OpenAI: GPT-4o

GPT-4o from OpenAI is designed for extensive text, image, and file handling with a context length of 128,000 tokens. It supports various input modalities and integrates tools, though it does not perform reasoning tasks or generate structured outputs. While GPT-4o offers robust capabilities, its blended benchmark score of 35.1 across two independent benchmarks may leave room for improvement. Given its price at $2.5 per million input tokens and $10 per million output tokens, this model might be more suitable for users requiring extensive text processing alongside image and file handling who are willing to pay for the additional context length and tool support.
