Japanese GPT-Image-2 Anime Concert Banner

Objective: Create a vibrant Japanese-style promotional banner announcing an image generation update for ChatGPT/GPT-Image-2, with a style reminiscent of an anime idol rock concert ad. Canvas: A wide, horizontal social media banner, approximately 2:1 in aspect ratio, with a cinematic 1024×512 resolution. The image should fill the entire frame with no white space. Layout: Place a large, bold Japanese title in the top two-thirds, centered and slightly curved, with a heavy black shadow and white fill. Place a smaller, centered subtitle below. The lower half features an anime band performance scene, including five visible characters and a drum kit, surrounded by glowing UI panels, stars, flashing lights, and neon concert lighting. Text Content: Japanese Main Title:{argument name="headline text" default="Image generation using ChatGPT has been significantly updated!"} Japanese subtitle:{argument name="subtitle text" default="GPT-Image-2 is available for free."} The text uses a bold, rounded sans-serif font in bright white with black outlines/shadows to ensure optimal readability against complex backgrounds. Main details: The lower half features five anime band members: 1) Far left, a blue-haired keyboardist in light blue and white clothing, positioned behind the keyboard; 2) Center left, a pink twin-tailed idol singer holding a microphone, wearing a pink stage dress with ruffles and floral hair accessories; 3) Center right foreground, a vibrant, golden/yellow-haired idol drummer/main performer with a smile, holding drumsticks, wearing a cropped yellow jacket, a white top with star patterns and hair clips; 4) Center right, a black-haired guitarist/bassist with green accents, dressed in black streetwear; 5) Far right, a black-haired female guitarist in a black off-the-shoulder rock outfit, holding a purple electric guitar. A gold drum kit is placed behind the two central characters. The central performers should be the most prominent and brightly lit. Background and effects: Behind the band, a glowing, circular, gold OpenAI-style knot-shaped logo is displayed as a stage backdrop. Add futuristic interface screens to the left and right edges, including colorful dashboards, rings, waveforms, and thumbnail panels. Use a deep black and purple concert background, complemented by neon beams of orange, pink, gold, and blue. Scatter numerous glowing pentagrams, musical notes, lens flares, confetti, and rays of light throughout the image. Visual style: Refined modern anime illustrations, idol concert posters, saturated colors, glossy highlights, dramatic rim lighting, high detail, dynamic composition, celebratory atmosphere, clear typography, and strong contrast. Make it look like a thumbnail of a viral Japanese tech news article about AI-generated images. Constraints: Keep the text clear and dominant; do not add extra heading lines except for the designated two lines; keep exactly five band characters; avoid photorealistic style; avoid watermarks; and avoid using illegible tiny text except for decorative UI elements.
