OpenAI: o3 Pro
The OpenAI o3 Pro is a versatile AI model capable of processing text, files, and images, with a substantial context length of 200,000 tokens. It supports reasoning and tools integration but does not offer structured output. At $20 per million input tokens and $80 per million output tokens, it's on the higher end of pricing; however, its blended benchmark score of 77.3 across two independent benchmarks positions it as a robust choice for those needing extensive text generation and multimodal support.
