OpenAI: GPT-4o

GPT-4o, developed by OpenAI, boasts an expansive context length of 128,000 tokens and supports text, image, and file inputs, making it versatile for multimedia tasks. It also integrates tools for practical applications but lacks native reasoning capabilities or structured output formats. With a benchmark blended score of 35.0 across two independent evaluations, GPT-4o is suitable for users needing robust handling of diverse input modalities and access to external tools at a cost of $2.5 per million input tokens and $10.0 per million output tokens. This pricing structure might be prohibitive for casual or low-volume users but is viable for those prioritizing extensive context processing and tool integration.
