OpenAI: GPT-4o
The OpenAI GPT-4o model is designed for diverse input modalities, including text, images, and files, with a maximum context length of 128,000 tokens. It can leverage tools, but its reasoning capabilities are limited. Considering the pricing structure, which charges $2.5 per million input tokens and $10.0 per million output tokens, this model may be suitable for projects that require high-context understanding or image processing. However, its blended benchmark score of 31.6 across two benchmarks indicates a relatively average performance in comparison to other models.
