500 portadas distintas de un solo modelo de $0.04: arte de portada con IA, consistente con la marca, en un generador económico
The article describes a low‑cost system for generating hundreds of distinct cover images using a generic AI diffusion model via AWS Bedrock. It relies on prompt engineering, negative prompts, and post‑processing to enforce brand consistency and avoid unwanted text, overlaying the logo with Pillow after image generation. This architecture avoids fine‑tuned models, GPU instances, and auto‑scaling groups, keeping marginal costs at a few cents per cover.
- ▪A FastAPI endpoint constructs prompts, calls the Bedrock text‑to‑image model, and then processes the PNG output with Pillow to resize, convert to WebP, and add a brand logo.
- ▪Brand consistency is achieved by wrapping prompts with a fixed style description and a negative prompt that suppresses text and other unwanted elements.
- ▪Because the model often renders pseudo‑text, the workflow disables text generation in the prompt and adds the official logo in a separate overlay step.
- ▪The design eliminates the need for fine‑tuned models, LoRA adapters, or GPU‑based auto‑scaling, resulting in operational costs near zero and marginal costs of only a few cents per image.
