OpenAI: o3 Mini High
The OpenAI o3 Mini High is capable of handling both text and file inputs within an extensive context length of 200,000 tokens, making it suitable for complex tasks that require understanding of large documents or datasets. It supports reasoning and tools integration but does not offer structured output directly. With a blended benchmark score of 34.2 across four independent benchmarks, the model demonstrates strong performance in certain areas like polyglot tasks but lower scores in others such as coding and agentic abilities. Given its pricing at $1.1 per million input tokens and $4.4 per million output tokens, this model is more suited for users prioritizing specific applications with a need for extensive context understanding, even though its overall benchmark coverage remains somewhat limited.
