Picnow Image Generation

Problem

Long 2K/4K image renders can exceed edge timeouts on synchronous image APIs. Picnow wraps the async GPT-Image-2 flow, so the agent submits a job, polls until completion, and returns the final image URL.

How It Works

• Inputs: prompt is required; optional quality (1k/2k/4k), aspect (square/landscape/portrait), n (1–10), and ref (local reference image path).
• Modes: without ref, it runs text-to-image; with a local path, it runs image-to-image editing.
• Execution: calls api.letmego.top under /v1/async/images/..., submits the job, polls for completion, and emits a single JSON result.
• Output: presents each URL as a clickable link or inline image, labels batches like 1/3 and 2/3, and can follow up with download, save, or another variation.

Boundaries

4k supports landscape or portrait only, not 4k square. 1k is best for previews and social media, 2k for e-commerce and print, and 4k for larger deliverables. Errors may involve a missing LETMEGO_API_KEY, invalid token, insufficient balance, upstream 4xx responses, or network issues; handle them by refreshing the token, checking balance, inspecting the upstream message, or retrying.
