
|
|
|
The intended use of DRAGON models is two-fold: |
|
|
|
1. Provide high-quality RAG-Instruct models designed for fact-based, no "hallucination" question-answering in connection with an enterprise RAG workflow. |
|
|
|
2. DRAGON models are fine-tuned on top of leading base foundation models, generally in the 6-7B+ range, and purposefully rolled-out across multiple base models to provide choices and "drop-in" replacements for RAG specific use cases. |
|
|
|
3. DRAGON models were trained on the same principles as the BLING models, so generally, it should be easy to "upgrade" from a BLING model in testing to a DRAGON model in production. |
|
|
|
|
|
### Direct Use |
|
|
|
<!-- This section is for the model use without fine-tuning or plugging into a larger ecosystem/app. --> |
|
|
|
DRAGON is designed for enterprise automation use cases, especially in knowledge-intensive industries, such as financial services, |
|
legal and regulatory industries with complex information sources. |
|
|
|
DRAGON models have been trained for common RAG scenarios, specifically: question-answering, key-value extraction, and basic summarization as the core instruction types |
|
without the need for a lot of complex instruction verbiage - provide a text passage context, ask questions, and get clear fact-based responses. |
|
|
|
|
|
## Bias, Risks, and Limitations |
|
|
|
<!-- This section is meant to convey both technical and sociotechnical limitations. --> |
|
|
|
Any model can provide inaccurate or incomplete information, and should be used in conjunction with appropriate safeguards and fact-checking mechanisms. |
|
|
|
|
|
## How to Get Started with the Model |
|
|
|
The fastest way to get started with dRAGon is through direct import in transformers: |
|
|
|
from transformers import AutoTokenizer, AutoModelForCausalLM |
|
tokenizer = AutoTokenizer.from_pretrained("dragon-llama-7b-v0") |
|
model = AutoModelForCausalLM.from_pretrained("dragon-llama-7b-v0") |
|
|
|
Please refer to the generation_test .py files in the Files repository, which includes 200 samples and script to test the model. The **generation_test_llmware_script.py** includes built-in llmware capabilities for fact-checking, as well as easy integration with document parsing and actual retrieval to swap out the test set for RAG workflow consisting of business documents. |
|
|
|
The dRAGon model was fine-tuned with a simple "\<human> and \<bot>" wrapper, so to get the best results, wrap inference entries as: |
|
|
|
full_prompt = "<human>: " + my_prompt + "\n" + "<bot>:" |
|
|
|
The BLING model was fine-tuned with closed-context samples, which assume generally that the prompt consists of two sub-parts: |
|
|
|
1. Text Passage Context, and |
|
2. Specific question or instruction based on the text passage |
|
|
|
To get the best results, package "my_prompt" as follows: |
|
|
|
my_prompt = {{text_passage}} + "\n" + {{question/instruction}} |
|
|
|
|
|
If you are using a HuggingFace generation script: |
|
|
|
# prepare prompt packaging used in fine-tuning process |
|
new_prompt = "<human>: " + entries["context"] + "\n" + entries["query"] + "\n" + "<bot>:" |
|
|
|
inputs = tokenizer(new_prompt, return_tensors="pt") |
|
start_of_output = len(inputs.input_ids[0]) |
|
|
|
# temperature: set at 0.3 for consistency of output |
|
# max_new_tokens: set at 100 - may prematurely stop a few of the summaries |
|
|
|
outputs = model.generate( |
|
inputs.input_ids.to(device), |
|
eos_token_id=tokenizer.eos_token_id, |
|
pad_token_id=tokenizer.eos_token_id, |
|
do_sample=True, |
|
temperature=0.3, |
|
max_new_tokens=100, |
|
) |
|
|
|
output_only = tokenizer.decode(outputs[0][start_of_output:],skip_special_tokens=True) |
|
|
|
# note: due to artifact of the fine-tuning, use this post-processing with HF generation |
|
|
|
eot = output_only.find("<|endoftext|>") |
|
if eot > -1: |
|
output_only = output_only[:eot] |
