OpenAI: o4 Mini High
The OpenAI o4 Mini High can handle image, text, and file inputs with a context length of 200,000 tokens, supporting tools and reasoning but lacking structured output capabilities. It shines in versatile input modalities and robust tool support. For those needing a model that can process various data types without the complexity of structured outputs, this could be a strong contender; its price of $1.1 per million input tokens and $4.4 per million output tokens makes it cost-effective for tasks requiring image or text handling. With a blended benchmark score of 81 across one independent evaluation, it offers reliable performance, especially in the aider_polyglot task as of August 2026.
