OpenAI's latest GPT model is a versatile, general-purpose AI that handles text, code, images, and audio with a focus on accuracy and practical utility. It is well suited for building chat assistants, coding copilots, content and report generation, data analysis, and multimodal understanding, from reading images to working with speech. Standout features include native function calling and structured outputs for reliable tool use and integration, plus smooth support for agents and realtime interactions like voice experiences. The model can connect to web search, code execution, and retrieval to ground answers, and it works with file inputs for tasks like summarizing PDFs. It also supports safety and moderation tools, as well as optimization and fine-tuning options, making it a strong choice when you want one model to power both simple prompts and complex, tool-augmented workflows.
