GPT-4o

GPT-4o is OpenAI's flagship model in the GPT family, designed as a multimodal system that processes both text and images. As OpenAI's primary offering, it represents the company's current generation of large language models, though newer iterations like GPT-5.4 have since been released in the family lineup. The model features a 128,000 token context window and supports both text generation and image analysis capabilities. GPT-4o includes tool calling functionality, enabling it to interact with external APIs and execute functions as part of its responses. It handles chat completion and code generation tasks, with a knowledge cutoff of October 2023. GPT-4o serves organizations requiring multimodal AI capabilities for applications spanning customer service, content creation, and technical documentation. While it remains a capable model within the GPT family, users evaluating OpenAI's offerings should consider how it positions against newer family members for their specific requirements.
