GPT-4o

GPT-4o is OpenAI's multimodal flagship model released in May 2024, designed to handle text, image, and audio inputs natively. The "o" stands for "omni," reflecting its ability to process multiple modalities seamlessly. With a 128K token context window, GPT-4o provides a substantial improvement in both speed and cost-efficiency compared to earlier GPT-4 variants.

The model achieves strong performance across benchmarks, scoring approximately 88.7% on MMLU (Massive Multitask Language Understanding), with particular strengths in coding and reasoning tasks. Its multimodal capabilities enable it to analyze images, process audio, and generate coherent responses that integrate information across different input types.

GPT-4o is priced at approximately $2.50 per million input tokens and $10 per million output tokens, making it significantly more accessible than previous GPT-4 iterations while maintaining high-quality outputs. It has become a popular choice for production applications requiring fast, reliable, and cost-effective language model capabilities across diverse use cases.
