A clean, minimalist promotional poster on an off-white background in a modern tech-brand editorial style. At the top left, a bold sans-serif headline in deep cobalt blue reads "[Thinking Mode Searches]" split across two lines. Beneath it, a smaller gray explanatory sentence explains that with thinking mode, the model can automatically browse the internet and find relevant contents for reference. At the top right, a small blue OpenAI knot logo. Below the intro text, a thin horizontal blue divider line ending with a tiny sparkle icon on the right. Directly underneath, a small prompt line reading: "Prompt: [Make a poster about OpenAI merch available on the official website right now.]". The main section features an 8-item catalog grid displayed inside rounded pale cards with subtle soft shadows. Top row shows 3 larger apparel pieces: 1) a white long-sleeve striped rugby jersey with black collar, cuffs, and blue chest text "Research & Deployment Co.", labeled "10 Year Jersey"; 2) a dark brown pullover hoodie with front pocket and sleeve graphic, labeled "Diagram Hoodie"; 3) a black T-shirt back view showing a metallic knot graphic and pink text "Research & Deployment Co.", labeled "Chrome Blossom Tee". Bottom row shows 5 smaller accessories: 4) a blue folding chair keychain labeled "Blue Chair Keychain"; 5) a black baseball cap with white flames and "GPT-5" labeled "GPT-5 Flame Cap"; 6) a white notebook with a bold blue lower band labeled "OpenAI Notebook"; 7) a glossy black mug with white logo labeled "OpenAI Office Mug"; 8) a dark green cap with "Thinking deeply" text labeled "Thinking Deeply Cap". Product labels are centered beneath each item in small blue sans-serif type.
