Describe the scene and subject, choose settings, and generate bold tech video thumbnails that communicate the topic at a glance.

An agent AI thumbnail generator creates custom thumbnail images for tech and AI videos from text descriptions. You describe the main subject (robot, dashboard, diagram), the color palette, and the mood, then generate an image. The result should show one clear focal point and work well at small sizes, so viewers understand the topic instantly before clicking.
Input
a friendly robot assistant floating above a laptop, glowing connection nodes around it, clean white background, cool blue accents
Expected output
a clean AI-themed image with a clear robot focal point and space for a title overlay
Input
a chain of glowing gears feeding into a dashboard, warm orange light on a dark background, crisp lines
Expected output
a crisp automation-themed image with a strong visual flow from gears to dashboard
Input
two stylized brain icons facing each other over a split background, one blue side and one green side, minimal design
Expected output
a balanced comparison-style image with two clear focal points and distinct color zones
