What Gemini 3 Pro Image Preview delivers
Gemini 3 Pro image sits at the quality end of the image tiers: detailed scenes, controlled composition and better handling of subtle instructions such as camera angle, palette or mood. It is also comfortable in mixed tasks, where an image and text are processed together — describe a chart, refine a layout, or iterate on a design with follow-up prompts.
That combination suits workflows that are not purely generative: reviewing a mock-up, editing a screenshot, or producing a visual that must match a written brief. Each call is metered per request on OpenLux, so the cost of an iteration loop is visible rather than bundled into a plan.
At $0.0243 per request it is priced above the flash image tier ($0.0122) and gpt-image-2-c ($0.00882), and just above FLUX 2 Pro ($0.021) — worth it when the asset is customer-facing and quality is the constraint.
