OpenAI: o4 Mini (batch)
The OpenAI o4 Mini (batch) is an advanced AI model capable of processing images, text, and files; it supports both reasoning tasks and integration with external tools. With a context length of 200,000 tokens, the model can handle extensive inputs effectively. While it offers robust functionality in terms of modalities and supporting reasoning, structured output capabilities are not explicitly stated. This model should be considered for projects requiring versatile input handling and tool integration, though its high pricing-$0.55 per million input tokens and $2.2 per million output tokens-might limit its use to more critical applications where the blend score of 64.6 across three benchmarks justifies the cost.
