Context Window
Maximum text an AI can process at once
What is Context Window?
The maximum amount of text an AI model can process and remember in a single conversation turn, measured in tokens. GPT-4 supports 128K tokens (~96K words), while newer models reach 1M+. A larger context window means more documents, code files, or conversation history can be included at once. For bilingual creators, bigger windows allow processing full articles in both languages simultaneously for translation and adaptation.
How it works
Key takeaways
-
Maximum text the model can process at once
-
Longer windows = more context but higher cost
-
Attention dilutes across very long contexts
Real-world example
GPT-4 has a 128K token context window. That's roughly a 300-page book. Feed it more than that and earlier content gets truncated. Choosing what goes in the window is a core skill for effective AI use.
