Iteration
Repeating a process to improve results, like refining a chat response or updating a spreadsheet.
Iteration means making changes and improvements step by step. Think about editing a document. You might write a first draft, then revise it, then edit it again to make it better. Each pass is an iteration.
In AI, iteration is how models and tools get better. For example, when you chat with an AI assistant, it might go through several internal iterations to understand your request and give you the best answer. If the AI can edit a spreadsheet, it might iterate on the changes it makes to ensure they are correct.
Iteration refers to the process of repeating a procedure or algorithm, often with the goal of refining output or approaching a target state. In machine learning, this is fundamental to training, where models are updated over many passes through data. In interactive AI systems, iteration can describe the back-and-forth between a user and the model, or the internal steps the model takes to generate a response or execute a task, such as modifying a document or code.
Recent advancements allow AI tools like Microsoft Copilot to directly modify user files, showcasing iterative refinement of tasks. This moves beyond simple generation to active, step-by-step task completion and correction.

The term 'iteration' originates from mathematics and computer science, referring to the repetition of a process. Its application in AI is a direct extension of these foundational concepts.
Ask an AI chatbot to write a short poem. Then, ask it to make the poem funnier or change the subject. Notice how the AI revises its previous output based on your new instructions, showing an iterative improvement process.

Questions people ask
- What's the difference between iteration and a single attempt?
- An iteration is a specific step in a process aimed at improvement. A single attempt might just be a first try without a clear plan for refinement.
- How do AI models use iteration?
- AI models use iteration extensively during training to learn from data and also in generating responses, where they might refine their output multiple times.
