OpenAI: GPT-5.4

This AI model from OpenAI is designed for handling large context lengths of up to 1.05 million tokens and supports input modalities including text, image, and file formats. It can also engage in reasoning and uses tools to aid its processing. Additionally, it has the capability to handle multiple types of input simultaneously. Considering the pricing structure, with $2.5 per million input tokens and $15.0 per million output tokens, this model may be a suitable choice for those who require advanced processing capabilities and can afford the associated costs. The benchmark scores indicate a blended score of 83.9 across two independent evaluations, suggesting it is competitive in its performance; however, further analysis would be necessary to determine its full range of abilities.
