Documented learner outcomes
- Problem Statement – A banking organisation handles large volumes of customer queries related to accounts, transactions, loans, credit cards, banking policies, and services. Traditional support processes can require significant manual effort, while generic AI systems may produce inaccurate or unsupported responses. The challenge is to understand how Large Language Models (LLMs) can be used to build an AI-assisted banking support solution while maintaining accuracy, data privacy, security, and human oversight.
- How We Overcame the Problem – Learners analysed the banking support requirements and designed an LLM-based workflow using appropriate prompts, structured context, controlled inputs, and response validation. They learned how tokens, embeddings, transformer architecture, attention mechanisms, context windows, and model parameters influence LLM behaviour and applied these concepts to create more reliable AI responses.
- Overall Implementation – Learners implemented an LLM-powered banking assistance workflow covering customer query → prompt construction → relevant context → LLM processing → response generation → output validation → final response.
- LLM Fundamentals Implementation – Learners explored how transformer-based LLMs process text, predict tokens, understand contextual relationships, and generate natural-language responses.
- Tokenization and Context Management – Learners examined how banking queries are converted into tokens and how context length affects the information available to the model during response generation.
- Prompt Design – Learners created structured prompts for banking scenarios, including role instructions, customer context, response requirements, constraints, and expected output formats.
- Customer Query Classification – Learners designed workflows for categorising common banking queries such as account information, loan enquiries, card services, transaction questions, and general banking support.
- Knowledge-Based Response Generation – Learners used controlled banking information and contextual instructions to generate relevant responses while reducing unsupported or misleading information.
- Response Validation – Learners evaluated generated responses for accuracy, relevance, completeness, consistency, and compliance with predefined banking response guidelines.
- Model Parameter Exploration – Learners examined concepts such as temperature, token limits, context windows, and other model parameters to understand their impact on response quality and consistency.
- Responsible AI and Security – Learners considered banking-specific requirements including protection of sensitive information, privacy, access control, hallucination management, responsible AI usage, and human escalation for sensitive or high-risk requests.
- Evidence of Learning – Learners produced LLM concept exercises, prompt templates, banking query examples, generated responses, parameter experiments, validation checklists, workflow designs, and implementation documentation demonstrating their understanding of LLM fundamentals.
- Overall Learner Outcome – By completing the implementation, learners demonstrated practical understanding of LLM architecture, transformers, tokens, attention, embeddings, context windows, prompting, model parameters, response generation, evaluation, and responsible AI, and applied these concepts to a realistic banking AI-assistance scenario.
