GPT-5.6 Context Window: How to Work With Long Inputs

Use long context intentionally: select relevant material, structure it well, and verify the output on critical tasks.

A large context window can make long-document work easier, but it does not remove the need for good context selection. Give the model well-organised, relevant input and ask it to identify assumptions, missing data, and citations in its output.

Key takeaways

Provide only relevant material instead of every available file.
Use headings, labels, and clear instructions for each source.
Ask for a summary or extraction pass before a high-stakes final answer.
Validate important output against the original source.
