nano-banana2-gemini31flash-lite/image-to-image-channel-low-price

It delivers ultra-low-latency and cost-effective image generation & editing capabilities. Optimized to achieve latency under 2 seconds and drastically cut TPU computing costs, this model supports high-volume interactive developer workflows and real-time consumer applications, enabling ultra-fast style transfer, inpainting and background replacement. This is a low-cost channel variant, priced far below the official stable version, yet with unstable performance.

Preserve the person’s real identity, facial features, facial proportions, face shape, hairstyle outline, and overall temperament. Do not change the person’s identity. Transform the image into a cinematic rainy-night urban street style: the subject wears a black long trench coat and a white shirt, standing in the middle of a rain-soaked Tokyo street. The wet pavement reflects neon lights, with blurred cars and pedestrians passing in the distance. Keep the face clear, natural, and realistic, with authentic skin texture. The expression should be calm and slightly narrative, with the subject looking into the distance. Use a shallow depth of field to softly blur the background and enhance spatial depth. The overall color palette should include cool blue, purple, and neon tones, with soft lighting and cinematic contrast. The image should feel like realistic photography, shot on a 35mm lens, ultra-detailed 4K quality, refined cinematic color grading, rich details, quiet and restrained atmosphere, strong urban mood. Do not make it look anime. Do not over-beautify the face. Do not change the facial structure. Do not generate extra people. Do not distort the hands or facial features.",
