Full Release Notes

- **Artwork that belongs on your page.** Impeccable can now generate illustrations and objects with genuinely transparent backgrounds, ready to sit over your own colors and textures. Photos and full-frame artwork keep their backgrounds.

- **GPT Image 2.5 joins the workflow.** Flare now powers image generation and reference edits when Impeccable uses your OpenAI key. Your agent's native image tool remains the first choice.

- **More iterations, less waiting.** In our 24-image comparison, Flare reduced median generation time from 88 seconds to 18, with approximately 73% lower estimated cost.

- **Cutouts get a closer look.** Asset production checks white details, fine edges, and interior gaps on light and dark backgrounds, then refines visible misses. Fidelity checks account for transparency against the reference background.
