OpenAI: GPT-4.1 Nano

OpenAI's GPT-4.1 Nano is a versatile AI model capable of processing text, images, and files, with an extensive context length of 1,047,576 tokens. It supports tools integration but lacks reasoning capabilities and structured output formats. This model could be suitable for users requiring diverse input modalities and occasional tool use, though its benchmark coverage is limited to five areas, making it less clear how well it performs across different tasks compared to competitors. Given its price of $0.1 per million input tokens and $0.4 per million output tokens, GPT-4.1 Nano might be a cost-effective choice for those focusing on specific use cases with adequate benchmark scores in areas like coding but lower performance in others.
