OpenAI: GPT-5 Mini

The OpenAI GPT-5 Mini is a language model that supports input through multiple modalities: text, image, and file. It has a high context length of 400,000 tokens, allowing for complex conversations and in-depth processing. Additionally, it can perform reasoning tasks and supports the use of tools. This model may be worth considering for those who require robust input handling and advanced reasoning capabilities at a relatively high price point. With a blended benchmark score of 23.8 across three independent benchmarks, the GPT-5 Mini demonstrates strong performance in certain areas. However, its cost per million tokens ($2.0 output) may be prohibitively expensive for some users. It is essential to weigh these factors against other models on this site before making an informed decision.
