Pixtral Large: Falls behind in label-based tasks but shines in rationale-based performance, indicating superior reasoning and explanation capabilities.

This evolution demonstrates Pixtral Large’s focus on tasks requiring deeper comprehension and reasoning, making it a strong contender for specialized use cases.

Benchmarking Results

Datasets Used

To test Pixtral Large, I benchmarked it against its predecessor and GPT-4V using two datasets:

ArxivQA: Research paper-based QA tasks with GPT-4V inferences for comparison.
Flickr30k: A classic image captioning dataset enhanced with GPT-4O-generated captions.

Evaluation Metrics

I used Cosine Similarity to measure semantic alignment between generated outputs and reference data. Metrics included win rate, average similarity, and top-1, top-5, top-10 scores.

ArxivQA Results

From 1,000 randomly selected images, Pixtral Large demonstrated a stronger ability to reason through scientific and mathematical content. While it struggled with label-based evaluations compared to Pixtral 12B, it outperformed in rationale-based tasks. This indicates a shift toward deeper reasoning capabilities, ideal for complex QA scenarios.

Transform UI Screenshots into HTML & CSS with Qwen Coder and Qwen VL

Aryan Kargwal — Thu, 14 Nov 2024 16:43:38 +0000

🎥Youtube Video Link: Click Me

Imagine this: you’re working on a website redesign, and you’ve just captured a UI screenshot that embodies the look you want. Wouldn’t it be incredible if you could automatically turn that image into HTML and CSS? This tutorial will show you exactly how to make that happen, transforming visual designs into code using cutting-edge vision-language models (VLMs) and Qwen Coder.

In this setup, we’ll build a pipeline where an AI model analyzes your UI design image, understands its layout, colors, typography, and structure, and then generates clean, organized HTML and CSS code. This process opens up a world of possibilities for UI prototyping, automated design-to-code workflows, and quick mockup generation.

Some cool points we'll cover:

Upload and Describe UI Designs: How we upload a UI screenshot and get a detailed breakdown of the design elements.
Generate HTML & CSS with AI: Transforming these descriptions into fully functional HTML and CSS code for quick web design prototyping.

Let’s get started!

Step 1: Setting Up API Details and Image Encoding

First, let’s configure the API endpoint, headers, and a helper function to encode images into Base64. This encoding step allows us to send the image data to the model.

import json
import requests
import base64
from PIL import Image
from io import BytesIO

# Set API details
url = "https://proxy.tune.app/chat/completions"
headers = {
    "Authorization": "YOUR_API_KEY",  # Replace with your actual API key
    "Content-Type": "application/json",
}

# Encode image in Base64 format
def encode_image(image):
    if image.mode == 'RGBA':
        image = image.convert('RGB')  # Convert RGBA to RGB
    buffered = BytesIO()
    image.save(buffered, format="JPEG")
    return base64.b64encode(buffered.getvalue()).decode('utf-8')

Step 2: Querying the Vision-Language Model for Description

In this step, we’ll create a function that queries the VLM to analyze the UI image and provide a detailed description. This model captures all aspects of the UI, including color schemes, typography, layout structures, and icons, which are essential for accurately generating HTML and CSS.

# Query the model for a description of the image
def query_model(base64_image, prompt, model_id, max_tokens=1000, temperature=0.9):
    image_content = {
        "type": "image_url",
        "image_url": {
            "url": f"data:image/jpeg;base64,{base64_image}"
        }
    }

    data = {
        "model": model_id,
        "messages": [
            {
                "role": "user",
                "content": [
                    {"type": "text", "text": prompt},
                    image_content
                ]
            }
        ],
        "max_tokens": max_tokens,
    }

    response = requests.post(url, headers=headers, json=data)
    if response.status_code == 200:
        answer = response.json().get('choices', [{}])[0].get('message', {}).get('content', "")
        return answer.strip()
    else:
        return f"Error: {response.status_code} - {response.text}"

Step 3: Extracting HTML and CSS Code from Model Response

Once we have the description, we prompt Qwen Coder to generate HTML and CSS based on the UI layout. Our code will parse the response, extracting any HTML and CSS content for easy file output.

import re

# Extract HTML and CSS from model response
def extract_html_css(response_text):
    html_match = re.search(r"### HTML\n```

html\n(.*?)

```", response_text, re.DOTALL)
    css_match = re.search(r"### CSS.*\n```

css\n(.*?)

```", response_text, re.DOTALL)

    html_code = html_match.group(1).strip() if html_match else ""
    css_code = css_match.group(1).strip() if css_match else ""

    return html_code, css_code

# Save HTML and CSS to files
def write_files(html_code, css_code):
    with open("index.html", "w") as html_file:
        html_file.write(html_code)
    with open("styles.css", "w") as css_file:
        css_file.write(css_code)

Step 4: Building the Streamlit App for User Interaction

Our final step is setting up the Streamlit interface. This UI allows users to upload images, choose a model, generate descriptions, and output HTML/CSS.

import streamlit as st

# Streamlit UI setup
st.title("Image Description and HTML/CSS Generation")
model_choice = st.selectbox("Select Model for Image Understanding", 
                            options=["qwen/qwen-2-vl-72b", "openai/gpt-4o", "mistral/pixtral-12B-2409", "meta/llama-3.2-90b-vision"],
                            index=0)
uploaded_image = st.file_uploader("Choose an image...", type=["jpg", "jpeg", "png"])

if st.button("Generate Description"):
    if uploaded_image:
        image = Image.open(uploaded_image)
        base64_image = encode_image(image)
        st.image(image)

        # Generate the UI description
        description_prompt = "Please analyze this software interface image and provide a detailed description."
        description = query_model(base64_image, description_prompt, model_id=model_choice)
        st.subheader("Generated Description:")
        st.markdown(description)

        if description:
            # Generate HTML and CSS
            html_css_data = {
                "temperature": 0.9,
                "messages": [
                    {"role": "system", "content": "You are TuneStudio, a coding assistant that generates HTML and CSS based on descriptions."},
                    {"role": "user", "content": f"Please create HTML and CSS based on the following detailed description: {description}"}
                ],
                "model": "qwen/qwen-2.5-coder-32b",
                "max_tokens": 3000
            }

            response = requests.post(url, headers=headers, json=html_css_data)
            if response.status_code == 200:
                html_css_code = response.json().get('choices', [{}])[0].get('message', {}).get('content', '')
                html_code, css_code = extract_html_css(html_css_code)

                if html_code and css_code:
                    write_files(html_code, css_code)
                    st.success("HTML and CSS files have been generated.")
                else:
                    st.error("HTML/CSS extraction failed.")

                st.subheader("Generated HTML and CSS:")
                st.code(html_css_code, language="html")
            else:
                st.error("Error generating HTML/CSS.")
    else:
        st.warning("Please upload an image.")

Conclusion

With this setup, you’ve created a pipeline that not only automates the analysis of UI images but also translates them into HTML and CSS. This workflow is a major time-saver for developers, designers, and anyone involved in UI design. Now, you can turn visual ideas into functional code with the power of AI!

Building a Multi-Turn-Assistant Application using Llama, Claude and GPT4o

Aryan Kargwal — Fri, 18 Oct 2024 17:32:13 +0000

💻Github: https://github.com/aryankargwal/genai-tutorials/tree/main/multi-turn-agents
🎥Youtube: https://youtu.be/S9iHpExFrTs

In this guide, we’ll explore the development of a multi-turn AI assistant application using LLMs and AI assistant integration. This application is designed to streamline complex workflows such as internet retrieval, market research, campaign generation, and image creation. Throughout this process, we will rely on Tune Studio for AI model orchestration, and Streamlit for the front-end user interface. The end goal is to create a fully automated assistant-led pipeline that performs end-to-end tasks by interacting with multiple AI assistants in a sequential manner—also known as a multi-turn workflow.

What is a Multi-Turn AI Assistant Application?

In the context of AI and automation, a multi-turn assistant application is one where multiple interactions (or "turns") are required to complete a task. The application maintains context throughout these turns and allows each assistant or model to perform specific sub-tasks in a coordinated manner. This approach contrasts with single-turn applications, where the AI assistant addresses a single user query without needing to track prior inputs or outputs.

In this tutorial, the multi-turn approach allows AI assistants to collaborate across multiple steps:

Market Research Assistant gathers data from the web.
Analytics Assistant processes the research and generates insights.
Campaign Generation Assistant creates marketing strategies.
Image Generation Assistant produces a campaign poster.

Each assistant plays a crucial role and passes context to the next in line, ensuring a smooth and coherent user experience.

What Are AI Assistants?

AI assistants are digital agents powered by machine learning models that help users perform tasks, answer questions, and provide recommendations. Unlike co-pilots or AI agents, AI assistants focus on assisting with user-driven tasks, such as scheduling meetings, performing web searches, or, in our case, handling marketing tasks.

There are three distinct categories of LLM-driven tools:

AI Assistants: Designed to respond to user commands and requests. Common examples include virtual assistants like Siri or Alexa, but they can also handle more specialized workflows.
Co-Pilots: These tools work alongside humans, helping improve tasks as they are being performed. Examples include Grammarly for writing and GitHub Copilot for coding.
AI Agents: Autonomous agents that perform tasks without user input, such as ReACT or Agentic Workflows.

In our application, the AI assistants are key players in achieving each part of the task while ensuring user control and input at every step. Now, let’s break down how we’ve integrated multiple assistants to create a seamless marketing and campaign generation tool.

Step-by-Step Breakdown of the Application

1. Performing Market Research with an AI Assistant

In this first step, the AI assistant is responsible for gathering relevant information from the internet. We use a Llama 3.1 model fine-tuned for research tasks to collect numerical data, trends, and insights from across the web.

Here’s the core code for this assistant's function:

def call_market_research_assistant(query):
    payload = {
        "temperature": 0.8,
        "messages": [{"role": "user", "content": query}],
        "model": "kargwalaryan/research",
        "stream": False,
        "frequency_penalty": 0,
        "max_tokens": 100
    }
    response = requests.post(research_url, headers=headers, data=json.dumps(payload))
    return response.json()

This function sends a user query to the Tune Studio API, which uses a fine-tuned model to fetch relevant market research. The model acts as a subject matter expert on the specific topic or product the user inquires about.

2. Analyzing Research and Creating Insights

Once the data is gathered, the next assistant steps in to analyze the research. This assistant is run using Claude Sonnet, a model known for its compliance, safety, and conversational adaptability.

def call_analytics_assistant(research_text):
    user_content = f"Here is some market research data: {research_text}. Extract all the marketing insights and generate a campaign prompt."

    payload = {
        "temperature": 0.9,
        "messages": [
            {"role": "system", "content": "You are TuneStudio"},
            {"role": "user", "content": user_content}
        ],
        "model": "anthropic/claude-3.5-sonnet",
        "stream": False,
        "frequency_penalty": 0.2,
        "max_tokens": 300
    }
    response = requests.post(research_url, headers=headers, data=json.dumps(payload))
    return response.json()

Here, the Claude Sonnet model processes the research and extracts stylistic and strategic insights that will inform the next step—campaign generation.

3. Generating the Marketing Campaign

For campaign generation, we need an assistant that not only understands the market analysis but can also create a compelling, structured campaign. The Claude Sonnet model shines in this area, as it generates an engaging and compliant campaign strategy based on market trends.

def generate_campaign(analysis_text):
    payload = {
        "temperature": 0.9,
        "messages": [
            {"role": "system", "content": "Generate a marketing campaign based on this analysis: {analysis_result}."}
        ],
        "model": "kargwalaryan/campaign-gen",
        "stream": False,
        "frequency_penalty": 0.2,
        "max_tokens": 150
    }
    response = requests.post(research_url, headers=headers, data=json.dumps(payload))
    return response.json()

This assistant pulls from the insights gathered and creates a comprehensive campaign that could be deployed over the next few months.

4. Image Generation for the Campaign Poster

The final assistant in this pipeline generates a visual representation—a campaign poster—using GPT4o. This model specializes in image creation tasks based on textual descriptions.

def call_image_generation(analysis_text):
    payload = {
        "temperature": 0.9,
        "messages": [
            {"role": "system", "content": "Generate a campaign poster based on this analysis: {analysis_result}"}
        ],
        "model": "kargwalaryan/image-gen",
        "stream": False,
        "frequency_penalty": 0.2,
        "max_tokens": 100
    }
    response = requests.post(research_url, headers=headers, data=json.dumps(payload))
    return response.json()

This model generates a creative campaign poster based on the strategy developed in the earlier steps, completing the entire marketing pipeline.

Why Use Multi-Turn Assistant Workflows?

Multi-turn workflows allow for complex tasks to be broken into smaller, manageable operations, each handled by a specialized AI assistant. This ensures that the final output is not only accurate but also aligned with the user's overall goals.

Some of the key advantages of multi-turn workflows include:

Context Retention: The application retains context across different stages of the workflow. This allows each assistant to build upon the work of previous assistants.
Task Specialization: Each assistant is optimized for a specific sub-task, ensuring higher performance in individual areas like research, analysis, campaign generation, and image creation.
Flexibility and Customization: You can easily modify or swap out assistants to suit different applications. For example, you could replace the market research assistant with one better suited to another industry or domain.

Conclusion

Creating a multi-turn AI assistant application allows you to harness the power of multiple LLMs and assistants to handle complex tasks in a highly structured way. By breaking down tasks into distinct stages and integrating models like Llama 3.1, Claude Sonnet, and GPT4o, you can build intelligent, autonomous pipelines that help users with everything from market research to visual content creation.

This approach is ideal for applications where tasks need to be completed in a step-by-step manner while maintaining context across all steps.

Doing Multihop on HotPotQA Using Qwen 2.5 72B

Aryan Kargwal — Thu, 26 Sep 2024 14:46:21 +0000

When dealing with complex question-answering tasks, a single-hop retrieval approach might not be enough. Questions often require synthesizing information from multiple sources. That’s where MultiHop Question Answering (QA) comes into play, requiring more advanced tools for retrieval and reasoning. In this post, I’ll describe how I built a multi-hop QA pipeline using DSPy, ColBERT, TuneAPI, and Qwen 2.5 72B to handle multi-step reasoning over a knowledge base.

Understanding the Key Tools

Before diving into the code, let’s first break down the key tools and libraries that power this pipeline:

1. DSPy (Data Structure Processing)

DSPy is a Python library that helps structure multi-step processes for tasks like retrieval-augmented generation and multi-hop question answering. It allows us to define a clear, modular flow for handling complex information retrieval tasks and integrate language models effectively.

2. ColBERT (Contextualized Late Interaction over BERT)

ColBERT is a dense retrieval model designed to retrieve passages efficiently from large corpora. It works by encoding both the query and documents in a low-dimensional space and comparing them to find relevant matches. For multi-hop QA, ColBERT helps identify the most pertinent passages to answer complex questions.

3. TuneAPI (API Proxy for LLMs)

TuneAPI acts as a proxy API to interact with LLMs such as Qwen. This lets us access the powerful inference capabilities of LLMs and customize how they process inputs and generate responses.

4. Qwen 2.5 72B (Alibaba’s Vision-Language Model)

Qwen 2.5 72B is a state-of-the-art large language model developed by Alibaba. While it’s primarily known for its vision-language tasks, Qwen excels in natural language reasoning, making it a great choice for multi-hop QA tasks where nuanced reasoning over text is required.

5. HotPotQA (Dataset for Multi-Hop QA)

HotPotQA is a dataset designed specifically for multi-hop question answering. It contains questions that require information from multiple documents to arrive at an accurate answer, making it ideal for training and evaluating multi-hop QA systems.

Setting Up the MultiHopQA Pipeline

The goal here is to build an end-to-end pipeline that can retrieve relevant documents using ColBERT, pass the retrieved contexts to Qwen 2.5 72B for reasoning, and finally output the predicted answer.

Code Walkthrough

Let’s break down the process into manageable steps. Here’s the code for building the pipeline:

1. Importing Required Libraries

import requests
from dsp import LM
from dspy.datasets import HotPotQA
import dspy
from dsp.utils import deduplicate

We start by importing necessary libraries: DSPy for data handling, ColBERT for retrieval, and requests to interact with the TuneAPI. The HotPotQA dataset is also loaded to provide multi-hop questions for the pipeline.

2. Creating a Custom Language Model Client

To use Qwen, we need a custom class to handle API requests. We interact with Qwen via the TuneAPI to submit prompts and retrieve responses.

class CustomLMClient(LM):
    def __init__(self, model, api_key):
        self.model = model
        self.api_key = api_key
        self.base_url = "https://proxy.tune.app/chat/completions"
        self.history = []
        self.kwargs = {}

    def basic_request(self, prompt: str, **kwargs):
        headers = {
            "Authorization": f"{self.api_key}",
            "Content-Type": "application/json"
        }
        data = {
            "model": self.model,
            "messages": [
                {"role": "system", "content": "You are TuneStudio, answer the question based on the context given to you."},
                {"role": "user", "content": prompt}
            ],
            "temperature": kwargs.get("temperature", 0.9),
            "max_tokens": kwargs.get("max_tokens", 100),
            "frequency_penalty": kwargs.get("frequency_penalty", 0.2),
            "stream": kwargs.get("stream", False)
        }
        response = requests.post(self.base_url, headers=headers, json=data)
        return response.json()

custom_lm = CustomLMClient(model='qwen/qwen-2.5-72b', api_key='your_api_key_here')

This class wraps around the Qwen model and formats the prompt, handles API communication, and processes the response. The basic_request method takes care of sending requests to the TuneAPI.

3. Configuring Retrieval and Language Model

Next, we configure ColBERT and set up DSPy to use our custom language model client for inference.

colbertv2_wiki17_abstracts = dspy.ColBERTv2(url='http://20.102.90.50:2017/wiki17_abstracts')
dspy.settings.configure(lm=custom_lm, rm=colbertv2_wiki17_abstracts)

Here, ColBERTv2 retrieves relevant Wikipedia abstracts. These abstracts will be passed to the language model for deeper reasoning.

4. Loading HotPotQA Dataset

dataset = HotPotQA(train_seed=1, train_size=20, eval_seed=2023, dev_size=50, test_size=0)
trainset = [x.with_inputs('question') for x in dataset.train]
devset = [x.with_inputs('question') for x in dataset.dev]

We load a small subset of the HotPotQA dataset for testing. This dataset will provide multi-hop questions for the pipeline.

5. Simplified Baleen for Multi-Hop Retrieval

The Simplified Baleen class handles the multi-hop retrieval process. It repeatedly retrieves passages, feeds them into the language model, and finally generates an answer.

class SimplifiedBaleen(dspy.Module):
    def __init__(self, lm_client, passages_per_hop=3, max_hops=1):
        super().__init__()
        self.retrieve = dspy.Retrieve(k=passages_per_hop)
        self.max_hops = max_hops
        self.lm_client = lm_client

    def generate_query(self, context, question, **kwargs):
        query = f"{question} Context: {' '.join(context)}"
        return query

    def generate_answer(self, context, question, **kwargs):
        context_str = " ".join(context)
        prompt = f"Given the following information: {context_str} \n\nAnswer the question: {question}"
        response = self.lm_client(prompt, **kwargs)
        return response[0]

    def forward(self, question, **kwargs):
        context = []
        for _ in range(self.max_hops):
            query = self.generate_query(context, question, **kwargs)
            passages = self.retrieve(query).passages
            context = deduplicate(context + passages)
        answer = self.generate_answer(context, question, **kwargs)
        return dspy.Prediction(context=context, answer=answer)

This is the core of our pipeline. It:

Generates queries based on previously retrieved context.
Retrieves relevant documents using ColBERT.
Passes the final context to Qwen to generate the answer.

6. Running the Pipeline

We define a question and pass it through the pipeline to retrieve the answer.

my_question = "What position on the Billboard Top 100 did Alison Moyet's late summer hit achieve?"
uncompiled_baleen = SimplifiedBaleen(lm_client=custom_lm)
pred = uncompiled_baleen(my_question, temperature=0.9, max_tokens=100)

print(f"Question: {my_question}")
print(f"Predicted Answer: {pred.answer}")

Boss Llama: Building a Smart Interview Simulator using Llama 3.1 70B

Aryan Kargwal — Thu, 22 Aug 2024 17:22:20 +0000

Moving a bit further from writing and exploring the world of LLMs as just a consumer of the vast knowledge and context awareness, I took it upon myself to build a product out of these tools. Boss Llama is an interactive intelligent interview simulator on Meta's Llama 3.1 70B.

Although not a novel implementation, I hope my tutorial helps you understand the various API calls and functions involved in processing chat, inputs, and data files in a Streamlit Web Application using Tune Studio to deploy our model and set API gateways for inference. So, let's look at how you can replicate the same results.

The Model: Llama 3.1 70B

An Open Source LLM, Meta's Llama 3.1 70B, has good reasons to become my choice for the product. By improving the context window from 8K to 128K from its predecessor, Llama 3 70B, the model also brings a more significant threshold for output tokens, 4096, over the previous 2048 context.

Analysis taken from Aritificial Analysis

Earlier, however, I had tried implementing a locally hosted Llama 3.1 8B for the task, which unfortunately lacks the context windows expected off of the use-case, which typically involves more extended exchanges averaging about 1500-2000 words or 2000+ tokens. So let us now check out how you can also make such an application.

Implementation

Regarding the implementation, we have chosen Streamlit as the base of our operations, helping us tie up the outputs generated by the API calls to a chat interface. Unfortunately, the larger model asks for a higher VRAM, which I have chosen to fulfill using Tune Studio's API Calls.

While discussing the code, however, we will skip over the Streamlit part and focus on its API aspect. If you wish to see how I implement that, check out my video tutorial on YouTube here or head over to the Github Repository here!

For the upcoming code, here are some essential variables:

Conversation: A session state variable holding all the conversation exchanges between the bot and the user.
Difficulty: The difficulty of the simulated interview
API Key: Your Tune Studio API Key
Max Questions: Number of Questions in the Interview

System Prompt

Finetuning is the best way to get a model to perform exactly how you want it to; well, I went for the next best thing: a thoughtful and thorough system prompt. While choosing the system prompt, we should be detailed with our requirements, as the model tends to meander and hallucinate if such instructions are not given.

The latest adversarial training on the modern Llama models also allows us to pass such a system prompt, avoiding any prompt leakage.

You are Boss Llama, an advanced AI interviewer. Your goal is to conduct a comprehensive and intelligent interview with the candidate based on the following details:

1. Job Description: {st.session_state.job_description}
2. Difficulty Level: {difficulty}
3. Number of Questions: {st.session_state.max_questions}

Instructions:
1. Start the Interview:
   - Begin by presenting a detailed job description for the role based on the difficulty level and the provided job description. Try to keep this introduction small and to the point as the user already knows what they are interviewing for.
   - Provide a warm welcome message to start the interview and set a positive tone.
2. Generate and Ask Questions:
   - Ask a series of questions, up to the specified number of questions. Ensure these questions are relevant to the job description and appropriately challenging according to the difficulty level.
   - Provide clear and concise prompts that assess the candidate's skills, knowledge, and fit for the role.

3. Conduct the Interview:
  - Engage with the candidate in a conversational manner. If the candidate's responses are vague or insufficient, let them know about it and give them a chance to improve, but count it as one more question.
   - Maintain a professional and supportive tone throughout the interview.

Generating Responses

We will generate the responses and the conversation using a curl command from Tune Studio. The command is a simple way of linking your current working code with a model of your choice on Tune Studio, which holds an amazingly massive library of free models for inference and even more advanced models with custom fine-tuning and deploying practices for hard-core enthusiasts.

The variable "conversation," which incrementally holds the ongoing conversation, is called every time to create a response that adds to the existing discussion.

With parameters such as temperature, frequency_penaly, and max_tokens, we can also tweak the quality of responses, further enhancing the feeling of being interviewed by a proper interviewer.

# Function to call the API
def generate_response(conversation, apikey):
    url = "https://proxy.tune.app/chat/completions"
    headers = {
        "Authorization": apikey,  # Your API key
        "Content-Type": "application/json"
    }

    # Construct the payload for the API call
    payload = {
        "temperature": 0.9,
        "messages": conversation,
        "model": "meta/llama-3.1-70b-instruct",
        "stream": False,
        "frequency_penalty": 0.2,
        "max_tokens": 500
    }

    # Send the POST request to the API
    response = requests.post(url, headers=headers, data=json.dumps(payload))

    # Check if the request was successful
    if response.status_code == 200:
        # Extract the response from the JSON output
        return response.json()["choices"][0]["message"]["content"]
    else:
        return f"Error: {response.status_code} - {response.text}"

Generate Evaluations

For the evaluations, we are using a similar API call. We only pass the individual exchanges from the bot and the user to run an assessment using a suitable system prompt.

This second call activates the interviewer's harsher and more intense side. This new call then looks at the conversation from a third perspective and assigns feedback and a score that feeds back into the web application.

# Function to generate evaluations on the interview
def generate_evaluation(question, answer, difficulty, apikey):
    url = "https://proxy.tune.app/chat/completions"
    headers = {
        "Authorization": apikey,
        "Content-Type": "application/json"
    }

    payload = {
        "temperature": 0.7,
        "messages": [
            {"role": "system", "content": f"Evaluate the following answer based on the job description difficulty level: {difficulty}."},
            {"role": "user", "content": f"Question: {question}\nAnswer: {answer}"}
        ],
        "model": "meta/llama-3.1-70b-instruct",
        "stream": False,
        "frequency_penalty": 0.2,
        "max_tokens": 500
    }

    try:
        response = requests.post(url, headers=headers, data=json.dumps(payload))
        response.raise_for_status()
        result = response.json()
        feedback = result.get("choices", [{}])[0].get("message", {}).get("content", "No feedback provided")
        score = result.get("choices", [{}])[0].get("score", 0)
        return feedback, score
    except requests.RequestException as e:
        return f"Error: {e}", 0

Download PDF Report

Well, finally, what good is progress in AI? Suppose all we are doing is asking it to write our assignment. In that case, the final function links the outputs generated by the Evaluation function to FPDF to generate a plausible and downloadable PDF for the evaluation.

What is FPDF, you ask? FPDF, initially a PHP class, is a library used for PDF document generation under Python. Compared to other jargon available online, FPDF provides a more streamlined and straightforward way to generate PDFs. (It also allows us to add PNGs, JPEGs, and GIFs to the PDF, which should be a boon if we wish to add systems to include tacky diagrams in the report.)

# Function to generate a PDF report
def generate_pdf_report(evaluations):
    pdf = FPDF()
    pdf.add_page()
    pdf.set_font("Arial", size=12)

    pdf.cell(0, 10, "Interview Evaluation Report", ln=True, align="C")
    pdf.ln(10)  # Add a line break

    for evaluation in evaluations:
        pdf.set_font("Arial", style='B', size=12)
        pdf.multi_cell(0, 10, evaluation["Question"])
        pdf.set_font("Arial", size=12)
        pdf.multi_cell(0, 10, evaluation["Answer"])
        pdf.multi_cell(0, 10, f"Feedback: {evaluation['Feedback']}")
        pdf.multi_cell(0, 10, f"Score: {evaluation['Score']}")
        pdf.ln(5)  # Add a line break

    # Save the PDF to a temporary file
    temp_file = tempfile.NamedTemporaryFile(delete=False, suffix=".pdf")
    pdf.output(temp_file.name)
    return temp_file.name

Conclusion

Here, we saw an implementation of Llama 3.1 70B in a Streamlit Web Application to simulate brilliant interviews using a chat interface. Although the final product lacks some accessibility features such as TTS or STT, it shows great promise in the way even a model that is not fine-tuned can operate using just system prompts.

How to do efficient fine-Tuning for LLMs using SLoRA

Abhishek Mishra — Wed, 07 Aug 2024 08:23:17 +0000

You're a passionate AI developer, eager to try to utilize the power of large language models (LLMs) for your latest project. You've got brilliant ideas, but there's a catch – fine-tuning these massive models feels like trying to parallel park a cruise ship in a crowded marina. It's resource-intensive, time-consuming, and frankly, a bit overwhelming.
Sound familiar? You're not alone in this boat.

Before we dive deeper, let's clarify what we mean by fine-tuning:

Fine-tuning is the process of further training a pre-trained model on a specific task or dataset to adapt its knowledge for a particular application.

The world of AI has been grappling with a significant challenge: how to efficiently fine-tune LLMs without breaking the bank or melting your hardware – we all are GPU poor except NVIDIA.
Traditional fine-tuning methods are like using a sledgehammer to crack a nut, – they get the job done, but at what cost?
Enter SLoRA – Sparse Low-Rank Adaptation, – the unsung hero for efficient model fine-tuning.

Fine-tuning large language models (LLMs) has become a crucial step in achieving state-of-the-art results in various natural language processing (NLP) tasks. However, this process often comes with significant computational costs, memory requirements, and time constraints. In this article, we'll explore SLoRA, a novel approach to efficient model fine-tuning that promises to revolutionize the way we work with LLMs. By leveraging sparse low-rank adaptation, SLoRA offers a faster, more cost-effective, and more sustainable way to fine-tune LLMs without sacrificing performance.

What is SLoRA?

To understand SLoRA, it's essential to first grasp the concept of Low-Rank Adaptation (LoRA). LoRA is a parameter-efficient fine-tuning method that updates only a small subset of model parameters while keeping the rest frozen. This approach has shown remarkable success in reducing computational costs and memory requirements for model fine-tuning.

However, LoRA still updates a relatively large number of parameters, which can be computationally expensive and memory-intensive. This is where SLoRA comes in – by introducing sparsity into the LoRA framework, SLoRA further reduces the number of updated parameters to approximately 1% of the original model's parameters. This drastic reduction in updated parameters leads to significant computational savings and faster convergence rates
SLoRA stands for Sparse Low-Rank Adaptation, a method designed to enhance the efficiency of fine-tuning LLMs. It builds on the concept of LoRA, which constrains the update of pre-trained weights using low-rank decomposition. SLoRA introduces sparsity into this approach, focusing only on a subset of parameters that significantly impact the model's performance.

Here's a simple analogy -- Imagine you have a giant jigsaw puzzle. LoRA would focus on updating a specific section of the puzzle, while SLoRA would pinpoint only the most important pieces within that section.

How SLoRA Works?

SLoRA employs a sparse matrix approach where the weight updates are constrained to a low-rank format and further sparsified. This involves decomposing the weight matrix into a product of two smaller matrices and applying updates only to a sparse subset of the original parameters. This method reduces the density of updates to about 1%, significantly cutting down on the resources needed for training.

Think of a weight matrix in an LLM as a giant grid of numbers. These numbers represent the connections between different parts of the model. SLoRA uses a technique called sparse matrix decomposition to break down this grid into smaller, more manageable pieces.

Imagine slicing a pizza into smaller triangles. SLoRA only updates the toppings on a select few of those triangles, leaving the rest untouched. This dramatically reduces the amount of data we need to process and store.

Comparison with Traditional Fine-Tuning Methods

Traditional fine-tuning involves updating all model parameters, which is resource-intensive and time-consuming. In contrast, SLoRA updates only a small, significant subset of parameters, achieving similar performance with much lower computational overhead.

SLoRA in the nutshell:

SLoRA builds on the foundation of LoRA (Low-Rank Adaptation), which already constrains updates to a small subset of parameters.
It takes this a step further by introducing sparsity – focusing on an even smaller, more crucial set of parameters.
The result? You're updating only about 1% of the model's parameters, dramatically reducing computational load and memory requirements.

Benefits:

Reduced Computational Requirements: By updating only a sparse subset of parameters, SLoRA dramatically lowers the computational load.
Faster Fine-Tuning Process: The sparse updates enable quicker convergence, speeding up the fine-tuning process.
Lower Memory Usage: The reduced number of updates translates to lower memory requirements, making it feasible to deploy models on devices with limited memory.
Potential for Improved Model Performance: Efficient parameter updates can lead to models that are not only faster but also potentially more robust and adaptable to specific tasks.

How to use SLoRA in Your Projects?

Initialize the Sparse Matrix: Begin by setting up the sparse matrix with low-rank decomposition.
Apply Sparse Updates: Update only the critical parameters as identified by the sparsity constraints.
Train the Model: Proceed with the fine-tuning process, leveraging the computational efficiency of SLoRA.

For more detailed guide checkout this paper: https://arxiv.org/pdf/2308.06522

SLoRA's Secret Sauce:

Here's where SLoRA really flexes its muscles. By dramatically reducing the number of parameters updated during fine-tuning, SLoRA processes fewer tokens. It's like having a car that can drive the same distance using only a fraction of the fuel.

Fewer tokens processed = Lower costs
Efficient updates = More bang for your buck
Optimized token usage = Stretch your budget further

Let's say you're fine-tuning a model on a specific task. Traditional methods might process millions of tokens, updating every parameter. With SLoRA, you're looking at a fraction of that - potentially cutting your token usage (and thus, your costs)!

Conclusion

SLoRA represents a significant leap forward in efficient model fine-tuning. It empowers developers to unlock the full potential of LLMs while being mindful of resources and costs.

Ready to give SLoRA a try? At Tune AI, we implemented this approach to, make models mode accessible and provide an efficient way to fine-tune and serve LLMs.
