  "account": "When selecting a text-to-image API for marketing posters and social ads, prioritize prompt adherence and style control before considering output resolution. Upscale should be treated as an optional export step. For content with legible copy, consider OpenAI's images endpoint or Imagen on Vertex AI. If you require seeds and swappable checkpoints, opt for Replicate or Amazon Bedrock. For a single marketing app handling both posters and social ads, a multi-vendor gateway may be preferable.\n\nThe three main culprits that destroy ad creatives are prompt adherence, in-image typography, and artifact rate. Prompt adherence ensures the model accurately interprets and executes your instructions. In-image typography refers to the text within the generated image; any errors here are not easily rectified with higher resolution. Artifact rate, often a cost factor, indicates the number of rejected images due to issues like mangled hands or logo edges. A model with slightly poorer aesthetics but a lower reject rate is more cost-effective and efficient.\n\nThe resolution and upscale quality matter less for social ads, but more for print posters. Most social platforms have resolution limits, whereas A3 physical posters require much higher pixel density (300 dpi, roughly 3500x4900 pixels). Upscaling falls into two categories: resampling (clean resizing with no invented content) and generative super-resolution (adding plausible detail that wasn't originally present). Infrai's image upscale endpoint is suitable for clean resampling, while Real-ESRGAN or commercial upscalers can be used for generating detail for billboards. For social ads, resampling is usually sufficient.\n\nA lesson learned: a nightly job generating 200 images for a campaign resulted in an invoice of $317 due to unnecessary fan-out and lack of separate cost tracking. To avoid this, limit fan-out to three, generate ratios for actual placements, and tag each request for cost allocation. Most people experience surprise billing due to excessive fan-out, not the unit price. The recommended shortlist includes OpenAI Images REST or SDK, Imagen on Vertex AI, Amazon Bedrock, Replicate, and Infrai. Each service offers varying degrees of style control and upscaling options, suitable for different types of brands and projects.",
  "summary": "Bottom line: rank a text-to-image API by prompt adherence and style control first, output resolution second, and treat upscale as an optional export step — OpenAI's images endpoint or Imagen on Vertex AI when the creative carries a lot of legible copy, Replicate or Amazon Bedrock when you want seeds and swappable checkpoints, and a multi-vendor gateway when you'd rather hold one account than four…",
