📌 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.

Transformation Scorecards
Transformation scorecards are tools used to track progress and measure success during significant changes within an organisation, such as digital upgrades or process improvements. They present key goals, metrics, and milestones in a clear format so that teams can see how well they are moving towards their targets. By using transformation scorecards, organisations can quickly identify areas that need attention and adjust their approach to stay on track.
Decentralised Identity (DID)
Decentralised Identity (DID) is a way for people or organisations to control their digital identity without relying on a central authority like a government or a big company. With DIDs, users create and manage their own identifiers, which are stored on a blockchain or similar distributed network. This approach gives individuals more privacy and control over their personal information, as they can decide what data to share and with whom.
Proof of Burn
Proof of Burn is a method used in some cryptocurrencies to verify transactions and create new coins. It involves sending tokens or coins to a public address where they cannot be accessed or spent, essentially removing them from circulation. This process is used to demonstrate commitment or investment in the network, as participants must sacrifice something of value to take part.
Cognitive Automation Frameworks
Cognitive automation frameworks are structured sets of tools and methods that help computers carry out tasks that usually require human thinking, such as understanding language, recognising patterns, or making decisions. These frameworks combine artificial intelligence techniques like machine learning and natural language processing to automate complex processes. By using these frameworks, organisations can automate not just repetitive tasks but also those that involve judgement or analysis.
Domain Management
Domain management is the process of registering, configuring, and maintaining internet domain names for websites or online services. It involves tasks such as renewing domain registrations, updating contact information, managing DNS settings, and ensuring domains are secure and active. Proper domain management helps ensure that websites remain accessible and protected from unauthorised changes or expiry.
