GPT-4 Turbo Preview

About GPT-4 Turbo Preview

GPT-4 Turbo is OpenAI's enhanced version of GPT-4, featuring a massive 128K token context window—equivalent to approximately 300 pages of text. Released in November 2023, it introduced significant improvements including updated knowledge through April 2024, improved instruction following, and native JSON mode for structured outputs. GPT-4 Turbo delivers the same exceptional reasoning capabilities as GPT-4 but at 3x lower cost, making advanced AI more accessible for production applications. The model excels at complex analysis, long-document processing, code generation, and creative tasks requiring extensive context. It supports vision capabilities for image understanding, function calling for tool integration, and reproducible outputs with seed parameters. GPT-4 Turbo is particularly valuable for enterprise applications involving legal document analysis, research synthesis, and codebase understanding where the extended context window provides crucial advantages. While GPT-4o has since become the recommended model for most use cases, GPT-4 Turbo remains an excellent choice for applications specifically requiring its unique characteristics or for users with existing integrations.
