OpenAI: o3 Pro

The OpenAI o3 Pro model is designed for handling diverse input modalities, including text, files, and images, with a maximum context length of 200,000 tokens. It also supports tools and reasoning capabilities, but does not provide structured output. For users who need to process large amounts of information from various sources, the OpenAI o3 Pro model may be worth considering due to its ability to handle complex input modalities and perform reasoning tasks. However, its price point is relatively high at $20 per million input tokens and $80 per million output tokens. With a blended benchmark score of 77.6 across two independent benchmarks, it holds an average standing among comparable models, making it a viable option for those who can afford the cost.
