OpenAI: o3 Mini High
The OpenAI o3 Mini High is a language model that supports text and file inputs, allowing it to process long contexts up to 200,000 tokens. It can also support tools and reasoning tasks, but does not provide structured output. This model may be worth considering for users who need to handle large input texts or files, particularly those who require tool integration and reasoning capabilities. Its pricing of $1.1 per million input tokens and $4.4 per million output tokens is a factor to consider, as are its benchmark scores across four independent tests, which average 31.5 points in the blended score.
