Benchmarks vs Real-World Testing
Despite GPT-Image-1.5's clear benchmark leadership, early community testing reveals a more nuanced picture. Side-by-side comparisons between GPT-Image-1.5 and Google's Nano Banana Pro consistently highlight an aesthetic difference that benchmark scores don't capture: GPT-Image-1.5 outputs tend toward a "commercial photography" look—polished, professionally lit, but visibly artificial—while Nano Banana Pro produces images with a "candid photograph" aesthetic that many users find more authentic.
Important Context: Benchmark rankings measure aggregate preferences across diverse use cases. Your specific requirements—photorealism vs commercial polish, speed vs quality, editing precision vs generation fidelity—may favor different tools. Always test against your actual production needs.
This disconnect raises a valid question: what are benchmarks actually measuring? Arena evaluations compare model outputs in head-to-head preference tests, aggregating thousands of human judgments. These scores reflect overall quality as perceived by diverse evaluators, but they may weight certain characteristics (instruction following, technical accuracy, visual appeal) differently than any specific user's requirements.
GPT-Image-1.5 Strengths
- Benchmark-leading instruction following
- Superior text and typography rendering
