OpenAI: o3 Mini
The OpenAI o3 Mini model is designed for handling text and file input modalities up to 200,000 context length. It supports tools and reasoning capabilities, but does not produce structured output. Considering its price point of $1.1/M input tokens and $4.4/M output tokens, the o3 Mini may be worth shortlisting for users seeking a balance between cost and performance. Its blended benchmark score of 40.9 across two benchmarks suggests it can deliver reasonable results in certain tasks; however, its coverage is limited to only two benchmarks.
