Canvas: 2:1 aspect ratio landscape banner, approximately 1000 x 500 pixels. Compact composition and rich colors, no white space, visually optimized for SNS post thumbnails. Main Text: A large, bold Japanese title at the top, using bold white font with a black shadow and slight 3D depth effect.{argument name="headline text" default="ChatGPT Image Generation: Major Update!"} Add a smaller, bold white subheading with a black outline, centered directly below the main heading:{argument name="subtitle text" default="GPT-Image-2 is now free to use."} The text should occupy the top third of the area and maintain high readability. Scene: A dazzling anime concert stage with gold glitter, star-shaped decorations, lens flares, neon lines, confetti, glowing particles, and dramatic stage lighting. At the center of the background, a large, glowing OpenAI-style knot-shaped logo is displayed, placed within a warm gold circular halo, partially behind the performers. Futuristic UI monitoring panels are added to the far left and right edges, showcasing colorful sci-fi dashboards, circular interface graphics, music visualizations, and digital control interfaces. Characters: The lower half displays five anime band members, arranged from left to right: 1. The leftmost blue-haired keyboardist, with long blue hair and a white shirt, sits or stands behind the keyboard/synthesizer, presenting a cool idol style. 2. The center leftmost pink-haired lead vocalist, with twin tails adorned with flowers, wears a ruffled pink idol dress, holds a black microphone, and sings with a bright expression. 3. The drummer/core idol with yellow-orange hair in the foreground (center right) has an energetic smile, a star hair clip, and wears a white outfit with a short yellow jacket, waving drumsticks at the audience; a drum set is visible behind him. 4. The bassist or guitarist with green/dark hair in the center right position wears black and green streetwear and holds a dark electric bass/guitar, positioned slightly behind the main character. 5. The guitarist with black hair on the far right wears gothic-style black clothing with straps and accessories and holds a purple electric guitar. Visual Style: Highly detailed Japanese anime-style main visual, idol band aesthetics, glossy digital painting, saturated colors, dynamic lighting, crisp line art, dramatic depth of field, warm gold and magenta highlights, and a celebratory atmosphere reminiscent of tech news. Utilizes cinematic contrast and vibrant composition. Constraints: Maintain 5 performers and 2 visible text blocks. Ensure text is clear and centered.
