GPT-5.2

GPT-5.2 is OpenAI's flagship large language model within the GPT family, positioned as their most capable offering for complex reasoning and problem-solving tasks. As a proprietary model, it represents OpenAI's latest advancement in their GPT series, though newer models like GPT-5.4 have since been released within the same family line. The model supports both text and image inputs with a substantial 400,000 token context window, enabling it to process lengthy documents, codebases, and multi-turn conversations. GPT-5.2 includes structured tool calling capabilities and demonstrates strong performance across code generation and chat completion tasks. Its knowledge cutoff of June 2025 provides relatively current information compared to many competing models. GPT-5.2 is commonly deployed for sophisticated applications requiring deep reasoning, complex coding projects, document analysis, and multimodal understanding. While it remains a capable model within OpenAI's lineup, organizations should consider whether the newer GPT-5.4 better meets their requirements for the most demanding use cases.
