  "account": "When selecting an image generation model for a web app, prioritize the smallest model that meets the visual standards for the marketplace workflow. Focus on measuring the time to a usable result rather than chasing leaderboard rankings. A hosted model with consistent latency is generally the simplest starting point. Self-hosted models become more relevant when control, repeatability, or deployment constraints are more important than operational simplicity.\n\nTo make an informed decision, create a small evaluation set with 30-50 prompts covering various asset classes. Repeat requests where possible, and have at least two reviewers blind-score the outputs based on prompt fidelity, text rendering, composition, and policy failures. Include inconclusive cases like long product names, ambiguous colors, sensitive imagery, and refusals.\n\nRecord two key timestamps: request acceptance and asset usability. The latter is what users perceive. Even a technically valid image generated quickly can be slower if it requires repeated retries for prompt fidelity. Conversely, a slower model with a higher first-pass acceptance rate may perform better for thumbnails or internal drafts.\n\nConsider the service boundary, deployment control, consistency, image quality for the prompt set, and observed latency in the web app's region. Model names alone do not determine these measurements. Conduct thorough testing before committing to an implementation.\n\nWhen building the evaluation set, keep it concise: 10 prompts are enough to reveal a broken setup, while 30-50 prompts provide a more robust assessment. Use idempotency keys to prevent duplicate assets and charges. Implement a clear runtime shape with distinct pending, completed, rejected, timed out, and retryable states. Expose the image generation model API indirectly, separate it from the browser, and use bounded exponential backoff for HTTP 429 responses. Account for all costs, including storage, delivery, retries, moderation, infrastructure, and engineering time. Implement a retention policy tailored to the workflow's risk and value.",
  "summary": "TL;DR: choose the smallest image-generation system that meets the visual bar for the marketplace workflow, then measure time to a usable result instead of chasing a model leaderboard. A hosted model with predictable latency is usually the simplest starting point for text-to-image previews; a self-hosted model becomes reasonable when control, repeatability, or deployment constraints matter more…",
