Confirmed
- LMArena officially announced that Sunburst and Flare rank first and second respectively across the text-to-image, single-image editing, and multi-image editing arenas, both significantly surpassing GPT-Image-2 (medium), and also sweeping the top two in all subcategories such as 3D modeling and art
- A repost noted Sunburst's multi-image editing score surged by 81 points
