<!-- Provide a quick summary of what the model is/does. -->

bling-tiny-llama-v0 is part of the BLING ("Best Little Instruct No-GPU-required...") model series, RAG-instruct trained on top of a TinyLlama-1.1b base model.

BLING models are fine-tuned with high-quality custom instruct datasets, designed for rapid testing and prototyping in RAG scenarios.

Benchmark Tests

Evaluated against the benchmark test: RAG-Instruct-Benchmark-Tester Average of 2 Test Runs with 1 point for correct answer, 0.5 point for partial correct or blank / NF, 0.0 points for incorrect, and -1 points for hallucinations.

--Accuracy Score: 86.5 correct out of 100 --Not Found Classification: 85.0% --Boolean: 82.50% --Math/Logic: 37.50% --Complex Questions (1-5): 3 --Summarization Quality (1-5): 3 (Coherent, extractive) --Hallucinations: No hallucinations observed in test runs.

Direct Use

<!-- This section is for the model use without fine-tuning or plugging into a larger ecosystem/app. -->

BLING is designed for enterprise automation use cases, especially in knowledge-intensive industries, such as financial services, legal and regulatory industries with complex information sources.

BLING 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 BLING is through direct import in transformers:

from transformers import AutoTokenizer, AutoModelForCausalLM tokenizer = AutoTokenizer.frompretrained("bling-tiny-llama-v0") model = AutoModelForCausalLM.frompretrained("bling-tiny-llama-v0")

Please refer to the generationtest .py files in the Files repository, which includes 200 samples and script to test the model. The **generationtestllmwarescript.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 BLING model was fine-tuned with a simple "\<human> and \<bot> wrapper", so to get the best results, wrap inference entries as:

fullprompt = "<human>: " + myprompt + "\n" + "<bot>:"

The BLING model was fine-tuned with closed-context samples, which assume generally that the prompt consists of two sub-parts:

1. 1.Text Passage Context, and
2. 2.Specific question or instruction based on the text passage

To get the best results, package "my_prompt" as follows:

myprompt = {{textpassage}} + "\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(newprompt, returntensors="pt") startofoutput = len(inputs.input_ids[0])

# temperature: set at 0.3 for consistency of output # maxnewtokens: set at 100 - may prematurely stop a few of the summaries

outputs = model.generate( inputs.inputids.to(device), eostokenid=tokenizer.eostokenid, padtokenid=tokenizer.eostokenid, dosample=True, temperature=0.3, maxnewtokens=100, )

outputonly = tokenizer.decode(outputs[0][startofoutput:],skipspecial_tokens=True)
