GPT-IMAGE-2 drops transparent image support

A Reddit user flagged that GPT-IMAGE-2 no longer produces transparent-background PNGs the way GPT Image 1.5 could. OpenAI's current image-generation docs confirm the limitation: gpt-image-2 does not currently support background: "transparent".

// ANALYSIS

This is a meaningful regression for asset-generation workflows, even if GPT-IMAGE-2 improves resolution, fidelity, and editing elsewhere.

–Developers building sticker, icon, game-asset, ecommerce, and design-tool pipelines now need post-processing or an older GPT Image model for alpha-channel output
–The confusing part is UX mismatch: users can ask for transparency, but the new model's supported output controls explicitly exclude it
–GPT-IMAGE-2 still accepts alpha-channel masks for edits, so OpenAI supports transparency as input guidance while dropping transparent final outputs
–For API users, this is the kind of model migration detail that should be feature-gated, not discovered through failed generations
