It improves visual quality, text rendering, infographic layout accuracy, and multi-turn character consistency across 1K, 2K, and 4K output, fixes tiling artifacts on wide and panoramic aspect ratios, supports up to 14 reference images (up to 4 characters and 10 objects), grounding with Google Web and Image Search, and configurable thinking levels (minimal, medium, high). All outputs carry a SynthID watermark.
