Ultra-photorealistic lifestyle photo of a young woman working late in a modern Shanghai apartment at night. A sleek silver laptop is open on a wooden desk, next to a minimalist white ceramic mug with faint steam rising. Warm orange indoor light mixes with cool blue city lights from a large window behind her, showing a soft-focus skyline and neon signs. Natural skin texture, detailed hair strands, realistic reflections in the laptop screen and on the table, accurate soft shadows, global illumination, shallow depth of field.

Minimal vertical poster with a clean dark background. Big bold Chinese title at the top: “PiAPI 2025 生成式未来高峰论坛”. Small English subtitle below: “GENERATIVE FUTURE SUMMIT 2025”. A single glowing abstract sphere in the center made of blue and purple light trails.

Top-right panel: “SUMMER / 夏天”, bright sun, lush green trees, the couple sharing ice cream, vivid colors.
