Book Cover Design
Create genre-appropriate book covers with AI image generation via inference.sh CLI.
Quick Start
curl -fsSL https://cli.inference.sh | sh && infsh login # Generate a thriller cover concept infsh app run falai/flux-dev-lora --input '{ "prompt": "dark moody book cover art, lone figure standing at end of a rain-soaked alley, dramatic chiaroscuro lighting, noir atmosphere, cinematic, high contrast shadows", "width": 832, "height": 1248 }' Install note: The install script only detects your OS/architecture, downloads the matching binary from dist.inference.sh, and verifies its SHA-256 checksum. No elevated permissions or background processes. Manual install & verification available.
Genre Conventions
Readers judge books by covers. Matching genre expectations is critical โ a romance reader will skip a cover that looks like sci-fi, regardless of content.

The Thumbnail Test
Your cover will be seen at 80x120px on Amazon, 60x90px in search results, and ~40x60px on mobile grids. At thumbnail size, readers must be able to identify: The genre (from color and composition) The title (if large enough) The mood (from imagery) Test: shrink your cover to 80px wide. If you can't read the title or identify the genre, redesign.
Thriller
infsh app run falai/flux-dev-lora --input '{ "prompt": "dark cinematic book cover scene, silhouette of a person standing before a foggy bridge at night, single streetlamp casting long shadows, noir atmosphere, high contrast, desaturated blue tint, dramatic tension", "width": 832, "height": 1248 }'
Romance
infsh app run bytedance/seedream-4-5 --input '{ "prompt": "romantic soft-focus scene, couple silhouetted against golden sunset on a beach, warm pink and gold tones, bokeh lights, dreamy atmosphere, soft pastel sky, intimate mood", "size": "2K" }'
Sci-Fi
infsh app run falai/flux-dev-lora --input '{ "prompt": "science fiction book cover art, massive space station orbiting a ringed planet, deep blue and teal color palette, stars and nebula background, hard sci-fi aesthetic, cinematic scale, clean geometric architecture", "width": 832, "height": 1248 }'
Fantasy
infsh app run xai/grok-imagine-image-pro --input '{ "prompt": "epic fantasy book cover illustration, ancient stone castle on a cliff overlooking a misty valley, magical aurora in the sky, rich emerald and gold colors, detailed environment, sense of wonder and adventure", "aspect_ratio": "2:3" }'
Non-Fiction / Business
infsh app run falai/flux-dev-lora --input '{ "prompt": "minimal abstract book cover background, clean gradient from deep navy to white, subtle geometric pattern, professional and modern, negative space, corporate aesthetic", "width": 832, "height": 1248 }'
Typography Rules
AI cannot render text reliably. Generate the cover art/background with AI, then add typography in a design tool.
Title Hierarchy
Title โ largest, most prominent, top 1/3 of cover Subtitle โ smaller, below title or at bottom Author name โ bottom of cover, size depends on author recognition
Font Pairing by Genre
Thriller: bold sans-serif title + condensed sans-serif author Romance: script/cursive title + elegant serif author Sci-Fi: geometric sans-serif for both Fantasy: decorative/medieval serif title + clean serif author Business: heavy bold sans-serif title + light sans-serif subtitle

Checklist
Genre instantly recognizable from colors and composition Title readable at 80px wide (thumbnail test) No AI-generated text on cover Works in both color and greyscale Correct dimensions for target platform Author name visible but not competing with title High resolution (300 DPI for print, 2500px+ for digital) Spine text readable (for print)
