Conversational AI Agent for SME Executive

 

                                                                generated by metaai

Use Case:

Consider Management Consulting companies like McKinsey, PwC or BCG.

They consult with large scale enterprises in driving growth.

For example, Dabur India has hired PwC to consult, the goal is to grow their Revenue from 12,000 crores (In FY 24) to 20,000 crores (In FY 28) in 4 years. 66% CAGR

To achieve this they have to transform various functions of their business, like Enhanced Sales Operations, Efficient Supply Chain, Optimize Manufacturing, Cost Reduction in Procurement etc.

These strategies shall be driven by Individual Resources who head this function.

In the current scenario, Expert SME's conduct detailed assessments through interviews of key personnel from Top like CEO, CFO, COO about the skills required by the above mentioned Individual Resources to achieve this.

For example, optimizing operations is the responsibility of the COO. They interview the CFO and ask him about how the current skills (based on a baseline logic or SOP) is aligned with the strategy defined. This is to evaluate the COO on the skills required by him for the job to be done (which is optimizing operations).

We need an AI Agent to replace the interview done by the SME's, instead of SME's COO will talk to agent and assessment would be done.

We have a standard dataset of relevant questions, the context of these questions, scoring logic based on the responses.

We need an AI Agent to dynamically ask questions during the assessment to find the logical answers which will be then converted to a score.

Creating an end-to-end conversational AI agent for this use case involves several components:

1. Natural Language Processing (NLP) Model: To understand and generate human-like responses.

2. Knowledge Base: Contains standard datasets of relevant questions, context, and scoring logic.

3. Dialogue Manager: To manage the flow of conversation and dynamically ask relevant questions.

4. Scoring Engine: To evaluate the responses and generate a score based on predefined logic.

5. Interface: A user-friendly interface for the COO to interact with the AI agent.

Here is a high-level overview of the steps involved:

1. Data Preparation

- Collect Standard Questions: Gather all the questions used by SMEs during the interviews.

- Define Context and Scoring Logic: Clearly define the context for each question and the scoring mechanism.

2. NLP Model

- Select NLP Framework: Use a pre-trained model like GPT-4, BERT, or similar.

- Fine-Tune the Model: Fine-tune the model with your dataset of questions and expected responses to improve its understanding and generation capabilities.

3. Knowledge Base

- Create a Knowledge Base: Store all the questions, context, and scoring logic in a structured format (e.g., a database).

4. Dialogue Manager

- Develop Dialogue Manager: Create a module to handle the flow of the conversation. This involves selecting the next question based on previous responses and the context.

5. Scoring Engine

- Implement Scoring Engine: Develop a system to evaluate responses and generate a score. This can be based on keyword matching, semantic similarity, or other NLP techniques.

6. Interface

- Build User Interface: Create a user-friendly interface for the COO to interact with the AI agent. This could be a web or mobile application.

Detailed Steps

```python

# Import necessary libraries

import openai

import json

# Initialize OpenAI API (assuming you are using GPT-4)

openai.api_key = 'your-openai-api-key'

# Sample knowledge base (a simplified example)

knowledge_base = {

    "questions": [

        {

            "id": 1,

            "question": "How would you describe the current efficiency of the supply chain?",

            "context": "Supply Chain Efficiency",

            "scoring_logic": "response should mention specific metrics like lead time, cost, and reliability."

        },

        # Add more questions here

    ],

    "scoring": {

        "lead time": 10,

        "cost": 10,

        "reliability": 10

        # Add more scoring criteria here

    }

}

# Dialogue Manager

class DialogueManager:

    def __init__(self, knowledge_base):

        self.knowledge_base = knowledge_base

        self.current_question = 0

    def get_next_question(self):

        if self.current_question < len(self.knowledge_base["questions"]):

            question = self.knowledge_base["questions"][self.current_question]

            self.current_question += 1

            return question["question"]

        else:

            return None

    def score_response(self, response, context):

        score = 0

        for criterion, points in self.knowledge_base["scoring"].items():

            if criterion in response:

                score += points

        return score

# Instantiate dialogue manager

dialogue_manager = DialogueManager(knowledge_base)

# Function to handle conversation

def handle_conversation(response):

    current_question = dialogue_manager.get_next_question()

    if current_question:

        print(f"AI Agent: {current_question}")

        # Assuming `response` is the user's response to the question

        score = dialogue_manager.score_response(response, current_question)

        print(f"Score: {score}")

    else:

        print("AI Agent: Thank you for your responses. The assessment is complete.")

# Example interaction

response = "Our supply chain has an average lead time of 5 days, costs are within budget, and reliability is above 95%."

handle_conversation(response)

```

Integration

1. Backend: Set up a backend server to handle API requests and manage state.

2. Frontend: Create a web or mobile interface for user interaction.

3. Deploy Model: Deploy the NLP model and integrate it with the dialogue manager and scoring engine.

4. Testing and Refinement: Test the system with real users and refine the model and logic based on feedback.

By following these steps, you can develop a conversational AI agent that effectively replaces SME interviews and dynamically assesses the skills of individual resources in a consulting scenario.

TensorRT-Specific LLM Optimizations for Jetson (NVIDIA Edge AI)

 

🚀 TensorRT-Specific LLM Optimizations for Jetson (NVIDIA Edge AI)

TensorRT is NVIDIA’s deep learning optimizer that dramatically improves inference speed for LLMs on Jetson devices. It enables:
✅ Faster inference (2-4x speedup) with lower latency.
✅ Lower power consumption on edge devices.
✅ Optimized memory usage for LLMs.

---

1️⃣ Install TensorRT & Dependencies

First, install TensorRT on your Jetson Orin/Nano:

2️⃣ Convert LLM to TensorRT Engine

TensorRT requires models in ONNX format before optimization.

Convert GGUF/Quantized Model → ONNX

First, convert your LLaMA/Mistral model to ONNX format:

python convert_to_onnx.py --model model.gguf --output model.onnx

(Use onnx_exporter.py from Hugging Face if needed.)

---

3️⃣ Optimize ONNX with TensorRT

Use trtexec to compile the ONNX model into a TensorRT engine:

trtexec --onnx=model.onnx --saveEngine=model.trt --fp16

🔹 --fp16: Uses 16-bit floating point for speed boost.
🔹 --saveEngine: Saves the optimized model as model.trt.

---

4️⃣ Run Inference Using TensorRT-Optimized LLM

Now, run the optimized .trt model with TensorRT:

import tensorrt as trt
import numpy as np

# Load TensorRT model
TRT_LOGGER = trt.Logger(trt.Logger.WARNING)
runtime = trt.Runtime(TRT_LOGGER)
with open("model.trt", "rb") as f:
    engine = runtime.deserialize_cuda_engine(f.read())

def infer_tensorrt(input_text):
    # Preprocess input, run inference, and return response
    return "AI Response from TensorRT model"

print(infer_tensorrt("What is Edge AI?"))

---

5️⃣ Deploy as a FastAPI Edge AI Agent

Run a FastAPI-based chatbot on Jetson:

from fastapi import FastAPI
import subprocess

app = FastAPI()

@app.get("/ask")
def ask(question: str):
    cmd = f'./main --engine model.trt -p "{question}" -n 100'
    response = subprocess.check_output(cmd, shell=True).decode()
    return {"response": response}

# Run API: uvicorn app:app --host 0.0.0.0 --port 8000

---

🔥 Benchmark TensorRT vs. CPU/GPU Performance

Compare TensorRT vs. CPU vs. GPU inference speed:

trtexec --loadEngine=model.trt --benchmark

💡 Expected Speedup:
🚀 TensorRT (2-4x faster) > CUDA (cuBLAS) > CPU (Slowest)

---

📌 Conclusion

✅ TensorRT accelerates LLM inference on Jetson Edge AI.
✅ Use ONNX + TensorRT Engine to optimize LLaMA/Mistral models.
✅ Deploy as a FastAPI agent for real-time inference.

• Select a framework (GGUF, ONNX, TFLite).
• Deploy on an Edge AI device (Jetson, Raspberry Pi, NPU-based system).
• Optimize with quantization & acceleration (GPTQ, TVM, TensorRT).

Step-by-Step Guide to Deploy an LLM-Based AI Agent on Edge AI

We will set up a lightweight LLM (Phi-3 Mini, TinyLlama, or Mistral 7B quantized) on an Edge AI device (Jetson Orin, Raspberry Pi 5, or Intel NPU).

---

🛠 Step 1: Choose the Hardware

Based on our compute power and use case, select one:

• 🔹 Raspberry Pi 5 – Best for basic NLP tasks with a quantized model (TinyLlama, Phi-3).
• 🔹 NVIDIA Jetson Orin/Nano – For running LLMs with TensorRT acceleration.
• 🔹 Intel NPU (Neural Compute Stick 2) – If we need low-power deep learning inference.

For this guide, I’ll assume Raspberry Pi 5 (but can modify for Jetson/Intel if needed).

---

🛠 Step 2: Install Dependencies

1️⃣ Update & Install Required Packages

sudo apt update && sudo apt upgrade -y
sudo apt install -y python3-pip git wget curl

2️⃣ Install PyTorch (Optimized for Edge)

pip install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cpu

For Jetson, install the NVIDIA JetPack SDK.

3️⃣ Install Llama.cpp (for running quantized models)

git clone https://github.com/ggerganov/llama.cpp
cd llama.cpp
make

---

🛠 Step 3: Download a Lightweight LLM (Phi-3, TinyLlama, Mistral 7B Quantized)

🔹 For Phi-3 Mini (2.7B) or TinyLlama (1.1B)

wget -O model.gguf https://huggingface.co/microsoft/Phi-3-mini-4bit-GGUF/resolve/main/model.gguf

🔹 For Mistral 7B (Quantized, 4-bit GGUF)

wget -O model.gguf https://huggingface.co/TheBloke/Mistral-7B-GGUF/resolve/main/mistral-7b-instruct-v0.2.Q4_K_M.gguf

---

🛠 Step 4: Run the Model on the Edge Device

🔹 Run the model using llama.cpp for fast inference

./main -m model.gguf -p "Hello, how can I assist you?" -n 100

• -m model.gguf → Load the model
• -p "Hello..." → Prompt
• -n 100 → Limit response tokens

🔹 If using Jetson, optimize with TensorRT

pip install tensorrt
python3 run_llm.py --use-tensorrt

---

🛠 Step 5: Create an AI Agent API with FastAPI

If we want a REST API for our AI agent, use FastAPI.

1️⃣ Install FastAPI & Uvicorn

pip install fastapi uvicorn

2️⃣ Create app.py

from fastapi import FastAPI
import subprocess

app = FastAPI()

@app.get("/ask")
def ask(question: str):
    cmd = f'./main -m model.gguf -p "{question}" -n 100'
    response = subprocess.check_output(cmd, shell=True).decode()
    return {"response": response}

# Run with: uvicorn app:app --host 0.0.0.0 --port 8000

3️⃣ Run the API

uvicorn app:app --host 0.0.0.0 --port 8000

Now, test with:

curl "http://localhost:8000/ask?question=What%20is%20Edge%20AI?"

---

🛠 Step 6: Optimize Performance

1️⃣ Use GGUF 4-bit Quantization (Already Applied)

• Reduces memory usage from 16GB to ~4GB.
• Keeps acceptable performance on Raspberry Pi.

2️⃣ Use ONNX Runtime (For Further Speed Boost)

pip install onnxruntime

Modify our script:

import onnxruntime as ort
session = ort.InferenceSession("model.onnx")

3️⃣ Use TensorRT (For NVIDIA Jetson)

sudo apt install nvidia-tensorrt

Run:

import tensorrt as trt

---

🚀 Final Outcome

• ✅ LLM-Based AI Agent Running on Edge
• ✅ Accepts Queries via REST API
• ✅ Optimized for Low-Power Devices

---

We can use Ollama for deploying an LLM-based agent on Edge AI, but it has higher hardware requirements. Here’s how it fits in:

---

🛠 Can We Use Ollama on Edge AI?

✅ Yes, but it depends on our hardware:

• 🟢 NVIDIA Jetson Orin/Nano → Ollama works with GPU acceleration (TensorRT).
• 🟢 Apple M1/M2/M3 (Mac) → Ollama runs natively with Metal acceleration.
• 🟡 Raspberry Pi 5 → Difficult but possible (must use a small 4-bit model).
• 🔴 Intel NPU (Neural Compute Stick 2) → Not recommended (Ollama lacks NPU support).

🔹 Ollama works best with GPUs (CUDA on Jetson, Metal on Mac).
🔹 If our Edge device has only CPU, Ollama may be too slow.

---

🛠 How to Install Ollama on Edge AI?

1️⃣ Install Ollama

curl -fsSL https://ollama.com/install.sh | sh

2️⃣ Check if It Works

ollama run mistral

3️⃣ Use a Lightweight Model (Phi-3, TinyLlama)

ollama pull microsoft/phi-3-mini
ollama run phi-3-mini

---

🛠 How to Run an AI Agent with Ollama (FastAPI API)

1️⃣ Install FastAPI

pip install fastapi uvicorn

2️⃣ Create app.py

from fastapi import FastAPI
import subprocess

app = FastAPI()

@app.get("/ask")
def ask(question: str):
    cmd = f'ollama run phi-3-mini "{question}"'
    response = subprocess.check_output(cmd, shell=True).decode()
    return {"response": response}

# Run: uvicorn app:app --host 0.0.0.0 --port 8000

3️⃣ Run the API

uvicorn app:app --host 0.0.0.0 --port 8000

4️⃣ Test the API

curl "http://localhost:8000/ask?question=What%20is%20Edge%20AI?"

---

🛠 When to Use Ollama vs. Llama.cpp

Feature	Ollama	Llama.cpp
GPU Acceleration	✅ Yes (CUDA, Metal)	❌ No
Easy Model Management	✅ Yes	❌ Manual
Lower RAM Usage	❌ High (8GB+)	✅ Low (4GB possible)
Faster Inference	✅ Yes (GPU)	🟡 Medium (CPU)

🔹 If using Jetson with GPU, Ollama is good.

🔹 If using Raspberry Pi 5 (only CPU), use llama.cpp instead.

🛠 Yes, We Can Quantize Ollama Models!

Quantization reduces memory and speeds up inference by using lower-bit precision (4-bit, 8-bit). Ollama itself does not support custom quantization, but we can convert and load quantized models manually.

---

🔥 Step 1: Convert an LLM to Quantized GGUF Format

Ollama models are in .mod format, but we can use llama.cpp to quantize them.

1️⃣ Install llama.cpp for Quantization

git clone https://github.com/ggerganov/llama.cpp
cd llama.cpp
make

2️⃣ Download a Pretrained Model (e.g., Phi-3, Mistral)

wget -O model.f16.gguf https://huggingface.co/microsoft/Phi-3-mini-GGUF/resolve/main/model.f16.gguf

3️⃣ Quantize to 4-bit (Q4_0)

./quantize model.f16.gguf model.q4_0.gguf q4_0

For even smaller models:

./quantize model.f16.gguf model.q8_0.gguf q8_0  # 8-bit

---

🔥 Step 2: Run the Quantized Model in Ollama

Now, Ollama does not natively support GGUF yet. But we can do this:

1️⃣ Convert GGUF to Ollama Format

ollama create phi-3-mini-q4 -m model.q4_0.gguf

(⚠️ If this fails, Ollama does not support direct GGUF loading. Use llama.cpp instead.)

2️⃣ Run the Quantized Model

ollama run phi-3-mini-q4

---

🔥 Step 3: Alternative - Run Quantized Model with llama.cpp

If Ollama cannot load the GGUF model, run it with llama.cpp:

./main -m model.q4_0.gguf -p "Explain Edge AI in simple words." -n 100

---

💡 When to Use Quantized Models?

Use Case	Best Option
Jetson Orin + GPU	Ollama with CUDA
Raspberry Pi 5 (CPU only)	llama.cpp with 4-bit quantization
Low RAM (≤4GB)	llama.cpp with Q4_0 models
Fastest Response (8GB+ RAM, Edge AI)	Ollama with 8-bit models

---

🚀 Final Answer

✅ We can quantize models for Edge AI
✅ Use llama.cpp for loading GGUF models
❌ Ollama does not support custom quantized GGUF directly

🚀 Is CUDA the Best Choice for Edge AI?

✅ CUDA is great for Edge AI, but only if our device has an NVIDIA GPU (like Jetson Orin/Nano).

🔥 Where Can CUDA Work?

Device	CUDA Supported?	Best Option
NVIDIA Jetson Orin/Nano	✅ Yes	TensorRT + CUDA
Desktop with NVIDIA GPU	✅ Yes	CUDA-accelerated Ollama/Llama.cpp
Apple M1/M2/M3 (Mac)	❌ No	Use Metal (Apple’s equivalent)
Raspberry Pi 5 (ARM CPU only)	❌ No	Use llama.cpp (CPU)
Intel NPU (Neural Compute Stick 2)	❌ No	Use OpenVINO or EdgeTPU

🔥 Best CUDA-Optimized LLM Setup for Edge AI (Jetson)

1️⃣ Install CUDA & cuDNN

sudo apt install nvidia-cuda-toolkit

2️⃣ Install TensorRT for Faster LLM Execution

sudo apt install libnvinfer-dev

3️⃣ Run llama.cpp with CUDA for Fast Inference

LLAMA_CUBLAS=1 make
./main -m model.q4_0.gguf -p "Explain Edge AI." -n 100

4️⃣ Optimize CUDA with TensorRT (Jetson only)

sudo apt install tensorrt

Then use a TensorRT-optimized model.

🔥 Should We Use CUDA for Edge AI?

✅ Yes, if we have an NVIDIA Jetson or GPU
❌ No, if we use Raspberry Pi or Intel NPU

For Jetson, CUDA + TensorRT is the best choice for LLMs.
For Raspberry Pi, use llama.cpp (CPU-only, quantized models).
