OpenAI: GPT-4.1

GPT-4.1 is a paid multimodal model from OpenAI that accepts text, images, and files as input. It supports tool use and offers a context window of roughly one million tokens, which is large enough to process book-length documents or long codebases in a single pass. It does not include a built-in reasoning mode, and structured output support is unconfirmed based on available data. At $2.00 per million input tokens and $8.00 per million output tokens, it sits in the mid-range of frontier model pricing. Its blended benchmark score of 53.9 is drawn from only three benchmarks, so treat that figure as a partial signal rather than a definitive ranking. Teams that need broad file and image handling alongside a very long context window will find it worth evaluating, but buyers who prioritize reasoning tasks or want extensive benchmark coverage before committing should compare it against better-documented alternatives first.
