On 4 November 2026 OpenAI added SVG output in the Image API with GPT Image 2.6 Sunburst and Flare. Before using an exported icon, inspect its edges at the size and in the application where it will appear. A file that opens successfully can still lose part of its outline.
Compare geometry with the bounds
The viewBox defines a rectangle in drawing coordinates. For a circle centered at (50, 50) with radius 50 and a centered stroke 8 units wide, the painted bounds are −4 to 104 on both axes. The rectangle described by viewBox='0 0 100 100' stops at the centerline of the stroke at each extreme. As a starting point, try viewBox='-5 -5 110 110'. That leaves one drawing unit beyond the stroke on each side. The outer viewport and clipping settings still affect what you see.
Ask the assistant to explain the intended bounds and preserve the design while adding appropriate space or adjusting geometry. Do not stretch the icon just to hide a cut edge.
Check the real destination
Open the SVG at small and large sizes, then test it in the actual slide, page or image export. Inspect every edge and any shadow, whose bounds may differ from the shape. Keep the original file and compare the revised silhouette. Correct XML syntax does not guarantee correct framing, and a successful preview in one application does not prove identical rendering everywhere.
OpenAI says API organization verification may be required for GPT Image models. Check access and pricing for your API organization before generating anything. The circle above is a drawing example.
