What is a Context Window?

The context window is the maximum number of tokens an AI model can process in a single interaction — including both input (your prompt) and output (the model's response). Larger context windows allow for longer documents, more conversation history, and more complex tasks.

Important Notes

  • Context window and pricing data last updated February 2026.
