OpenAI: GPT-4.1 Nano
The OpenAI GPT-4.1 Nano is designed for handling text, image, and file inputs with a context length of 1,047,576 tokens. It supports integrating tools but lacks native reasoning capabilities or structured output formats. This model's price stands at $0.1 per million input tokens and $0.4 per million output tokens. While its blended benchmark score of 15.4 across five independent tests is solid, it may not outshine competitors in specialized areas like coding or polyglot tasks, which the GPT-4.1 Nano scores lower on. However, for those looking to integrate tools and handle a variety of input modalities at a reasonable cost, it remains a viable choice.
