Context Window
A context window is the amount of information an AI model can consider within a single interaction or processing session, typically measured in tokens.
Definition
A context window is the amount of information an AI model can consider within a single interaction or processing session, typically measured in tokens.
A context window is the amount of information an AI model can consider within a single interaction or processing session, typically measured in tokens. The concept is commonly encountered when learning about or working with modern artificial intelligence. Its exact implementation and behavior can vary between models, platforms, and use cases, so it should be understood in the context of the system in which it is being used.
Why It Matters
Context window size determines how much conversation history, documentation, instructions, and other information a model can work with at once.
Real-world Example
A researcher may place several documents into a model's context so the AI can compare information across those sources.

Common Mistakes
- Treating Context Window as interchangeable with every related AI concept
- Ignoring the limitations and context in which Context Window is used
- Relying on AI-generated explanations without verifying important technical or factual claims
