📌 Prompt Overfitting Summary
Prompt overfitting happens when an AI model is trained or tuned too specifically to certain prompts, causing it to perform well only with those exact instructions but poorly with new or varied ones. This limits the model’s flexibility and reduces its usefulness in real-world situations where prompts can differ. It is similar to a student who memorises answers to specific questions but cannot tackle new or rephrased questions on the same topic.
🙋🏻♂️ Explain Prompt Overfitting Simply
Imagine learning to answer only the questions your teacher gives you for revision, but struggling when the test has different wording. That is what happens when an AI model is overfitted to certain prompts. The model becomes good at those specific cases, but less able to handle anything unexpected or new.
📅 How Can it be used?
Avoiding prompt overfitting ensures that AI chatbots respond well to a wide range of user questions, not just the ones seen during development.
🗺️ Real World Examples
A company develops a customer support chatbot by training it on a fixed set of questions and answers. When customers phrase their queries differently, the chatbot fails to respond accurately because it has become overfitted to the original prompts.
An AI writing assistant is fine-tuned using only a few types of prompts for generating emails. When users try new ways of asking for help, the assistant gives irrelevant or low-quality suggestions, showing its lack of generalisation.
✅ FAQ
What does prompt overfitting mean for how an AI answers questions?
Prompt overfitting means the AI may give great answers only when you use very specific instructions it has seen before. If you phrase your question differently or ask something similar in a new way, the AI might struggle or give less useful answers. This makes it less helpful in everyday situations where people naturally ask things in lots of different ways.
Why is prompt overfitting a problem for using AI in real life?
Prompt overfitting makes an AI less flexible. In real life, people rarely ask questions in exactly the same way every time. If the AI only does well with certain prompts, it cannot adapt to new or unexpected questions. This limits its usefulness outside of controlled settings and makes it harder for people to get the help or information they need.
Can prompt overfitting be prevented when training AI?
Yes, prompt overfitting can be reduced by exposing the AI to a wide variety of questions and instructions during training. By encouraging the model to handle many different ways of asking things, it becomes better at understanding and responding to new prompts, making it more reliable and helpful for everyone.

AI Governance RACI Matrix
An AI Governance RACI Matrix is a tool used to define roles and responsibilities for managing, developing, and overseeing artificial intelligence systems within an organisation. RACI stands for Responsible, Accountable, Consulted, and Informed, which are the four key roles assigned to tasks or decisions. By mapping out who does what in AI governance, organisations can ensure clear communication, reduce confusion, and help meet compliance or ethical standards.
Service Desk Automation
Service desk automation uses technology to handle routine support tasks and requests, reducing the need for manual intervention. It can process common queries, assign tickets, and provide updates automatically, making support faster and more consistent. Automation helps teams focus on more complex issues while improving the speed and reliability of customer service.
AI for Circular Economy
AI for Circular Economy refers to the use of artificial intelligence to help create systems where resources are kept in use for as long as possible, waste is minimised, and products are reused or recycled. AI can analyse data to optimise how materials are collected, sorted, and processed, making recycling more efficient. It also helps businesses design products that can be more easily repaired, reused, or recycled, supporting a sustainable approach to production and consumption.
Decentralised Autonomous Organisation (DAO)
A Decentralised Autonomous Organisation, or DAO, is an organisation managed by rules encoded as computer programs on a blockchain. It operates without a central leader or traditional management, instead relying on its members to make collective decisions. Members usually use digital tokens to vote on proposals, budgets, or changes to the organisation.
Token Usage
Token usage refers to the number of pieces of text, called tokens, that are processed by language models and other AI systems. Tokens can be as short as one character or as long as one word, depending on the language and context. Tracking token usage helps manage costs, performance, and ensures that the input or output does not exceed system limits.
