GPT-4.1 Mini or GPT-5 Image Mini: which to pick
Neither model has a coding score yet, so the two cannot be ranked on coding.
Pick GPT-4.1 Mini for output tokens 1.3x cheaper ($1.60 vs $2.00 per million) and a larger context window (1.05M against 400K tokens).
No benchmark has tested both yet. GPT-4.1 Mini has results on Aider polyglot, SWE-bench Verified and AA Coding Index; GPT-5 Image Mini on Design Arena: images, Design Arena: graphic design and Design Arena: logos. Compare them on price and context instead.
