GenAI in Action: Real-World Applications and Strategic Implementation

(GenAI) is transforming industries by providing innovative solutions to complex problems. From low-code/no-code tools that democratize AI development to sophisticated model management strategies, GenAI is reshaping how businesses operate. Let’s delve into the practical applications of GenAI, with insights into managing models, real-world use cases, and strategic implementation.

Leveraging Low-Code/No-Code Tools

Low-code/no-code platforms are game-changers in the AI space. These tools empower non-technical users to build and deploy AI models with minimal coding, accelerating development cycles and reducing barriers to entry. However, for those with technical expertise, there are options to dive deeper into coding for more customized solutions.

Comparing Product Management and Model Management

Managing a product differs significantly from managing an AI model. Here’s a comparison:

Task Complexity: Model management involves intricate tasks such as data handling, training, and deployment, which can be more complex than traditional product management.
Performance Metrics: Unlike product management, which focuses on features and user experience, model management emphasizes accuracy, reliability, and continuous validation.

Case Study: Unilever's Food Waste Reduction Initiative

Unilever’s initiative to reduce food waste is a prime example of GenAI in action. This project, which went live in March, addresses “fridge blindness,” a common issue where consumers overlook items in their fridge, leading to waste. Key components of this solution include:

Vision and Recommendation Systems: These systems identify fridge items and suggest recipes based on available ingredients.
Data Integration and Validation: Ensuring consistent and reliable model outputs by integrating and validating data from various sources.

Practical Example: Mobile Phone Quality Evaluation

Consider a hypothetical scenario to illustrate GenAI applications further. Suppose you are the CTO of Cashify, a company specializing in mobile phone resale. You aim to automate the quality evaluation of mobile phones using vision models and large language models (LLMs).

Project Scope and Timeline:
Initial Estimation: The team estimates a timeline of 6-12 months for data collection and model training.
Accelerated Timeline: To meet a two-month deadline, the scope is narrowed to focus on specific mobile models with high resale value and common issues.
Data Readiness:
Conduct market research to identify models prone to faults.
Use historical data and pre-trained models to expedite the process.
Run a pilot with a select group of real-life users to gather initial data.
Model Development:
Vision Models: Develop models to detect physical damages, such as cracks and watermarks.
LLMs and Multimodal Models: Utilize models like GPT-4 to analyze textual and visual data for comprehensive quality assessment.
Integration and Testing: Ensure that the models can process images, identify damages, and provide accurate evaluations quickly.
Implementation Strategy:
Combine custom vision models, multimodal models, and historical data analysis to create a robust evaluation system.
Use a retrieval-augmented generation (RAG) approach to store and reference common issues, enhancing model accuracy and response time.

Exploring Tools and Use Cases in Customer Support for Food Delivery Platforms

food delivery platforms face numerous challenges in providing efficient and satisfactory customer support. This discussion highlights two significant use cases related to customer support, illustrating how implementing various tools can enhance the customer experience.

Use Case 1: Automating Common Inquiries with Chatbots

One of the most frequent issues in food delivery services is handling customer inquiries regarding order cancellations, refunds, and tracking statuses. Traditional customer support can be overwhelmed with these repetitive queries, leading to delayed responses and customer dissatisfaction.

Implementation Strategy:

Integration with Chatbots:
Rationale: Utilizing chatbots to handle repetitive inquiries can significantly reduce the load on human customer support agents. Chatbots can provide instant responses, improving customer satisfaction.
Process: Implement a chatbot system capable of fetching information from a pre-defined database of FAQs and support documents. For instance, if a customer asks about the cancellation process, the chatbot can retrieve the relevant information and provide a step-by-step guide.
Review Analysis and Feedback Improvement:
Rationale: Regularly analyzing customer reviews can identify common pain points and areas for improvement.
Process: Utilize natural language processing (NLP) tools to scan reviews from app stores and feedback forms. By categorizing and prioritizing feedback, companies can address the most critical issues promptly.
Example Implementation: A food delivery platform could use a chatbot integrated with a robust FAQ system. When a user inquires about canceling an order, the chatbot accesses the database, retrieves the relevant information, and responds: “You can cancel your order within the app before the restaurant starts preparing it. Please go to your orders, select the order you wish to cancel, and follow the prompts.”

Use Case 2: Enhancing Customer Support with Domain-Specific Models

Handling specific inquiries that require a deeper understanding of the product or service necessitates a more sophisticated approach. Domain-specific models can significantly enhance the accuracy and relevance of responses.

Implementation Strategy:

Domain-Specific Embeddings:
Rationale: Generic language models may not always understand the context-specific nuances of customer inquiries. Domain-specific embeddings can provide more accurate responses.
Process: Train embeddings on domain-specific data, such as customer support logs, product manuals, and industry-specific documents. For example, a model trained on food delivery data will better understand queries related to delivery times, order modifications, and payment issues.
Historical Data Utilization:
Rationale: Leveraging historical support data can improve the accuracy of responses and help predict future inquiries.
Process: Store historical support interactions in a vector database. When a similar query is raised, the system can quickly retrieve past responses and provide a consistent and accurate answer.

Example Implementation: Consider a food delivery platform using a domain-specific model trained on historical customer interactions. When a customer asks, “What is the minimum order value for delivery in my area?” the model can retrieve and respond with precise information based on the customer’s location and historical data.
