OpenAI: GPT-4.1

GPT-4.1 is a paid model from OpenAI that accepts text, images, and files as input, supports tool use, and offers a context window of roughly one million tokens. It does not include a built-in reasoning mode, and structured output support is unconfirmed. The large context window makes it practical for tasks involving long documents or multi-file inputs where fitting everything into a single prompt matters. At $2.00 per million input tokens and $8.00 per million output tokens, it sits in the mid-range of current frontier pricing. Its blended benchmark score of 53.9 covers only three benchmarks, so that figure should be treated as a limited signal rather than a confident ranking. Users who regularly need to process large volumes of text or mixed file inputs, and who require tool integration, have a concrete reason to shortlist it; those prioritizing cost efficiency or verified reasoning capabilities may find stronger alternatives depending on their workload.
