Context Window

Maximum text an AI can process at once

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.
