GPT Image 1.5 - Oxen.ai

Try GPT Image 1.5 in the Workbench

Run this model interactively, tune parameters, and compare outputs.

Model ID: gpt-image-1-5 GPT Image 1.5 is an image generation model that excels in generating high-fidelity images with strong prompt adherence, while preserving composition, lighting, and fine-grained detail from input images. Some other noteworthy features of GPT Image 1.5 include image-to-image editing, support for resolutions like 1024x1024, 1536x1024, and 1024x1536, and options for adjustable quality, input fidelity, and background (auto, transparent, opaque).
