A photorealistic, slightly angled snapshot of a green classroom chalkboard. On the left side of the board is a large, meticulously drawn chalk illustration of the [OpenAI] logo, rendered in blended pastel colors like green, blue, and purple, with the word "[OpenAI]" written in neat white chalk beneath it. The right side of the board features handwritten chalk text organized into exactly three numbered sections: Section 1 is titled "[1. OpenAI란?]" followed by a brief explanatory paragraph; Section 2 is titled "[2. 주요 제품]" followed by three bullet points listing ChatGPT, DALL-E, and Codex; Section 3 is titled "[3. 특징]" followed by three bullet points describing key features. The chalkboard has an aluminum silver frame and a lower chalk ledge holding two rectangular erasers and scattered chalk pieces. Below the board is an off-white wall with a double electrical outlet. In the bottom-left foreground, the top edge of a dark laptop screen is partially visible, and above the board, the bottom edge of a framed classroom sign is slightly cropped.
