Anime GPT-Image-2 Update Banner

Objective: Create a vibrant Japanese social media banner for a major update to ChatGPT's image generation feature, featuring a glossy anime idol band concert poster style. Canvas: 2:1 wide landscape banner, approximately 1000 x 500 pixels, filled with dramatic lights, glitter, star patterns, neon effects, and a celebratory stage atmosphere. Main Heading: A striking, bold white Japanese headline at the top, with a thick black shadow and slightly rounded sans-serif font:{argument name="headline text" default="Image generation using ChatGPT has been significantly updated!"} Below, centered, is a smaller white subtitle with a black outline:{argument name="subheadline text" default="GPT-Image-2 is available for free."} Layout: Five anime band members stand in the lower half, with a glowing gold OpenAI-style badge in the center of the background. There must be five visible characters in the image: a blue-haired keyboardist on the far left, a pink-haired twin-tailed vocalist holding a microphone in the center left center, a cheerful blonde drummer/idol in the center foreground holding drumsticks, a dark green-haired bassist/guitarist in the center right, and a black/purple-haired electric guitarist on the far right. Add rectangular blur masks to the faces of the leftmost, right-middle, and rightmost characters; keep the pink vocalist and the central blonde character fully visible. Character details: The central character is the focus: a vibrant anime girl with {argument name="center character hair color" default="Golden yellow"} A character with twin ponytails, amber eyes, star-shaped hair accessories, a yellow cropped jacket, and a white top, wearing a happy smile, holds drumsticks slightly outstretched towards the audience. A pink-haired lead singer with long, curly twin ponytails wears a pink ruffled idol outfit, adorned with flower accessories, and holds a black microphone. A blue-haired keyboardist in a white shirt plays the keyboard in the lower left corner. Two musicians on the right wear dark rock-style clothing; the guitarist on the far right holds a purple electric guitar. Background and props: A concert stage scene is used, showing four main instrument groups: the keyboard in the lower left corner, the drum set behind the central character, the bass/guitar of the musician on the right, and the purple electric guitar on the far right. Two tilted futuristic displays are added to the background: a large neon interface screen with circular UI graphics on the left, and a screen displaying a colorful landscape/image generation interface on the right. The scene is filled with numerous Venus stars, lens flares, beams of light, musical note icons, and confetti-like glitter. Visual Style: Bright and refined anime illustrations, promotional thumbnail style, using saturated pink/yellow/purple tones, cinematic lighting effects, sharp outlines, bright highlights, compact composition, dynamic perspective, combining a festive atmosphere with a futuristic feel. Maintain eye-catching and legible typography, with the title occupying the top third of the image. Constraints: Strictly retain the specified Japanese text, do not use any English titles, do not add watermarks, do not add any additional logos besides the abstract, glowing OpenAI-style badge, and ensure all five characters are clearly visible in the lower half.
